Internet Printing Protocol / 1.1: Model and Semantics, January 2017, Internet "https://tools.ietf.org/html/rfc8011"

The memory capacity of the printer is finite. The present specification provides a technique capable of compressing the data size stored in the memory when the memory of the image processing device should store the setting data related to the image processing.

The image processing apparatus disclosed in the present specification is an image processing execution unit for executing image processing and a memory capable of storing reference data which is a reference of setting data related to the image processing, and is the reference. The data includes the registration of the first setting data from the memory and the terminal device, which includes N values corresponding to N setting items (the N is an integer of 2 or more) for executing the image processing. A difference data generation unit that generates first difference data related to a difference between the reference data and the first setting data when the first registration request to be requested is received. The setting data of 1 includes N values corresponding to the N setting items, and for N1 setting items (the N1 is an integer of 1 or more and less than the N) among the N setting items. Regarding N2 setting items other than the N1 setting item among the N setting items whose values are different between the reference data and the first setting data, the reference data and the first setting item. When the value is the same as that of the setting data of 1, the first difference data includes N1 values corresponding to the N1 setting items in the first setting data, and also includes The difference data generation unit that does not include the N2 values corresponding to the N2 setting items in the first setting data, and the storage control that stores the generated first difference data in the memory. When a data acquisition request is received from the terminal device after the first difference data is stored in the memory, the first difference data is used by using the reference data and the first difference data. The setting data transmission unit that generates the setting data of the above and transmits the first setting data to the terminal device, and the first setting data from the terminal device after the first setting data is transmitted to the terminal device. When the execution request of the image processing including the two or more values indicated by the setting data of is received, the image processing control for causing the image processing execution unit to execute the image processing according to the two or more values. It has a part and.

According to the above configuration, the image processing apparatus realizes registration of the first setting data by storing the first difference data related to the difference between the reference data and the first setting data in the memory. can do. Here, the first difference data includes N1 values having a difference from the reference data, but does not include N2 values having no difference from the reference data. Therefore, the data size stored in the memory can be compressed as compared with the configuration in which the N values themselves corresponding to the N setting items included in the first setting data are stored in the memory.

Further, the image processing apparatus disclosed in the present specification is an image processing execution unit for executing image processing and a memory capable of storing reference data which is a reference of setting data related to the image processing. The reference data includes the memory and the terminal including an identifier that identifies the setting item and an item name corresponding to the setting item for each of one or more setting items for executing the image processing. When the first registration request requesting the registration of the first setting data is received from the apparatus, the reference data is used to generate material data as a material for generating the first setting data. In the material data generation unit, the first setting data includes, for each of one or more setting items of the image processing, an item name indicating the setting item and a value corresponding to the setting item. The material data includes, for each of the one or more setting items, an identifier that identifies the setting item and a value corresponding to the setting item, and the length of the identifier is the length of the item name. A shorter data data generation unit, a storage control unit that stores the generated material data in the memory, and a data acquisition request are received from the terminal device after the material data is stored in the memory. In this case, the setting data transmission unit that generates the first setting data by using the reference data and the material data and transmits the first setting data to the terminal device, and the first setting data. After the setting data is transmitted to the terminal device, when the terminal device receives the execution request of the image processing according to the one or more values indicated by the first setting data, the one or more. An image processing control unit that causes the image processing execution unit to execute the image processing according to the value of.

According to the above configuration, the image processing apparatus can realize the registration of the first setting data by storing the material data as the material for generating the first setting data in the memory. Here, the first setting data includes an item name and a value. Material data, on the other hand, includes identifiers and values. The length of the identifier is shorter than the length of the item name. Therefore, the data size stored in the memory can be compressed as compared with the configuration in which the registration of the first setting data is realized by storing the first setting data itself in the memory.

A control method for realizing the above-mentioned image processing apparatus, a computer program, and a computer-readable recording medium for storing the computer program are also new and useful.

(First Example)
(Configuration of communication system 2; FIG. 1)
As shown in FIG. 1, the communication system 2 includes a printer 10 and a terminal 100. The printer 10 and the terminal 100 belong to the same LAN (abbreviation of Local Area Network) 4, and can communicate with each other via the LAN 4. The LAN 4 may be a wired LAN or a wireless LAN.

(Configuration of printer 10)
The printer 10 is a peripheral device (that is, a peripheral device of the terminal 100) capable of executing printing processing. The printer 10 may be a multifunctional machine capable of performing scan processing, fax processing, and the like in addition to printing processing. The printer 10 includes an operation unit 12, a display unit 14, a print execution unit 16, a LAN interface (hereinafter, the interface is referred to as “I / F”) 20, and a control unit 30.

The operation unit 12 includes a plurality of keys. The user can input various instructions to the printer 10 by operating the operation unit 12. The display unit 14 is a display for displaying various information. The display unit 14 also functions as a so-called touch panel (that is, an operation unit). The print execution unit 16 is a printing mechanism such as an inkjet method or a laser method. The LANI / F20 is connected to the LAN4.

The control unit 30 includes a CPU 32 and a memory 34. The CPU 32 executes various processes according to the program 40 stored in the memory 34. The memory 34 is composed of a volatile memory, a non-volatile memory, and the like. The memory 34 stores the reference data 42 and the preset table 44.

The reference data 42 is data that serves as a reference for preset data according to IPP (abbreviation of Internet Printing Protocol). The preset data includes a plurality of setting values corresponding to a plurality of setting items (for example, the number of copies, the number of colors, the image quality, the size, etc.) for executing the printing process. Then, in the reference data 42, for each of the plurality of setting items, the identification number (that is, No) that identifies the setting item, the item name (that is, Attribute Name) of the setting item, and the setting corresponding to the setting item are set. Includes a value (ie, Attribute Value). The identification number is, for example, a serial number. The reference data 42 is stored in the memory 34 in advance at the shipping stage of the printer 10.

For each of the one or more preset data, the preset table 44 stores one or more preset information which is a material for generating the preset data. The preset information includes a preset name, a user name, and difference data. The preset name is information for identifying the preset data. The user name is information for identifying a user who uses a printer (for example, printer 10). In the modified example, the user name may be information for identifying a user who uses the terminal (for example, the terminal 100). The difference data is data related to the difference between the reference data 42 and the preset data. The difference data includes, for each of the plurality of setting items, an identification number (that is, No) that identifies the setting item, a difference flag, and a setting value (that is, Attribute Value) corresponding to the setting item. The difference flags are "YES" indicating that there is a difference between the set value in the reference data 42 and the set value in the preset data for the same setting item, and "NO" indicating that there is no such difference. And, one of the values is shown.

(Configuration of terminal 100)
The terminal 100 is a stationary terminal device such as a PC. In the modified example, the terminal 100 may be a portable terminal device such as a smartphone, a tablet PC, or a notebook PC. The terminal 100 stores a user name UN for identifying a user who uses the terminal 100.

The terminal 100 includes an IPP program (not shown) installed from a server on the Internet. The IPP program is a program for generating an IPP command according to HTTP (abbreviation of Hyper Text Transfer Protocol) and transmitting the command to the printer 10. In this embodiment, the server is provided by a business operator different from the vendor of the printer 10. However, in the modified example, the above server may be provided by the vendor of the printer 10. The terminal 100 may support IPP in advance without installing the IPP program from the above server.

(Structure of preset data; Fig. 2)
The structure of preset data according to IPP will be described with reference to FIG. The preset data includes a preset name and an object. FIG. 2 describes the structure of the object. The object includes Attribute Syntax, Length of Attribute Name, Attribute Name, Length of Attribute Value, and Attribute Value.

Attribute Syntax indicates the syntax of the corresponding Attribute Value. The Attribute Syntax indicates, for example, one of "integer", "enum", "boolean", "keyword", "text", "name", and "octetString". In IPP, values other than the above values are defined as Attribute Syntax, but the description thereof will be omitted.

"Integer" indicates that the Attribute Value has an integer syntax. Indicates that the "enum" Attribute Value has the syntax of an enumerated identifier. "Boolean" indicates that the Attribute Value has the syntax of a logical value (ie, either "true" or "false"). “Keyword” indicates that the Attribute Value has a character code syntax such as US-ASCII. "Text" indicates that the Attribute Value has a relatively long string syntax. "Name" indicates that the Attribute Value has the syntax used for user-friendly strings such as printer names. Note that "text" and "name" are essentially the same. "OctetString" indicates that the Attribute Value has the syntax of Opaque data.

The maximum length of the Attribute Value of "integer" and "enum" is 4 octets, and the maximum length of the Attribute Value of "boolean" is 1 octet. The maximum length of the Attribute Value of "text" and "octetString" is 1023 octets, and the maximum length of the Attribute Value of "name" is 255 octets. The maximum length of the "keyword" Attribute Value is not specifically defined. That is, the maximum length of an Attribute Value with the syntax "integer", "enum" and "boolean" is greater than the maximum length of the Attribute Value with the syntax "text", "octetString", "name" and "keyword". Is also short.

The Attribute Name is an item name indicating a setting item for executing the printing process. Length of Attribute Name indicates the length of Attribute Name. The item names of the setting items are, for example, the number of copies (copies), the number of colors (print-color-mode), the print surface (sides), the image quality (print-quality), the print medium (media), and the like. In IPP, item names other than the above item names are also defined as Attribute Names, but the description thereof will be omitted.

Attribute Value is a setting value corresponding to a setting item for executing the printing process. Length of Attribute Value indicates the length of Attribute Value. For example, when the setting item is "the number of colors", the setting value is "monochrome" or "color". When the setting item is "print side", the set value is one of "single side", "double-sided long-edge binding", "double-sided short-edge binding", and the like. When the setting item is "printing medium", the setting value is any of the sizes of the printing medium, such as A3, A4, and B5.

As shown in FIG. 2, for example, the Attribute Syntax of the setting item "Number of copies" indicates "integer", the Attribute Syntax of the setting item "Number of colors" indicates "keyword", and the Attribute Syntax of the setting item "Image quality". Indicates "enum".

(Registration of new preset data; Fig. 3)
The process of registering preset data will be described with reference to FIG. Here, "registering preset data" means storing preset information as a material for generating preset data in the preset table 44. In the initial state of FIG. 3, the preset table 44 does not yet store the preset information associated with the user name UN (that is, the preset information including the user name UN). In the following, unless otherwise specified, the processing executed by the CPU 32 of the printer 10 will be described mainly by the printer 10 without describing the CPU 32 as the main body from the viewpoint of easy understanding. Further, in the following, the printer 10 and the terminal 100 communicate with each other via LAN4 and LANI / F20. In the following, unless otherwise specified, the description "via LAN4" and "via LANI / F20" will be omitted.

When the terminal 100 receives an operation for displaying a print setting screen for inputting a print processing setting value in T10, the terminal 100 issues a Get-Printer-Attributes command (hereinafter referred to as "GPA") in T12. It is transmitted to the printer 10. The GPA transmits capability information indicating all the printing conditions that the printer 10 can execute (for example, "monochrome", "color", "single-sided", "double-sided long-edge binding", "double-sided short-edge binding", etc.). Is a command that requests the printer 10. In addition, the GPA includes the user name UN.

When the printer 10 receives the GPA from the terminal 100 at the T12, the printer 10 executes the authentication of the user name UN in the GPA at the T22. In the case of FIG. 3, the authentication of the user indicated by the user name UN is successful. If the GPA does not include the user name, the printer 10 transmits a screen request for displaying the input screen for inputting the user name on the terminal 100 to the terminal 100.

When the user authentication is successful, the printer 10 transmits a capability response, which is a response to the GPA, to the terminal 100 at T26. FIG. 3 describes a situation in which preset information is not yet stored. In this situation, the ability response includes ability information and no preset data. The situation in which one or more preset information is stored will be described with reference to FIG. 7, which will be described later.

Upon receiving the capability response from the printer 10 at T26, the terminal 100 displays a print setting screen (not shown) and a preset screen at T30. The print setting screen includes an input field for inputting a setting value matching the ability information included in the ability response. The preset screen also includes a list of registered preset data and a "New" button for registering new preset data. In the situation of FIG. 3, the list is empty because there is no preset information associated with the username UN.

At T32, the terminal 100 accepts the user to select the "New" button. At T34, the terminal 100 displays a registration screen for registering new preset data. The registration screen includes a preset name input field for inputting a preset name, a plurality of setting input fields for inputting setting values matching the ability information included in the ability response, and an "OK" button. .. For example, a plurality of setting value input fields include a field for inputting the number of colors, a field for inputting the number of copies, a field for inputting image quality, a field for inputting a print surface, and printing. Includes a field for entering the size of the medium. On the registration screen, a value may be input in at least one of a plurality of setting value input fields.

In T35, the terminal 100 accepts the input of the preset name "Preset1", the number of colors "monochrome", and the number of copies "1" on the registration screen. At T36, the terminal 100 accepts the selection of the "OK" button in the registration screen.

In T38, the terminal 100 generates preset data PD1 including the preset name "Preset1" input in T35 and the object indicating the set value (that is, "monochrome", the number of copies "1") input in T35. ..

At T40, the terminal 100 transmits a Set-Printer-Attributes command (hereinafter referred to as "SPA") according to the IPP to the printer 10. SPA is a command that requests the printer 10 to register preset data. The SPA includes the user name UN and the preset data PD1 generated by T38.

When the printer 10 receives the SPA from the terminal 100 at the T40, the printer 10 compares the reference data 42 with the preset data in the SPA at the T42 and executes a comparison process for determining the information in the difference data.

In the initial state of FIG. 3, the reference data 42 includes the number of copies “1” corresponding to the identification number “1” and the number of colors “monochrome” corresponding to the identification number “2” (see FIG. 1). Further, as described above, the preset data PD1 includes the number of copies "1" and the number of colors "monochrome". That is, there is no difference between the reference data 42 and the preset data PD1. Therefore, the difference data D1 stored in T44, which will be described later, includes the difference flag “NO” for each of the identification numbers “1” and “2”, and has a value for each of the identification numbers “1” and “2”. Is not included (see FIG. 1). A specific case where there is a difference between the reference data 42 and the preset data PD1 will be described later with reference to FIG. In addition, the number of setting items of the preset data PD1 may be larger than the number of setting items of the reference data 42. This case will be described later in FIG.

In T44, the printer 10 generates the difference data D1 including the information determined in T42, and stores the preset information including the preset name “Preset1”, the user name UN, and the difference data D1 in the preset table 44.

At T46, the printer 10 transmits a registration completion notification indicating that the preset data identified by the preset name “Preset1” has been registered in the printer 10 to the terminal 100.

(Case A1; Fig. 4)
Case A1 shows a case in which the SPA including the preset data PD2 is received and the preset data PD2 is registered after the preset data PD1 is registered in FIG.

As shown in FIG. 4, the preset data PD2 includes two setting values corresponding to the two setting items. Specifically, the preset data PD2 includes the number of copies "10" and the number of colors "monochrome".

Further, the reference data 42 includes the number of copies "1" and the number of colors "monochrome" as in the initial state of FIG.

In the comparison process of this case (see T42 in FIG. 3), in the printer 10, the setting item "number of copies" of the identification number "1" is different from "1" in the reference data 42 and "10" in the preset data PD2. The difference flag corresponding to the setting item "number of copies" is determined to be "YES", and it is determined to include the difference flag "YES" and the set value "10" in the preset data PD2 as the difference data D2. .. Subsequently, the printer 10 determines that the setting item "color number" of the identification number "2" is the same as "monochrome" in the reference data 42 and "monochrome" in the preset data PD2, and determines that the setting item "color" is the same. It is determined that the difference flag "NO" corresponding to "number" is included, the difference flag "NO" is included as the difference data D2, and the set value "monochrome" in the preset data PD2 is not included. Then, the printer 10 generates difference data D2 including the information determined by the comparison process of this case, and presets the preset information including the preset name "Preset2" of the preset data PD2, the user name UN, and the difference data D2. Store in 44.

According to this case, the printer 10 can realize the registration of the preset data PD2 by storing the difference data D2 related to the difference between the reference data 42 and the preset data PD2 in the memory 34. Here, the difference data D2 includes a setting value "10" having a difference from the reference data 42 with respect to the setting item "number of copies", but has a difference from the reference data 42 with respect to the setting item "number of colors". Does not include the setting value "monochrome". For example, without using the reference data 42, all of the two setting values (that is, the number of copies "10" and the number of colors "monochrome") corresponding to the two setting items included in the preset data PD2 are stored in the memory 34. A comparative example is assumed. In this comparative example, four set values (that is, a set value of two copies and a set value of two colors) are stored in the memory 34. On the other hand, according to this embodiment, when one preset data is newly registered in addition to the reference data, two setting values of the reference data 42 and one setting of the preset data PD2 having a difference are set. The value is stored in the memory 34, and the set value of the preset data PD1 having no difference is not stored in the memory 34. That is, in this embodiment, when one preset data is newly registered in addition to the reference data, three set values are stored in the memory 34. Therefore, in the configuration of this embodiment, the data size stored in the memory 34 can be compressed as compared with the above comparative example. Then, as the number of registered preset data increases, the data size stored in the memory 34 can be further compressed as compared with the comparative example.

(Case A2; Fig. 5)
Case A2 shows a continuation of case A1. In this case, the SPA including the preset data PD3 is received and the preset data PD3 is registered.

As shown in FIG. 5, the preset data PD3 includes four setting values corresponding to the four setting items. Specifically, the preset data PD3 includes the number of copies "1", the number of colors "color", the printing surface "double-sided long edge binding", and the image quality "4".

Further, the reference data 42 includes the number of copies "1" and the number of colors "monochrome" as in the initial state of FIG. That is, as shown in FIG. 5, the reference data 42 has two setting values corresponding to two setting items (that is, “number of copies” and “number of colors”) out of the four setting items of the preset data PD3. And does not include the two setting values corresponding to the other two setting items (that is, "printing surface" and "image quality"). That is, in this case, the number of setting items of the preset data PD3 is larger than the number of setting items of the reference data 42.

As the number of setting items of the reference data 42 increases, the data size of the reference data 42 increases. Since the number of setting items of the initial reference data 42 is small, the data size of the reference data 42 stored in advance in the memory 34 of the printer 10 can be compressed.

The printer 10 expands the reference data 42 when preset data having more setting items than the number of setting items of the reference data 42 is received. Specifically, the printer 10 specifies an item name (that is, an Attribute Name) of a setting item that is not included in the reference data 42 from the preset data PD3. In this case, the printer 10 specifies the item name "printing surface" and the item name "image quality" that are not included in the reference data 42. The printer 10 adds the item name "printing surface" and the set value "double-sided long edge binding" of the preset data PD3 to the reference data 42 in association with the new identification number "3", and further adds the item name "double-sided long edge binding" to the new identification number "4". In association with this, the item name "image quality" and the preset data PD3 setting value "4" are added to the reference data 42. As a result, the reference data 42 is expanded from two setting items to four setting items.

In the comparison process of this case (see T42 in FIG. 3), the printer 10 compares the expanded reference data 42 with the preset data PD3. Specifically, in the printer 10, the setting value in the reference data 42 and the setting value in the preset data PD3 are the same for each of the setting items "number of copies", "printing surface", and "image quality", so that the difference flag Is determined to be "NO", and it is determined not to include the three set values "1", "double-sided long side binding", and "4" in the preset data PD3 as the difference data D3. Further, the printer 10 determines the difference flag to "YES" because the setting value in the reference data 42 and the setting value in the preset data PD3 are different for the setting item "number of colors", and the preset data PD3 is set as the difference data D3. It is decided to include one of the setting values "color". Then, the printer 10 generates the difference data D3 including the information determined by the comparison process of this case, and presets the preset information including the preset name "Preset3" of the preset data PD3, the user name UN, and the difference data D3. Store in 44.

(Case A3; Fig. 6)
Case A3 shows a continuation of case A2. In this case, the SPA including the preset data PD4 is received and the preset data PD4 is registered.

As shown in FIG. 6, the preset data PD4 includes four setting values corresponding to the same four setting items as the expanded reference data 42. Specifically, the preset data PD4 includes the number of copies "1", the number of colors "color", the printing surface "double-sided long edge binding", and the image quality "3".

In the comparison process of this case (see T42 in FIG. 3), the printer 10 compares the expanded reference data 42 with the preset data PD4. Specifically, in the printer 10, the printer 10 has the same set value in the reference data 42 and the set value in the preset data PD4 for each of the two setting items "number of copies" and "printing surface". , The difference flag is set to "NO", and it is decided not to include the two set values "1" and "double-sided long side binding" in the preset data PD4 as the difference data D4. Further, the printer 10 determines the difference flag to "YES" because the setting value in the reference data 42 and the setting value in the preset data PD4 are different for the two setting items "color number" and "image quality". It is determined to include the two set values "color" and "3" in the preset data PD4 as the difference data D4. Then, the printer 10 generates difference data D4 including the information determined by the comparison process of this case, and presets the preset information including the preset name "Preset4" of the preset data PD4, the user name UN, and the difference data D4. Store in 44.

For example, when preset data having more setting items than the number of setting items of the reference data 42 is received, a comparative example in which the reference data 42 is not expanded is assumed. In this comparative example, the data size can be compressed for the same setting items as the setting items included in the reference data 42, but the setting items different from the setting items included in the reference data 42 can be compressed as described above. It is necessary to store the setting value corresponding to the setting item included in the preset data in the memory 34. On the other hand, according to the case A3 of FIG. 6, for the setting item "printing surface" different from the setting item included in the reference data 42 before expansion, the setting value "double-sided long edge binding" included in the preset data PD4. Does not have to be stored in the memory 34. According to this case, the data size stored in the memory 34 can be further compressed as compared with the comparative example in which the reference data 42 is not expanded. In the modified example, the above comparative example may be adopted.

(Case A4; Fig. 7)
Case A4 shows a continuation of case A3. In this case, the SPA including the preset data PD5 is received and the preset data PD5 is registered.

As shown in FIG. 7, the preset data PD5 has less setting items than the number of setting items of the expanded reference data 42. Specifically, the preset data PD5 includes the number of copies "1", the number of colors "color", and the image quality "4", and does not include the setting value corresponding to the setting item "printing surface".

In the comparison process of this case (see T42 in FIG. 3), the printer 10 compares the expanded reference data 42 with the preset data PD5. Specifically, in the printer 10, the printer 10 has the same set value in the reference data 42 and the set value in the preset data PD5 for each of the two setting items "number of copies" and "image quality". It is determined that the difference flag is set to "NO" and that the difference data D5 does not include the two set values "1" and "4" in the preset data PD5. Further, since the setting value in the reference data 42 and the setting value in the preset data PD5 are different for one setting item "color number", the printer 10 determines the difference flag to "YES" and sets it as the difference data D5. It is decided to include the two setting values "color" in the preset data PD5. Further, in the printer 10, since the preset data PD5 does not include the setting value corresponding to the setting item "printing surface" for one setting item "printing surface", the setting value and the difference corresponding to the setting item "printing surface". Decide not to include the flag in the difference data D5. Then, the printer 10 generates the difference data D5 including the information determined by the comparison process of this case, and presets the preset information including the preset name "Preset 5" of the preset data PD5, the user name UN, and the difference data D5. Store in 44.

(Printing; Fig. 8)
Printing using preset data will be described with reference to FIG. 7. This case is a continuation of FIG. In the initial state of this case, five preset information, which is a material for generating the five preset data PD1 to PD5, is stored in the preset table 44.

T100 to T122 are the same as T10 to T22 in FIG. In T124, the printer 10 generates (that is, restores) five preset data PD1 to PD5. First, the printer 10 identifies five preset informations associated with the user name UN from the preset table 44. Then, the printer 10 uses the five specified preset information to generate preset data PD1 to PD5.

For example, the preset data PD2 is restored as follows using the difference data D2 (see FIG. 4). First, the printer 10 selects the identification number "1" in the difference data D2. The printer 10 determines that the difference flag corresponding to the identification number "1" of the difference data D2 indicates "YES". In this case, the printer 10 combines the item name "copies" corresponding to the identification number "1" of the reference data 42 and the set value "10" corresponding to the identification number "1" of the difference data D2. Then, the data about the setting item "number of copies" in the preset data PD2 is restored. Next, the printer 10 selects the identification number "2" in the difference data D2. The printer 10 determines that the difference flag corresponding to the identification number "2" of the difference data D2 indicates "NO". In this case, the printer 10 sets the item name "print-color-mode" and the setting value "monochrome" corresponding to the identification number "2" of the reference data 42 in the preset data PD2. Adopted as data about "number of colors". As a result, the preset data PD2 is restored. The preset data PD1 and PD3 to PD5 are also restored in the same manner.

T126 is similar to T26 in FIG. 3 except that the capability response includes preset data PD1 to PD5. T130 is the same as T30.

In this case, the list in the preset screen includes preset names "Preset1" to "Preset5" corresponding to the preset data PD1 to PD5. The user selects the preset name "Preset2" from the list in the preset screen. In this case, the terminal 100 displays a print screen including a "Print" button that receives an instruction to execute printing. The print screen further includes the number of copies "10" and the number of colors "monochrome" indicated by the preset data PD2 of the preset name "Preset2". As a result, the user can confirm the set value registered as the preset name "Preset2".

At T140, the terminal 100 accepts the selection of the "Print" button on the print screen. At T150, the terminal 100 transmits a print execution request requesting printing of the image to be printed to the printer 10. The print execution request includes a user name UN, two set values (that is, the number of copies "10" and the number of colors "monochrome"), and image data corresponding to the image to be printed.

When the printer 10 receives the print execution request from the terminal 100 in the T150, the printer 10 prints the image corresponding to the image data included in the print execution request according to the two set values included in the print execution request. To execute.

(Second Example)
This embodiment is the same as that of the first embodiment except that the difference data is different from the reference data 42.

(Reference data; Fig. 9)
The reference data 42 includes K1 data corresponding to K1 setting items (K1 is an integer of 1 or more) and K2 data corresponding to K2 setting items (K2 is an integer of 1 or more). ,including. Here, for each of the K1 setting items, the setting value corresponding to the setting item has the mode of the first kind. The first aspect is one of the Attribute Syntax "text", "octetString", "name" and "keyword". On the other hand, for each of the K2 setting items, the setting value corresponding to the setting item has the second type mode. The second aspect is one of the Attribute Syntax "integer", "enum" and "boolean".

Further, each of the K1 data corresponding to the K1 setting item includes an identification number, an item name, and a set value, as in the first embodiment. For example, as shown in FIG. 9, one of the K1 data includes the identification number “2”, the item name “printing surface”, and the set value “monochrome”. On the other hand, each of the K2 data corresponding to the K2 setting items includes the identification number and the item name, and does not include the set value. For example, as shown in FIG. 9, one of the K2 data includes the identification number “1” and the item name “number of copies”, and does not include the set value.

(Case B1; Fig. 9)
A specific case B1 in which the SPA including the preset data PD6 is received and the preset data PD6 is registered will be described with reference to FIG.

As shown in FIG. 9, the preset data PD6 includes three setting values corresponding to the three setting items. Specifically, the preset data PD6 includes the number of copies "10", the number of colors "monochrome", and the printing surface "single side".

When the SPA including the preset data PD6 is received from the terminal 100 (see T40 in FIG. 3), the printer 10 executes a process different from that of the first embodiment and stores the difference data D6 in the preset table 44. .. In this process, the printer 10 executes the first process when the set value corresponding to the setting item has the mode of the first type, and when the set value corresponding to the setting item has the mode of the second type. In addition, a second process different from the first process is executed. Specifically, first, the printer 10 determines that the setting value corresponding to the setting item "number of copies" of the identification number "1" has the second type mode (that is, "integer"). The second process of determining that the difference data D6 does not include the difference flag and includes the set value “10” in the preset data PD6 is executed. Subsequently, the printer 10 determines that the setting value corresponding to the setting item "color number" of the identification number "2" has the first type mode (that is, "keyword"), and the reference data 42 Judging that "monochrome" in the preset data PD6 is the same as "monochrome" in the preset data PD6, the difference flag corresponding to the setting item "number of copies" is determined to be "NO", and the difference flag "NO" is set as the difference data D6. The first process of determining not to include the set value "monochrome" in the preset data PD6 is executed. Subsequently, the printer 10 determines that the setting value corresponding to the setting item "printing surface" of the identification number "3" has the first type mode (that is, "keyword"), and the reference data 42 Judging that the "double-sided long-side binding" in the preset data PD6 is different from the "single-sided" in the preset data PD6, the difference flag corresponding to the setting item "printing surface" is determined to be "YES", and the difference flag "YES" is set as the difference data D6. "And the first process of determining to include the set value" one side "in the preset data PD6 is executed. Then, the printer 10 generates the difference data D6 including the information determined in the first process and the second process of this case, and the preset name “Preset 5” of the preset data PD6, the user name UN, and the difference data D6 The preset information including the above is stored in the preset table 44. That is, in the first aspect, the comparison process of the first embodiment (that is, the set value is stored as the difference data when the difference flag “NO” is determined, and is set when the difference flag “YES” is determined. The first process similar to the process of not storing the value as the difference data (see T42 in FIG. 3) is executed. On the other hand, in the second aspect, the set value in the reference data 42 and the set value in the preset data are not compared, and the value of the difference flag is not determined. That is, the second process does not include the comparison process.

As described above, the maximum length of the first aspect is longer than the maximum length of the second aspect. For example, the first situation in which the L set values having the first aspect are stored in the memory 34 and the second situation in which the L set values having the second aspect are stored in the memory 34 are compared. .. The difference between the data size in the first situation and the data size in the second situation increases as the number L increases. In the first aspect in which the data size becomes relatively large when a large number of set values are stored, the data size stored in the memory 34 is stored by executing the first process similar to the comparison process of the first embodiment. To compress. On the other hand, in the second type mode in which the data size does not become relatively large even if a large number of set values are stored, a large number of set values are stored as they are without executing the comparison process. That is, even if the comparison process is executed for the second type mode in which the data size does not become relatively large even if a large number of set values are stored, the data size cannot be expected to be compressed as compared with the first type mode. It is possible to suppress the execution of the comparison process in the second type mode in which the data size cannot be expected to be compressed.

Further, when the GPA is received from the terminal 100 (see T120 in FIG. 8), the printer 10 executes a process different from that of the first embodiment to restore the preset data PD6. In this process, the printer 10 executes the third process when the identification number indicating the setting item corresponding to the set value having the first type mode is selected, and the printer 10 executes the third process, and the set value having the second type mode. When the identification number indicating the setting item corresponding to is selected, the fourth process different from the third process is executed (see FIG. 9). Specifically, the printer 10 selects the identification number "1". Since the setting value corresponding to the setting item "number of copies" indicated by the identification number "1" has the second type mode in the printer 10, the item name "copies" corresponding to the identification number "1" and the item name "copies" are used. In combination with the setting value "10" corresponding to the identification number "1" of the difference data D6, the fourth process of restoring the data regarding the setting item "number of copies" in the preset data PD6 is executed. Subsequently, the printer 10 selects the identification number "2". Since the setting value corresponding to the setting item "color number" indicated by the identification number "2" has the first aspect of the printer 10, the difference flag corresponding to the identification number "2" of the difference data D6 is "YES". Is determined. In this case, the printer 10 determines that the difference flag indicates "NO", and determines that the item name "print-color-mode" corresponding to the identification number "2" of the reference data 42 and the set value "monochrome". (Monochrome) ”is used as the data for the setting item“ number of colors ”in the preset data PD6, and the third process is executed. Subsequently, the printer 10 selects the identification number "3". Since the setting value corresponding to the setting item "printing surface" indicated by the identification number "3" has the first aspect of the printer 10, the difference flag corresponding to the identification number "3" of the difference data D6 is "YES". Is determined. In this case, the printer 10 determines that the difference flag indicates "YES", and the item name "printed surfaces (sides)" corresponding to the identification number "3" of the reference data 42 and the identification number "sides" of the difference data D6. In combination with the setting value "one-side" corresponding to "3", the third process of restoring the data about the setting item "print side" in the preset data PD6 is executed. As a result, the preset data PD6 is restored.

As described above, in the third process in the first type aspect, the determination of whether or not the difference flag indicates "YES" is executed, but in the fourth process in the second type aspect, the process is concerned. Is not executed. Therefore, the processing load of the CPU 32 that executes the process for restoring the preset data can be reduced as compared with the first embodiment in which the determination is executed for all the setting items.

(Case B2; FIG. 10)
Case B2 shows a continuation of Case B1. In this case, the SPA including the preset data PD7 is received, and the preset data PD7 is registered.

As shown in FIG. 10, the preset data PD7 includes five setting values corresponding to the five setting items. Specifically, the preset data PD7 includes the number of copies "1", the number of colors "color", the printing surface "double-sided long edge binding", the image quality "4", and the printing medium "A4". That is, in this case, the number of setting items of the preset data PD7 is larger than the number of setting items of the reference data 42.

The printer 10 expands the reference data 42 when preset data having more setting items than the number of setting items of the reference data 42 is received. Specifically, the printer 10 specifies an item name (that is, an Attribute Name) that is not included in the reference data 42 from the preset data PD7. In this case, the printer 10 specifies the item name "image quality" and the item name "print medium" that are not included in the reference data 42. The printer 10 selects the item name "image quality" from the two specified item names. The printer 10 determines that the set value corresponding to the item name "image quality" has the second type mode (that is, "enum"), associates it with the new identification number "4", and uses the item name "image quality" as reference data. It is added to 42, and the set value "4" in the preset data PD7 is not added to the reference data 42. Next, the printer 10 selects the item name "printing medium" from the two specified item names. The printer 10 determines that the set value corresponding to the item name "print medium" has the first type mode (that is, "keyword"), and associates the setting value with the new identification number "5" with the item name "print medium". The set value "A4" in the preset data PD7 is added to the reference data 42. As a result, the reference data 42 is expanded from three set values to five set values.

In this case, the printer 10 executes the first process and the second process described above by using the expanded reference data 42, and stores the difference data D7 in the preset table 44. Details will be omitted.

For example, even when the item name not included in the reference data 42 has the second type mode, a comparative example in which the set value in the preset data PD7 is added to the reference data 42 is assumed. In this comparative example, unnecessary set values that are not used in the second process in the second aspect are added to the reference data 42. On the other hand, in this case, unnecessary setting values that are not used in the second process in the second aspect are not added to the reference data 42. It is possible to prevent the data size of the expanded reference data 42 from becoming unnecessarily large. In the modified example, the configuration of the above comparative example may be adopted.

(Third Example)
This embodiment is the same as that of the first embodiment except that the reference data 42 is different and the material data is stored in the preset table 44.

(Reference data; Fig. 11)
The reference data 42 includes, for each of the plurality of setting items, an identification number for identifying the setting item and an item name (that is, Attribute Name) indicating the setting item, and includes a value corresponding to the setting item. No. For example, as shown in FIG. 11, in the reference data 42, the item name "copies" corresponding to the identification number "1" and the item name "color-number (print-color-)" corresponding to the identification number "2" are used. mode) ”, including.

(Case C1; FIG. 11)
A specific case C1 in which the SPA including the preset data PD8 is received and the preset data PD8 is registered will be described with reference to FIG.

As shown in FIG. 11, the preset data PD8 includes two setting values corresponding to the two setting items. Specifically, the preset data PD8 includes the number of copies "1" and the number of colors "color".

When the SPA including the preset data PD8 is received from the terminal 100 (see T40 in FIG. 3), the printer 10 executes a process different from that of the first embodiment and stores the difference data D8 in the preset table 44. .. Specifically, first, the printer 10 uses a combination of the identification number "1" and the set value "1" in the preset data PD8 as the material data MD for the setting item "number of copies" of the identification number "1" as a preset table. Store in 44. Subsequently, the printer 10 stores the combination of the identification number "2" and the set value "color" in the preset data PD8 in the preset table 44 as the material data MD for the setting item "color number" of the identification number "2". do. Then, the printer 10 stores the preset information including the preset name “Preset 8” of the preset data PD8, the user name UN, and the material data MD in the preset table 44.

Further, when the GPA is received from the terminal 100 (see T120 in FIG. 8), the printer 10 executes a process different from that of the first embodiment to restore the preset data PD8. Specifically, the printer 10 selects the identification number "1". The printer 10 combines the item name "copies" corresponding to the identification number "1" and the set value "1" corresponding to the identification number "1" of the material data MD to be included in the preset data PD8. Restore the data for the setting item "Number of copies". Subsequently, the printer 10 selects the identification number "2". The printer 10 combines preset data by combining the item name "print-color-mode" corresponding to the identification number "2" and the set value "color" corresponding to the identification number "2" of the material data MD. Restore the data about the setting item "number of colors" in PD8. As a result, the preset data PD8 is restored.

According to this case, the printer 10 can realize the registration of the preset data PD8 by storing the material data MD, which is a material for generating the preset data PD8, in the memory 34. Here, the preset data PD8 includes an item name (that is, Attribute Name) and a set value (that is, Attribute Value). On the other hand, the material data MD includes an identification number and a set value. For example, a comparative example is assumed in which the combination of the item name and the set value is stored in the memory 34 as material data without using the identification number. In this comparative example, when three preset data are registered, the same three item names are stored in the memory 34 as material data. On the other hand, according to the present embodiment, when three preset data are registered, one item name is stored in the memory 34 as the reference data 42, and the four identification numbers are the reference data 42 and the material data MD. Is stored in the memory 34. Here, an integer shorter than the character string representing the item name is adopted as the identification number. Therefore, as the length of the identification number becomes shorter than the length of the item name, the data size stored in the memory 34 can be compressed as compared with the above comparative example. Further, the more preset data is registered, the more the data size stored in the memory 34 can be compressed as compared with the above comparative example.

In the first and second embodiments, as in the third embodiment, an identification number shorter than the item name is used. In the first and second embodiments as well, the data size stored in the memory 34 can be compressed as in the third embodiment.

The identification number and the Attribute Name are examples of the "identifier" and the "item name", respectively. The material data MD is an example of "material data".

Although specific examples of the present invention have been described in detail above, these are merely examples and do not limit the scope of claims. The techniques described in the claims include various modifications and modifications of the specific examples illustrated above. Modifications of the above embodiment are listed below.

(Modification 1) The "image processing" is not limited to the printing processing, and may be, for example, a scanning processing. In this case, the "setting data" includes a plurality of setting values corresponding to a plurality of setting items (for example, image quality, data format, size, etc.) for executing the scanning process.

(Modification 2) In each of the above embodiments, the printer 10 stores the difference data when the SPA according to the IPP is received from the terminal 100 (T40 in FIG. 3). Instead, the printer 10 may function as a web server, and when receiving an HTTP request from the terminal 100, may transmit screen data corresponding to the registration screen for registering preset data to the terminal 100. .. When a plurality of setting values are input on the registration screen, the printer 10 may receive an HTTP command including the plurality of setting values from the terminal 100. Then, the printer 10 may generate and store the difference data from a plurality of set values in the HTTP command. In this modification, the HTTP command is an example of a "first registration request (or second registration request)".

(Modification 3) In the first embodiment, the process of case A2 of FIG. 5 may not be executed. Further, in the second embodiment, the process of case B2 of FIG. 10 may not be executed. In this modification, the "additional part" can be omitted.

(Modification 4) In the above second embodiment, any one of Attribute Syntax "text", "octetString", "name" and "keyword" is an example of "aspect of the first kind", and Attribute. Any one of Syntax "integer", "enum" and "boolean" is an example of "aspect of the second kind". Instead, the "first type mode" is a mode in which the length of the set value is longer than a predetermined length (for example, 10 octets), and the "second type mode" is the length of the set value. May be an embodiment having a length equal to or less than the predetermined length.

(Modification 5) In the first embodiment described above, the difference data may store an item name (that is, an Attribute Name) instead of the identification number. In this modification, the "identifier" can be omitted.

(Modification 6) In each of the above embodiments, the reference data 42 is stored in the memory 34 in advance at the shipping stage of the printer 10. Instead, the reference data 42 may be generated by using the preset data included in the SPA when the SPA is received from the terminal 100 for the first time. In this modification, the preset data included in the SPA received from the terminal 100 for the first time is an example of "specific setting data".

(Modification 7) The reference data 42 is not limited to the one containing the Attribute Value and not including the Length of Attribute Value (see FIG. 1 etc.), for example, in addition to the Attribute Value, the Length of Attribute Value and the Length of Attribute. It may contain at least one of the Names. Along with this, the difference data may also include at least one of the Length of Attribute Value and the Length of Attribute Name in addition to the Attribute Value.

For example, the reference data 42 may include an Attribute Value and a Length of Attribute Value. Then, the printer 10 compares the information in the reference data 42 (that is, Attribute Value and Length of Attribute Value) with the information in the preset data (that is, Attribute Value and Length of Attribute Value), and determines the difference between the two information. The indicated information may be stored as difference data. For example, when the Attribute Syntax is "octetString", the Length of Attribute Value of the preset data can be restored by using the Length of Attribute Value included in both the reference data 42 and the difference data. In this modification, Attribute Value and Length of Attribute Value are examples of "values".

Further, for example, the reference data 42 and the difference data may include the Attribute Value and may not include the Length of Attribute Value when the Attribute Syntax is the first type syntax (for example, “integer”). Attribute Value and Length of Attribute Value may be included in the case of the second type syntax (for example, "octetString").

(Modification 8) In each of the above embodiments, the processes of FIGS. 4 to 11 are realized by software (for example, program 40), but at least one of these processes is performed by hardware such as a logic circuit. It may be realized.

In addition, the technical elements described in the present specification or the drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the techniques illustrated in the present specification or drawings achieve a plurality of objectives at the same time, and achieving one of the objectives itself has technical usefulness.
