Description

  The present invention relates to a printing system, a network interface device, a printing device, a data providing method, and a storage medium, and in particular, a printing system, a network interface device, a printing device, and data suitable for distributing and disposing web contents (information contents). The present invention relates to a providing method and a storage medium.

  In recent years, with the widespread use of the Internet, a form in which a printing apparatus is used in a network has become common. Usually, high-speed machines such as high-speed machines and color machines tend to have a built-in network interface, but in the case of a low-cost monochrome machine, the network interface is not included in the main unit. A form supplied separately as a network card module is common.

  In this case, the printing apparatus main body and the network card module are intelligent forms each having a CPU, and each module implements a desired service by communicating between connection interfaces. On the contrary, this makes it possible to drive out a heavy network service to the network card module, relatively lowering the CPU and peripheral performance of the printing apparatus main body, and reducing the cost of the printing apparatus main body. Yes.

  The conventional network interface only needs to be able to transmit print data represented by, for example, lpr. However, recently, there is a growing need for information management for printing apparatuses, and various means are provided as additional techniques.

  The simplest example is a form in which information management data (job control language = Job Language) is added to a port for transmitting print data. The job control language is a form that shares the port to send print data, so it is not necessary to increase the service port and it is relatively easy to implement. However, if a large amount of data is sent during print data reception, the port In the case of a one-way connection such as the lpr protocol in the network, there is a disadvantage that information cannot be acquired in the first place.

  As a next method, there is a method using Simple Network Management Protocol (SNMP) / Management Information Base (MIB). This is a method of using SNMP, which is a standard, using a dedicated port for data transmission / reception. However, this method requires original development of a dedicated client program that receives SNMP and provides a UI (User Interface), and since this method is a simple protocol for exchanging information in the first place, It can only provide simple databases such as strings. As a result, there is a problem that the information that configures the UI, such as a bitmap image showing the configuration of the device, must be owned by the client program, and the client program must correspond to the model accordingly.

  The latest method is to provide HTTP (Hyper Text Transfer Protocol) service in the network card module to provide WEB contents such as HTML (Hyper Text Markup Language) data and bitmap images related to device information. If the WEB content is displayed on a GUI (Graphical User Interface) using a general WEB browser and can be operated, the same effect can be obtained without providing a client program. In the conventional method, it is necessary for the client program to manage information (message character strings, bitmap images) unique to a wide variety of devices. It is the most suitable way to provide products with.

  However, the above-described prior art has the following problems. That is, since the HTTP service described above is a function of the network, it is a function that is basically implemented on the network card module in order to share the basic module that configures the interface and the network protocol. However, the network card module is usually designed to be connected to a plurality of models of printing apparatuses in order to reduce development costs by sharing and product costs by mass production.

  However, since the models of multiple models of printers have messages and information specific to each model individually, in order to support all the unique information with the network card module, all printers This unique information must be stored in the network card module, which increases the cost due to the increase in ROM capacity.

  Furthermore, in order to correspond to the specific information of the printing device that will be released after the network card module is announced as a product, the firmware of the network card module must be rewritten each time, and maintenance work is required. Will occur and the cost will increase.

  In particular, the present invention provides a printing system, a network interface device, a printing device, a data providing method, and a storage capable of providing WEB contents in a plurality of languages with a single network module even when the printing device is compatible with a plurality of countries. The purpose is to provide a medium.

  In order to achieve the above object, the present invention provides a printing system in which a printing device and a network module cooperate to provide a printing service to an external device on a network, and the network module is a destination of the printing device. Destination information acquisition means for acquiring information from the printing apparatus, providing means for providing the external apparatus with display data describing an operation screen for the external apparatus to remotely operate the printing system, and the external device If the data required for the screen requested from the device is device-dependent data dependent on the printing device, the device-dependent data is requested to the printing device, and the screen is requested from the external device. If the data is device-independent data that does not depend on the printing device, the device-independent data is entered from within the network module. Data acquisition means for acquiring data, and the providing means provides the display data to the external device based on the destination information of the printing apparatus acquired by the destination information acquisition means. Features.

  According to the present invention, the network module acquires destination information of the printing apparatus from the printing apparatus, and displays display data describing an operation screen for remotely operating the printing system based on the destination information to the external apparatus. provide. Thereby, even when the printing apparatus supports a plurality of countries, it becomes possible to provide WEB contents in a plurality of languages with a single network module.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[First Embodiment]
FIG. 1 is a block diagram showing a configuration example of a printing system according to the first embodiment of the present invention. The printing system according to the first embodiment includes a host computer 100, a printing apparatus 101 including a network card unit 110 and a printing unit 120, and Ethernet (registered trademark) (US) that connects the host computer 100 and the printing apparatus 101. And a predetermined communication medium 102 such as a LAN having a bus structure jointly developed by Xerox, DEC and Intel.

  Further, the network card unit 110 of the printing apparatus 101 includes a network I / F unit 111, an lpd server unit 112, a WWW (World Wide Web) server unit 113, a printing apparatus I / F unit 114, and a model-independent content unit 115. The printing unit 120 of the printing apparatus 101 includes a reception buffer 121, a model-dependent content unit 122, a PDL translator 123, an intermediate buffer 124, a drawing unit 125, a printer engine 126, and a network card I / F unit 127.

  In detail, in the network card unit 110 of the printing apparatus 101, the network I / F unit 111 communicates with the communication medium 102, and the data received via the communication medium 102 according to the service. Pass to the next stage. The lpd server unit 112 supports the Line Printer Daemon Protocol <RFC1179> and supports a print application based on the protocol defined by RFC1179, and receives print data transmitted from the host computer 100. The WWW server unit 113 transmits and receives the status of the printing apparatus 101 requested from the host computer 100 using HTTP. The printing apparatus I / F unit 114 instructs the printing unit 120 to receive print data and model-dependent content. The model-independent content unit 115 stores HTML content and bitmap content independent of the model in the WWW server unit 113.

  In the printing unit 120 of the printing apparatus 101, the network card I / F unit 127 communicates with the printing apparatus I / F unit 114, and passes data based on the communication to the next stage according to the service. The reception buffer 121 includes a RAM or an HDD device, receives print data, and passes it to the PDL translator 123. The model-dependent content unit 122 stores HTML content and bitmap content depending on the model. The PDL translator 123 takes out the print data stored in the reception buffer 121, analyzes PDL (Page Description Language), and converts it into intermediate data for rendering.

  The intermediate buffer 124 temporarily stores intermediate data converted by the PDL translator 123 and passes it to the drawing unit 125. The drawing unit 125 extracts intermediate data for drawing from the intermediate buffer 124, converts it into raster data, and passes it to the printer engine 126. The printer engine 126 prints the raster data converted by the drawing unit 125 by a known electrophotographic technique or ink-jet technique on paper and discharges it. Here, the printer engine unit 126 uses a known printing technique, and for example, an electrophotographic system or an inkjet system is generally used.

  FIG. 13 is a diagram illustrating an example in which HTML content or bitmap content provided by the WWW server unit 113 of the printing apparatus 101 is displayed on the display using the GUI of the WWW browser software of the host computer 100. In FIG. 13, the screen configuration is divided into two frames. That is, the mode switching frame 1301 and the mode display frame 1351.

  The mode switching frame 1301 is provided with buttons for prompting transition to each mode in order to display a screen divided into modes for a WWW service having many functions, and includes a device management 1302, a job management 1303, There are buttons for device management 1304 and support link 1305, respectively, indicating the transition to each mode.

  A mode display frame 1351 shows a device management status frame. From the top, a device bitmap icon 1352, a device name 1353, a status display 1354, a paper feeder (manual tray, upper cassette) 1355 indicating information on the lower cassette, paper deck, envelope feeder), 1356 indicating the status of the paper discharge device (discharge tray, bin 1, bin 2, bin 3), bitmap image 1357 indicating the configuration of the device, utility Button 1358 indicating activation of the device and a button 1359 indicating activation of device control.

  Next, content will be described. The reason why the printing apparatus 101 includes the WWW server unit 113 is that the WWW server unit 113 is used to view and operate the status monitoring, initial value setting, and print job control of the printing apparatus 101 using the WWW browser of the host computer 100. As the internal structure, the database operates as a database that provides WEB content requested from the host computer 100.

FIG. 2 is a diagram showing an example of basic HTML (HyperText Markup Language) notation. This notation is simplified for the sake of explanation, and actually more complicated documents are described. In FIG.
<! DOCTYPE HTML PUBLIC ”-// IETF // DTD HTML2.0 // EN”>
This line is a document type declaration in an SGML (Standard Generalized Markup Language) document, and indicates that the document is HTML.

  An HTML document is described in an area surrounded by <HTML> to </ HTML>.

  The area between <HEAD> and </ HEAD> indicates the header area of the HTML document, and the string “WEB Console Interface” enclosed in <TITLE> </ TITLE> is the subject of the document. Represents.

  An area surrounded by <BODY> to </ BODY> indicates the inside of the HTML document, and two images are captured therein.

  The first image is <IMG SRC = ”/ dev / device.png”>, and an overview of this image is shown in FIG. Since /dev/device.png is not represented by URL (Uniform Resource Locator), it can be understood that it is internal data of the printing apparatus 101. Further, /dev/device.png shows an overview of the printing apparatus 101, and it is understood that this is “model-dependent WEB content” depending on the model of the printing apparatus 101. If the printing device is different from the normal printing device, that is, if it is a color type printing device or a printing device with a different overview with a small number of paper cassettes, /dev/device.png Displays a different image.

  The second image is <IMC SRC = “/ nic / error.png”>, which is similarly not a URL notation, so that it is understood that it is internal data of the printing apparatus 101. Furthermore, /nic/error.png shows an abstract image that prompts cassette feeding, and it is understood that this is “model-independent WEB content” that does not depend on the model.

  As described above, the WEB content is roughly divided into a WEB content that depends on the model and a WEB content that does not depend on the model. Normally, the network card unit 110 of the printing apparatus 101 is required to support a plurality of models of the printing unit 120 with a single product, so that the web content depending on the model depends on the model in the printing unit 120. The model-dependent WEB content and the model-independent WEB content are stored separately, such as storing the WEB content that is stored in the content unit 122 and not dependent on the model in the model-independent content unit 115 in the network card unit 110. Furthermore, the WEB content stored in the model-dependent content unit 122 is stored separately according to the model. For example, in the case of device.png in FIG. 3, an overview corresponding to the model is stored as an image.

  Next, a description will be given of how the above-mentioned model-dependent WEB contents and model-independent WEB contents are separated and acquired. In the first embodiment, a path structure is used to distinguish the difference between the two. In the first embodiment, in the case of WEB content starting with / dev /, it is acquired from the model-dependent content unit 122 as model-dependent WEB content, and in the case of WEB content starting with / nic /, it is model-independent. WEB content is acquired from the model-independent content unit 115.

  FIG. 5 is a flowchart showing the operation of the WWW server unit 113 of the printing apparatus 101 according to the first embodiment of the present invention. The WWW server unit 113 is activated when the printing apparatus 101 is activated, and continues the service until the power is turned off. When the service is started, the WWW server unit 113 waits for a GET operation from the host computer 100 in step S501. The GET operation is an operation for requesting WEB content in HTTP, and loops to the head until this GET operation comes.

When a GET operation is received from the host computer 100, in step S502, the WWW server unit 113 checks the WEB content requested by the GET operation, and determines whether the WEB content is in URL notation. For example, the specified WEB content name is
http: //printer.domain/dev/device.html
In this case, since http: // is a scheme and printer.domain is a domain name, both are removed and only /dev/device.html is extracted.

  In step S504, the WWW server unit 113 checks whether or not the extracted WEB content name starts with / dev /. Since the WEB content (model-dependent WEB content) name starting with / dev / is a rule acquired from the printing unit 120 as described above, if the WEB content name starts with / dev /, in step S505, The WWW server unit 113 issues a web content acquisition request to the printing unit 120. In step S506, the printer 120 waits for a response from the printing unit 120. When a response is received from the printing unit 120, the requested web content is provided to the host computer 100 in the HTTP reply format in step S507.

  If the WWW server unit 113 determines in step S504 that the web content does not start with / dev / (model-independent web content), the web content is the web content owned by the network card unit 110. In step S508, the WEB content is acquired from the model-independent content unit 115, and the requested WEB content is provided to the host computer 100 in the HTTP reply format.

  That is, in the first embodiment, when the WWW server unit 113 performs a path check of the URL of the WEB content specified by the HTTP from the host computer 100, does the specified WEB content match a specific path? Based on whether or not, it is determined whether the specified WEB content is a model-dependent WEB content or a model-independent WEB content.

  When the WWW server unit 113 acquires WEB content starting with / dev / from the model-dependent content unit 122 in the printing unit 120, the WEB is transmitted via the printing apparatus I / F unit 114 and the network card I / F unit 127. Make a remote function call to load the content. The remote function call is a method for requesting file transfer from the network card unit 110 to the printing unit 120.

  FIG. 8 is a diagram showing a request packet format for instructing reading of web contents by a remote function call. In FIG. 8, a numerical value 100, which is a Remote Procedure Call ID indicating a request for reading web content, a number 0, indicating a request, a packet data size, and a path of the requested web content are transmitted in a bucket format. When the bucket is correctly interpreted by the network card I / F unit 127 of the printing unit 120, a response packet is transmitted.

  FIG. 9 is a diagram showing a response packet format for transmitting WEB content in response to a request packet for instructing reading of WEB content by a remote function call. In FIG. 9, a numerical value of 100 which is a remote procedure call ID indicating a web content reading request, a number of 1 indicating a response, a response state of 1 indicating that the reading was successful, the data size of the packet, and Binary data of WEB content is attached and transmitted. The WWW server unit 113 analyzes the response packet, extracts the WEB content, and transmits it to the host computer 100 using the HTTP protocol.

  The operation between the modules will be described with time. 6 and 7 are transition diagrams showing how WEB content requested from the host computer 100 is acquired between the modules. The vertical axis represents time, and shows changes in requests and responses between the host computer 100 and the network card unit 110 and the printing unit 120 of the printing apparatus 101.

  FIG. 6 shows the operation when “model-independent WEB content” is requested. Since the WEB content exists in the network card unit 110, the WEB content is extracted from the model-independent content unit 115 without transmitting a request to the printing unit 120 and transmitted to the host computer 100.

  FIG. 7 shows an operation when “model-dependent WEB content” is requested. Since the WEB content exists in the printing unit 120, a request is made to the printing unit 120, the WEB content is extracted from the model-dependent content unit 122 and transmitted to the host computer 100.

  As described above, according to the first embodiment of the present invention, WEB contents are classified into model-dependent WEB contents and model-independent WEB contents, and the model-dependent WEB contents are arranged in the printing unit 120. However, the following effects can be obtained by distributing the WEB content independent of the model, for example, in the network card unit 110.

  (1) For all models of the printing unit 120 that may be connected to the network card unit 110, it is not necessary to have the web content in the model-independent content unit 115 in the network card unit 110, and the network card unit 110 It is possible to reduce the capacity cost.

  (2) For the same reason as described above, the printing unit 120 connected to the network card unit 110 can cope with the specific information of the printing unit that will be developed in the future without replacing the ROM of the network card unit 110. It becomes possible to do.

  (3) From the standpoint of the printing unit 120, when a network card is not required, a WWW server unit 113 that transmits and receives the requested printing apparatus status using HTTP, and a model that stores model-independent web content By evicting the independent content unit 115 to the network card unit 110, it is possible to suppress an increase in cost.

[Second Embodiment]
In the first embodiment, whether the WEB content is a model-dependent WEB content or not based on whether the character string obtained by taking the path portion from the URL of the WEB content includes “/ dev /” or not. It was determined whether it was dependent WEB content. However, with this method, it is possible to infer whether the WEB content is a model-dependent WEB content or a model-independent WEB content by using the GUI of the host computer 100. Since the place where the WEB content is placed is internal information, it may not be preferable to make an analogy from the URL.

  Therefore, in the second embodiment of the present invention, as a measure for preventing the WEB content from being inferred from the URL, a character string obtained by taking a path portion from the WEB content URL as in the first embodiment. In this method, a character string list recognized as a model-dependent WEB content is prepared in advance, and the character string list is compared with the WEB content to be compared. is there.

  FIG. 10 is a block diagram showing a configuration example of a printing system according to the second embodiment of the present invention. The printing system according to the second embodiment includes a host computer 1000, a printing apparatus 1001 having a network card unit 1010 and a printing unit 1020, and a communication medium 1002 that connects the host computer 1000 and the printing apparatus 1001. ing.

  Further, the network card unit 1010 of the printing apparatus 1001 includes a network I / F unit 1011, an lpd server unit 1012, a WWW server unit 1013, a printing device I / F unit 1014, a model-independent content unit 1015, and a dependency list 1016. A printing unit 1020 of the printing apparatus 1001 includes a reception buffer 1021, a model-dependent content unit 1022, a PDL translator 1023, an intermediate buffer 1024, a drawing unit 1025, a printer engine 1026, and a network card I / F unit 1027.

  FIG. 10 is a partial modification of FIG. FIG. 10 is obtained by adding a dependency list 1016 to the network card unit of the printing apparatus in the configuration of FIG. 1 described above. The rest is the same, and the description of the same part is omitted.

  The dependency list 1016 provided in the network card unit 1010 of the printing apparatus 1001 is a database having a list of character strings. For example, if the dependency list 1016 has a list of character strings as shown in FIG. 11, the acquisition of the same WEB content as any of the character strings is requested to the printing unit 1020, and other WEBs are obtained. In the case of content, the network card unit 1010 provides it.

  FIG. 12 is a flowchart showing the operation of the WWW server unit 1013 of the printing apparatus 1001 according to the second embodiment of the present invention. FIG. 12 differs from FIG. 5 of the first embodiment in the comparison condition in step S1204. In step S1204, it is checked whether the specified path is included in the dependency list 1016. Accordingly, it is possible to set the WEB content as a model-dependent WEB content or a model-independent WEB content regardless of the URL or the path. Note that steps S1201 to S1203 and steps S1205 to S1207 in FIG. 12 are the same as steps S501 to S503 and steps S505 to S507 in FIG.

  As described above, according to the second embodiment of the present invention, a character string list recognized as a model-dependent WEB content is prepared, and the character string list is compared with the WEB content to be compared. Therefore, the WEB content can be set to a model-dependent WEB content or a model-independent WEB content regardless of the URL or the path.

[Third Embodiment]
In the second embodiment, the network card unit 1010 of the printing apparatus 1001 has the dependency list 1016.

  In contrast to this, as in the third embodiment of the present invention, the network card unit 1010 of the printing apparatus 1001 has a dependency list that is a character string list recognized as a device-dependent WEB content, instead of a device-independent list. You may make it provide the independent list | wrist which is a character string list recognized as WEB content. In the third embodiment, only the Yes / No in the comparison condition in step S1204 in FIG. 12 is switched, and the processing other than step S1204 is the same, and the same effect as in the second embodiment is obtained. be able to.

[Fourth Embodiment]
The printing system according to the fourth embodiment of the present invention includes a host computer 1000, a network I / F unit 1011, an lpd server unit 1012, a WWW server unit 1013, a printing apparatus I / F unit 1014, and a model-independent content unit. 1015, a network card unit 1010 having a dependency list 1016, a reception buffer 1021, a model-dependent content unit 1022, a PDL translator 1023, an intermediate buffer 1024, a drawing unit 1025, a printer engine 1026, and a printing unit 1020 having a network card I / F unit 1027 And a communication medium 1002 connecting the host computer 1000 and the printing apparatus 1001 (see FIG. 10 above).

  In FIG. 13, a bitmap image 1357 showing the device configuration of the printing apparatus 1001 is displayed when the user wants to display in accordance with the actual device configuration. The displayed image varies depending on the installation of optional equipment.

  Therefore, in the fourth embodiment of the present invention, the printer engine 1026 of the printing unit 1020 of the printing apparatus 1001 determines whether or not an optional device such as a paper feeding apparatus or a paper discharge apparatus is electrically connected to the printing apparatus 1001. Thus, the device configuration of the printing apparatus 1001 is specified, and the WWW server unit 1013 selects a bitmap image corresponding to the device configuration of the printing apparatus 1001 based on a single bitmap image transfer request from the host computer 1000. And transmitted to the host computer 1000.

  In the fourth embodiment of the present invention, a method of displaying a bitmap image 1357 corresponding to the device configuration will be described. FIG. 14 is a diagram showing a device configuration example when various optional devices are mounted in a certain device. The equipment is equipped with a standard cassette that can store 250 sheets of paper, for example, and can optionally store, for example, a cassette that can store 250 sheets of paper or can store 500 sheets of paper. A single cassette can be connected in one stage, and a double-sided device can be connected separately. In the double-sided device, in order to reverse the paper when printing on the front and back of the paper, it is necessary to sandwich the reversing device at the lower part of the double-sided device main body.

  In the above specifications, there are six possible combinations as device configurations, for example, as shown in the bitmap image of FIG. That is, a standard configuration (14-1) consisting only of equipment, a configuration (14-2) equipped with a cassette capable of storing 250 sheets of paper in the standard configuration (14-2), and a standard configuration capable of storing 500 sheets of paper, for example. A configuration (14-3) equipped with a single cassette, a configuration (14-4) equipped with a double-sided device in the standard configuration, and a single-stage cassette and a double-sided device capable of storing 250 sheets of paper in the standard configuration. The configuration (14-5) is equipped, and the standard configuration is a configuration (14-6) in which a cassette capable of storing 500 sheets of paper and a double-sided device are installed.

  Depending on the device (printing device), it is possible to add a paper discharge device in addition to the cassette and the double-sided device, and the number of combinations increases.

Therefore, it is possible to acquire a bitmap image corresponding to the device configuration determined by the printing unit 1020 only by inquiring about a single bitmap image.

[Fifth Embodiment]
The printing system according to the fifth embodiment of the present invention includes a host computer 1000, a network I / F unit 1011, an lpd server unit 1012, a WWW server unit 1013, a printing apparatus I / F unit 1014, and a model-independent content unit. 1015, a network card unit 1010 having a dependency list 1016, a reception buffer 1021, a model-dependent content unit 1022, a PDL translator 1023, an intermediate buffer 1024, a drawing unit 1025, a printer engine 1026, and a printing unit 1020 having a network card I / F unit 1027 And a communication medium 1002 connecting the host computer 1000 and the printing apparatus 1001 (see FIG. 10 above).

  In the fourth embodiment, a bitmap image suitable for the device configuration is selected from a plurality of bitmap images based on the device configuration content determined when the device is booted. Although automatic conversion based on the difference in the device configuration of the bitmap image is provided, the HTML content may also change depending on the device configuration.

  Therefore, in the fifth embodiment of the present invention, the printer engine 1026 of the printing unit 1020 of the printing apparatus 1001 determines whether or not an optional device such as a paper feeding apparatus or a paper discharge apparatus is electrically connected to the printing apparatus 1001. Thus, the device configuration of the printing apparatus 1001 is specified, and the WWW server unit 1013 performs parsing processing on the HTML requested to be transferred on the basis of a single HTML transfer request from the host computer 1000, and the internal SSI ( The device configuration is taken in as an interpretation condition of (Server Side Include), and different HTML is selected according to the device configuration and transmitted to the host computer 1000.

  In the fifth embodiment of the present invention, the case where the HTML content changes depending on the device configuration will be described with reference to the paper feed information 1355 shown in FIG. This paper feed information 1355 indicates paper feed information in a cassette connected to a device (printing apparatus), and the display contents differ depending on the device configuration at that time.

  For example, the example of the fourth embodiment described above will be described. If there is no optional cassette, the manual feed tray, two rows of the upper cassette, the 250-sheet cassette or the 500-sheet cassette, the manual feed tray, There are three rows, the upper cassette and the lower cassette. In order to switch the display, a method of expanding the SSI that is a function of the WWW server unit 1013 and returning paper feed information to the host computer 1000 according to the device configuration will be described.

  SSI is a technology that generally performs conversion processing (parsing processing) on WEB content acquired by a WWW server, converts text written in a specific format, and passes the converted result to the client. It is. One of the formats of SSI is a method of comparing the definition of a certain variable.

  Here, the conversion process means that the WWW server of the network card unit of the printing apparatus reads an HTML document (technically, an SHTML document) held by the printing apparatus, and a control statement described in the HTML document is read. This is a process of converting and generating an HTML document that can be analyzed by the browser of the host computer according to the configuration status of the printing apparatus.

  The format in the SSI format is as follows (line numbers are for explanation):

1: <! -# if expr = ”ENV = VALUEl”->
2: Syntax A
3: <! -# elif expr = ”ENV = VALUE2”->
4: Syntax B
5: <! -# else->
6: Syntax C
7: <! -# endif->
In the above 1 :, the contents of the environment variable ENV are examined, and when the value becomes VALUEl, syntax A is returned to the client. Otherwise, in step 3: above, this time the contents of the environment variable ENV are examined, and if the value is VALUE2, syntax B is returned to the client. Otherwise, syntax C is returned to the client.

  Here, when ENV is the special keyword “LOW-CASSETTE-EXIST”, the WWW server unit 1013 of the printing apparatus 1001 inquires of the model-dependent content unit 1022 of the printing unit 1020 whether the lower cassette exists. In this example, it is assumed that the state is acquired by a remote function call, but if there is a means for acquiring another model configuration means, it may be used (for example, a Jop control language interface or SNMP / MIB interface). ).

  As a result, if there is a lower cassette, the WWW server unit 1013 replaces the contents of “LOW-CASSETTE-EXIST” with TRUE.

WWW content
<! -# if expr = ”LOW-CASSETTE-EXIST = TURE”->
<HttIL notation for lower cassette>
<! -# endif->
Then, only when there is a lower cassette, it is possible to add HTML notation relating to the lower cassette and return it to the host computer 1000.

  This can be used not only in the paper feed information 1355 but also in the paper discharge information 1356.

  As described above, according to the fifth embodiment of the present invention, the host computer 1000 does not know the current device configuration of the printing unit 1020 of the printing apparatus 1001, and feeds information and the like from the printing apparatus 1001.
