To send packets. When the address of the device B matches the header 1411 of the packet 1410, the data 1412 is separated and reproduced to the state of the data that was in the device A.
[0093]
[Printer Driver]
Next, a process of transmitting image data to a printer from the computer 102 (or 103) by a printer driver will be described with reference to FIG. The printer driver is a GUI for instructing a print operation. By instructing the printer driver, the user can instruct a desired setting parameter and send a desired image to a transmission destination such as a printer.
[0094]
Reference numeral 1601 denotes a window of the printer driver, and 1602 denotes a transmission destination selection column for selecting a target output destination as a setting item in the window. Generally, it is similar to the above-described MFPs 104 and 105 or the printer 107, but an image may be transferred to the memory 108 for the purpose of storage. Reference numeral 1603 denotes a page setting column for selecting an output page from a job, and determines which page of an image created by application software operating on the computer 102 (or 103) to output. Reference numeral 1604 denotes a copy number setting column for designating the number of copies. Reference numeral 1607 denotes a property key for performing detailed settings related to the destination device selected in the destination selection column 1602. Clicking this button allows the user to enter setting information unique to the device on a separate screen and to display a special image. For example, by changing the parameters of the gamma conversion unit 707 and the spatial filter unit 708 in the CMYK-IP unit 207, finer color reproduction and sharpness adjustment can be performed.
[0095]
Reference numeral 1608 denotes finishing settings. The setting items differ depending on the selected printer.
[0096]
Clicking on the right of the destination selection column 1602 displays a list of printable printers, MFPs, and the like. To do so, it is necessary to search for printers on the network.
[0097]
When searching for MFPs and printers on the network, a so-called directory service is used. The directory service is, so to speak, a telephone directory relating to a network, and stores various information. As a specific example of the directory system using the directory service, there is, for example, an LDAP (Lightweight Directory Access Protocol).
[0098]
The above LDAP specification is described in RFC (Request For Communities) 1777 which is a standard specification issued by the IETF (Internet Engineering Task Force).
[0099]
By searching for a device connected to the network using the directory service, a list of network addresses of devices available on the network can be obtained. The computer 102 on the network 101 functions as an LDAP server, and stores all information on devices on the network. The computer can search for the desired device by inquiring the LDAP server instead of searching by itself.
[0100]
By registering the position information of the device in accordance with the information such as the equipment information and status of the device, it is possible to search for a device close to a computer or a printer closest to a desired printer and having a desired function.
[0101]
The position information defines, for example, the distance from the reference point in the X and Y directions and the floor information and the like as the Z direction.
[0102]
An example will be described with reference to FIG. 34. In this case, an arbitrary position on the first floor is set as a reference (hereinafter, a reference point).
[0103]
Since the MFP 104 is in the X direction 4 (a distance such as a fourth pillar or a distance unit of 40 m), the Y direction 3 and the floor is the second floor, the Z direction 2 is (4, 3, 2).
[0104]
Similarly, the MFP 105 is (1, 2, 3), the MFP 106 is (2, 3, 2), and the single-function printer 107 is (6, 3, 3).
[0105]
When weighting the floors, the same floor can be given priority by calculating by multiplying by a predetermined coefficient in the Z direction. Here, assuming that the coefficient in the Z direction is 10, the MFP 104 (4, 3, 20), the MFP 105 (1, 1, 20), the MFP 106 (2, 3, 20), and the single-function printer 107 (6, 3, 30) Become.
[0106]
The distance L between the two devices A (x1, y1, z1) and B (x2, y2, z2) is
L = | x1-x2 | + | y1-y2 | + | z1-z2 |.
[0107]
Here, the coefficient in the Z direction is 10. However, for example, since a certain place is close to a staircase or an elevator, by setting the coefficient to 3, it is possible to flexibly cope with the structure of the building.
[0108]
The driver can display a list of printers in the destination selection column 1602 by inquiring the LDAP server.
[0109]
Although a conventional printer driver cannot select two printers at the same time, this embodiment provides a key 1609 for selecting the next printer.
[0110]
By pressing this key, a further printer selection column 1609 is displayed, and the second printer or finisher can be selected.
[0111]
When another printer is selected, the user can press the property key 1607 to go to another setting screen and change the order of printer selection.
[0112]
When the right end of the printer selection column 1609 of the normal print driver is clicked on with a mouse, a list of selectable printers is displayed. At this time, as shown in FIG. 26, the printer appearing at the top of the list display can be changed according to various conditions.
[0113]
In FIG. 26, the printer list display conditions are such that the order close to the printer 1 is selected, the MFP 104 is selected by the transmission destination selection column 1602, and the key 1609 for selecting the next printer is turned on. Click the right edge of the with a mouse to display a list of printers that can be selected. As a display order, as a result of calculating the distance from the MFP 104, the display is performed in the order of the MFP 106, the MFP 105, and the single-function printer 107 in ascending order of the distance.
[0114]
This facilitates selection under the condition that the MFP is closest to the MFP selected first.
[0115]
If processing cannot be performed in the order of combination when two are selected, for example, punching cannot be performed after stapling, so a warning is displayed in that case.
[0116]
When the desired settings are completed, printing is started using the OK key 1605. In the case of canceling, the printing is canceled by the cancel key 1606.
[0117]
[Description of Network Utility Software]
Utility software that operates on the computer 102 (or 103) will be described.
[0118]
A standardized database called MIB (Management Information Base) is built in a network interface portion in the MFPs 104, 105, and 106 and the finisher 109, and a computer on a network through a network management protocol called SNMP (Simple Network Management Protocol). , And can manage MFPs 104 and 105 as well as scanners, printers, faxes, and the like connected on a network.
[0119]
On the other hand, a software program using MIB operates on the computer 102 (or 103), and necessary information can be exchanged using MIB by using the above SNMP via a network.
[0120]
By acquiring MIB information such as ifPhysAddress and sysObjectID defined by RFC1213 and hrDeviceID defined by RFC1514, it is possible to obtain information for specifying a device. Equipment information and capabilities of the apparatus are defined as the private MIB, and it is possible to detect whether or not a finisher is connected as equipment information.
[0121]
By acquiring MIB information, devices on the network can communicate with each other and acquire information such as the status and capabilities of the partner device.
[0122]
The computer 102 periodically communicates with the devices on the network, or keeps track of the functions, status, and the like of each device by transmitting from each device. Since the WEB server is constructed based on the MIB data collected from each device, the computer 103 can grasp the status of each device even if the computer 103 accesses the computer 102 using well-known HTTP-based browsing software.
[0123]
One end of the print job is thrown to the computer 102, and then the job is input from the computer 102 to each printer, and the user name, department, file name, number of pages, job contents, etc. of the job are analyzed, and the user unit and department are analyzed. The number of times of printing in units and the total number of pages are stored. In addition, it is possible to manage and operate devices and jobs on a network by totalizing the number of prints and errors of each device, the current remaining amount of paper and toner, and the like.
[0124]
Further, the computer 102 also converts the print protocol. For example, if the MFP 105 supports only LPD and tries to print from the computer 103 by IPP (Internet Printing Protocol), the computer 102 can automatically convert the data into LPR and throw a job to the MFP 105.
[0125]
The printed data is stored in the memory 108, and the server automatically deletes the data according to parameters such as the remaining amount of the memory and the date.
[0126]
[Description of GUI]
Next, a screen of utility software called a GUI (Graphic User Interface) that runs on the computer 102 (or 103) will be described with reference to FIGS.
[0127]
When the utility software is started on the computer 102 (or 103), a screen as shown in FIG. 16 is displayed. Reference numeral 1701 denotes a status tab for opening a status page, 1702 denotes a job tab for opening a page for operating a print job inside the printer, and 1703 denotes an information tab for opening a page for checking the equipment of the apparatus and the like. , 1704 are called network tabs for opening a page for making network settings.
[0128]
FIG. 16 shows a status page. Reference numeral 1705 denotes an external appearance image of the apparatus, on which an image corresponding to equipment information such as a finisher or a deck is displayed. On the right side, information on paper in each cassette is displayed as information on paper feed stages. Reference numeral 1706 denotes an operation state of the apparatus, which changes according to the operation state.
[0129]
FIG. 17 shows an information page, on which the presence or absence of a finisher, the presence or absence of a finisher option, and the like can be confirmed.
[0130]
[About add-ons]
Now, the addition of the add-on command will be described with reference to FIG.
[0131]
Although the original image 1801 is image data created by application software on the computer 102 (or 103), giving a command image to the image data will be described.
[0132]
The add-on information is, for example, an image pattern such as 1802, which is used to perform the paper ejection process created by the print driver when transferring image data created on a computer to the apparatus of the present embodiment. The information is used to read operation instructions such as staples, punches, inserts, etc., the number of pages, and the like by the finisher sensor 1009, and then the finisher operates the paper discharge process based on this information.
[0133]
[Additional pattern]
Next, FIGS. 19 to 23 are diagrams illustrating an example of an additional pattern according to the present embodiment.
[0134]
In FIG. 19, in the case of 200-line processing, 4 × 4 pixels included in the area 1901 are modulated so that the gradation of the image signal is, for example, + α, and 2 × 4 pixels included in the areas 1902 and 1903, respectively. Are modulated so that the gradation of the image signal is, for example, -α, and pixels other than the regions 1901 to 1903 are not modulated. Then, 8 × 4 pixels included in the regions 1901 to 1903 are set as unit dots of the additional pattern. In the case of 400 line processing, 4 × 4 pixel processing is performed. In the case of 100-line processing, 2 × 2 or one pixel is used as an additional pattern.
[0135]
Hereinafter, since the processing method is the same, an explanation will be given by taking 8 × 4 pixels as an example.
[0136]
FIGS. 20 and 21 are diagrams illustrating an example of the add-on line according to the present embodiment.
[0137]
In FIG. 20, reference numeral 2001 denotes an add-on line, for example, having a width of 4 pixels. Reference numerals 2001a to 2001e denote unit dots shown in FIG. 19, for example, 8 × 4 pixels. The unit dots 2001a to 2001e are arranged at a substantially constant period of d1 (for example, 128 pixels) in the main scanning direction.
[0138]
Further, in FIG. 21, reference numerals 2101 to 2110 are add-on lines having a width of, for example, 4 pixels, and are arranged at a substantially constant period of d2 (for example, 16 pixels) in the sub-scanning direction. As will be described later in detail, for example, one add-on line represents 4-bit information, and eight add-on lines 2102 to 2109 can be combined to represent 32-bit additional information. The add-on line is repeatedly formed in the sub-scanning direction. For example, add-on lines 2101 and 2109 shown in FIG. 21 represent the same information sequentially and repeatedly.
[0139]
FIG. 22 and FIG. 23 show an example of a method of expressing information by add-on-line. In FIG. 22, 2201 and 2202 are add-on lines, and both add-on lines are adjacent in the sub-scanning direction. In addition, 2201a, 2201b and 2202a are unit dots, and the adjacent add-online unit dots are at least d3 (for example, in the main scanning direction) in order to prevent adjacent add-online unit dots from approaching and conspicuous. (32 pixels).
[0140]
The data represented by the unit dot is determined by the phase difference between the unit dot 2202a and the unit dot 2201a. FIG. 22 shows an example representing 4-bit information. In the example shown in FIG. 22, the unit dot 2202a represents data "3". For example, if the unit dot 2202a is at the leftmost end, it represents data "0", and if the unit dot 2202a is at the rightmost end, it represents data "F".
[0141]
In FIG. 23, of the set of add-on lines representing all additional information, the line shown in FIG. 23A represents the first add-on line Line0, and the line shown in FIG. 23B represents the fourth add-on line Line3. As shown in FIG. 23, in Line 0, dots 2302a to 2302d are added at an interval of d4 (for example, 16 pixels) to the right of all of the original unit dots 2301a to 2301d, and in Line 3, the original unit dots are added. Dots 2305a to 2305d are added at intervals of d5 (for example, 32 pixels) to the right of all of 2304a to 2304d. These additional dots are markers for clarifying the order of each ad online. The reason why the markers are added to the two add-on lines is to enable the upper and lower portions in the sub-scanning direction to be determined even from the output image.
[0142]
Also, for example, if the pattern to be added is a full-color MFP such as the MFP 104, the color information of Y is used by utilizing the fact that the human eyes have a low discriminating ability with respect to a pattern drawn with Y toner. Only added by. As a result, additional information is not attached when the printout is performed.
[0143]
When this information is added as black information, it is added on as a visible image.
[0144]
In the case of a monochrome MFP like the MFP 105, a value of about -8 to +8 is added as add-on information to a signal value of a density signal of, for example, 256 gradations (8 bits) to a degree invisible to human eyes. To be added.
[0145]
Furthermore, the dot interval in the main scanning direction of the additional pattern and the repetition interval of all the additional information in the sub-scanning direction are surely set to a thin and uniform area where dots can be reliably identified in the target specific document. It must be determined that all information is added. As a guide, information may be added at a pitch equal to or less than half the width of a thin and uniform area where dots can be reliably identified in the specific original document.
[0146]
When both the user information and the paper discharge processing information are added, the information may be added alternately, or the information may be replaced every specific period. If the Y add-on information and the black density conversion information can be mixed, they can be added at the same position.
[0147]
The printout of such additional information is information that cannot be visually identified, but can be sufficiently identified when read by the apparatus of this embodiment. However, if the information having such information is further copied, this information is lost. Therefore, even if the copied paper is set in the finisher of this embodiment, the command is not valid. Further, by printing out the additional information on both sides, it is possible to cope with both of the image forming means of the back side discharge and the front side discharge.
[0148]
[Add-on Unit 212 in MFPs 104 and 105]
Next, a method for adding an add-on will be described. This corresponds to the add-on unit 212 in FIG. 2, and its circuit will be described with reference to, for example, FIG.
[0149]
First, a rasterized image signal 2401 is input from the PDL unit. At this time, add-on data is output in synchronization with the image signal 2401 from the add-on information page memory 2402 in which the add-on information described above with reference to FIGS. That is, the add-on information is stored in the add-on information memory 2402 as an add-on data in an information format as shown in FIG. 25, for example, an 8-bit data format in which data of -127 to +127 and the most significant bit is a sign bit. And the portion -4 correspond to the portions 1901-1903 in FIG.
[0150]
Referring back to FIG. 24, the image signal 2401 and the add-on data of the add-on information page memory 2402 which are read out synchronously are input to the adder 2403 or the subtractor 2404, and are saturated when they are higher than FFH or lower than 00H. As a countermeasure in the case of, the signal enters the selector 2407 through the OR gate 2405 or the AND gate 2406 and the carrier signal. The select signal 2408 of the selector is the most significant bit (sign bit) of the add-on information page memory, and is switched according to the sign of the add-on information as shown in FIG.
[0151]
Conversely, if the add-on data has already been added to the image signal 2401, the operation can be reversed by reversing the most significant bit (sign bit) of the add-on information page memory 2402 to cancel it. However, if the same add-on data is used, it is released.
[0152]
This add-on addition circuit is added to the YMC and K signal systems.
[0153]
By writing an additional pattern in each page memory 2402, each pattern can be added to an image.
[0154]
Here, if a pattern is written only in the Y page memory, it is added on only by Y.
[0155]
When the add-on is performed in black, if an additional pattern is written in the K page memory, the add-on is performed in black.
[0156]
Next, the operation of each apparatus when performing the printing and discharging processes will be described in detail with reference to the flowcharts of FIGS.
[0157]
Here, an operation of performing stapling processing on a sheet bundle copied from a document in which monochrome and color are mixed is described.
[0158]
In step S101, the operator first operates the terminal of the computer 103. An original in a mixture of color and black and white is created using well-known DTP software or the like.
[0159]
When printing is performed in step S101, the screen of the printer driver is displayed on the display of the computer 103 as shown in FIG. 15, and step S102 is executed. Details of step S102 will be described with reference to FIG.
[0160]
Here, designation of 1608 staples is performed.
[0161]
At 1602, a printer is designated. If the finishing function or the like is unknown, pressing a key 1607 to know the details displays detailed information (not shown).
[0162]
Since the original is a mixture of color and black and white, it is necessary to specify a black and white printer and a color printer.
[0163]
First, when the user selects the monochrome MFP 105 in the printer selection column 1602, the MFP 105 is set as the first printer in step S401.
[0164]
Next, by depressing the key 1609, a further printer selection column becomes valid, and the second printer, finisher, or the like can be selected. If it is determined in step S403 that the key 1609 is on and the selection of the second printer or the finisher is possible, step S405 is executed.
[0165]
When the name order is selected as the display priority method as shown in FIG. 26, step S406 is executed, and when the selection column of 1609 is right-clicked, selectable printers or finishers are displayed in order of name. If the distance to the first printer has been selected as the display priority method, step S407 is executed. In step S407, from the available printers or finishers, the distance between the printer or finisher other than the printer selected as the first printer and the printer selected as the first printer is calculated from the coordinate data, The print order in which the distance is short is determined, and in step S408, when the selection column 1609 is right-clicked, selectable printers or finishers are displayed in the print order close to the first printer.
[0166]
If the color MFP 104 is selected as the second printer in step S409, the MFP 104 is set as the second printer in step S410.
[0167]
If it is determined in step S403 that the key 1609 is off and selection of the second printer or finisher is prohibited, the setting of the second printer is cleared in step S404.
[0168]
When print start is instructed in step S402, that is, when the OK key 1605 is pressed, the process advances to step S103, and a JOB number display and a password input window are displayed as shown in FIG. Here, the JOB number is an arbitrary number generated by the computer 103 plus a character string logged by the operator, and serves as information for identifying the operator and the document. The password is necessary for the operation to be described later, and for example, a combination of alphabets and numbers of up to eight characters is input.
[0169]
When the OK key is pressed in step S103, the computer 103 creates print data (step S104). To the print data, commands such as staple processing, monochrome / color mixed processing, interlocking of two units, and add-on processing are added together with the conventional PDL drawing data.
[0170]
Note that the paper ejection process is performed by the MFP selected first in the column 1602. Alternatively, when a finisher is selected in the column 1609, the finisher gives priority to the paper discharge processing.
[0171]
When the data creation is completed, the data is transferred to the two designated MFPs.
[0172]
Step S105 is an operation of the MFP 105. The MFP 105 to which the data is transferred analyzes the processing command, draws only a black and white page, and temporarily stores the data in the memory. No add-ons will be done at that time.
[0173]
Step S106 is an operation of the MFP 104. The MFP 104 also analyzes the data and draws only a color page. This is a processing command in color, and a job number and the number of pages input by the printer driver are added on in yellow to start printing. . When the printing is completed, an end notification is sent to the computer 103. The print data is stored in the memory 108 of FIG.
[0174]
In step S107, since the color printing is completed on the computer 103, the computer 103 displays a message to set the discharged sheet on the finisher of the MFP 105 (not shown). This display is also displayed on the operation unit of the MFP.
[0175]
In step S108, the operator takes the paper from the paper discharge unit of the MFP 104 and sets the paper on the insert tray 1003a of the finisher of the MFP 105. The job number is input using the operation unit of the finisher or the operation unit of the MFP 105. Alternatively, a list of jobs is displayed, and a job is designated from the list. If a job number is directly input and there is no job with that number, a warning is displayed. If the processing is still in progress, a warning is displayed as such.
[0176]
When JOB is specified, a password is input. This is the password displayed in FIG. No one else can handle it. A warning is displayed even if the password is incorrect.
[0177]
When paper is set on the tray and a start key (not shown) of the finisher is pressed, the finisher reads the add-on information by a sensor while moving the paper to the tray 1003b. The job number is read from the add-on information, and the apparatus enters a password input standby state. If the order of the devices to be set is different, a warning is displayed on the operation unit.
[0178]
If the password is also correctly input, the process proceeds to step S109, where the MFP 105 reads the data for which the drawing processing has been completed from the memory and performs the paper discharge processing. At this time, the sheet is discharged in consideration of the order of the sheets on the tray 1003 of the finisher. For example, if the first page and the second page are output from the printer 105 and the third page is the first page of the MFP 104, the number of pages of the add-on information is 3, and when the MFP 105 discharges up to the second page, the finisher Paper corresponding to the third page is fed from the tray 1003b. This is the case of the back side discharge, and in the case of the front side discharge, the sheet is discharged from the last page.
[0179]
In step S110, when all the sheets are discharged and finishing processing such as stapling and punching is completed, a job completion notification is sent to the computer 103, the data in the memory 108 is erased, and the operation ends.
[0180]
Next, operations of the MFP 106 and the finisher 109 will be described in detail with reference to FIGS.
[0181]
Step S201: First, the operator operates the terminal of the computer 103. An original in a mixture of color and black and white is created using well-known DTP software or the like.
[0182]
Check the status of each device before printing.
[0183]
As shown in FIG. 17, the status of the apparatus is displayed on the utility software.
[0184]
In step S202, when the MFP 106 is displayed and a key for disconnecting the connection between the MFP and the finisher is pressed (not shown), the MFP 106 becomes an MFP without a finisher. Separation can also be set by the operation unit of the MFP 106 or the finisher 109.
[0185]
The utility software has a function called a device list to display a list of devices connected to the network. Before the main unit and the finisher were separated, three MFPs were seen as shown in FIG. 28. As a result, the finisher 109 starts the independent operation and supports the SNMP. Therefore, the three devices before the disconnection become visible as shown in FIG.
[0186]
In step S203, the operator checks the status of the device to which he / she wants to print, and when printing is performed, a screen of the printer driver is displayed on the display of the computer 103 as shown in FIG. 15, and step S204 is executed. Details of step S204 will be described with reference to FIG.
[0187]
First, when the monochrome MFP 106 is selected in the printer selection column 1602, in step S401, the MFP 106 is set as the first printer.
[0188]
Next, by depressing the key 1609, a further printer selection column becomes valid, and the second printer, finisher, or the like can be selected. If it is determined in step S403 that the key 1609 is on and the selection of the second printer or the finisher is possible, step S405 is executed.
[0189]
When the name order is selected as the display priority method as shown in FIG. 26, step S406 is executed, and when the selection column of 1609 is right-clicked, selectable printers or finishers are displayed in order of name. If the distance to the first printer has been selected as the display priority method, step S407 is executed. In step S407, from the available printers or finishers, the distance between the printer or finisher other than the printer selected as the first printer and the printer selected as the first printer is calculated from the coordinate data, The print order in which the distance is short is determined, and in step S408, when the selection column 1609 is right-clicked, selectable printers or finishers are displayed in the print order close to the first printer.
[0190]
If the color MFP 104 is selected as the second printer in step S409, the MFP 104 is set as the second printer in step S410.
[0191]
If it is determined in step S403 that the key 1609 is off and selection of the second printer or finisher is prohibited, the setting of the second printer is cleared in step S404.
[0192]
When print start is instructed in step S402, that is, when the OK key 1605 is pressed, the process proceeds to step S205, and a JOB number display and password input window are displayed as shown in FIG. Here, the JOB number is an arbitrary number generated by the computer 103 plus a character string logged by the operator, and serves as information for identifying the operator and the document. The password is necessary for the operation to be described later. For example, a combination of alphabets and numbers of up to eight characters is input.
[0193]
In step S206, when the OK key is pressed, the computer 103 creates print data. To the print data, commands such as staple processing, monochrome / color mixed processing, interlocking of two units, and add-on processing are added together with the conventional PDL drawing data. Note that the paper ejection process is performed by the MFP selected first in the column 1602. Alternatively, when a finisher is selected, the finisher is prioritized.
[0194]
When the data creation is completed, the data is transferred to the designated two MFPs and finisher 109. The transfer protocol is performed by the well-known LPR or the like.
[0195]
In step S207, the MFP 106 to which the data has been transferred analyzes the processing command, draws only a black and white page, and outputs it. When the processing is completed, the computer 103 is notified of the completion.
[0196]
The color MFP 104 also analyzes the data, draws only a color page, and starts printing. When the printing is completed, an end notification is sent to the computer 103.
[0197]
Each device has a job number, the number of pages, and the like added on.
[0198]
In step S208, the computer 103 finishes printing, and displays a message to set the discharged sheet on the finisher 109 (not shown). This display is also displayed on the operation unit of each device.
[0199]
In step S209, the operator takes out the paper from the paper discharge unit of the MFPs 104 and 106 and sets the paper on the insert trays 1003a and 1003c of the finisher 109. Enter the number of the operation unit JOB of the finisher. Alternatively, a list of jobs is displayed, and a job is designated from the list. If a job number is directly input and there is no job with that number, a warning is displayed. If the processing is still in progress, a warning is displayed as such.
[0200]
When JOB is specified, a password is input. This is the password displayed in FIG. No one else can handle it. A warning is displayed even if the password is incorrect.
[0201]
When sheets are set on the tray and the start key (not shown) of the finisher is pressed, the finisher reads the add-on information by the sensor while moving the sheets to the trays 1003b and 1003d. The job number is read from the add-on information, and the apparatus enters a password input standby state. If the order of the devices to be set is different, a warning is displayed on the operation unit.
[0202]
Also, when handling paper without add-on information of the finisher, it is possible to set the processing of the paper on each insert tray with the operation unit of the finisher.
[0203]
If the password is also correctly input in step S210, the sheets on the trays b and d are fed in the specified order and the finishing process is performed.
[0204]
In step S211, when all the sheets have been discharged and all finishing processes such as stapling and punching have been completed, the computer 103 is notified of the end of the job.
[0205]
When the finisher 109 is reconnected to the main body, the finisher 109 becomes an MFP integrated with the main body, disappears from the device list as shown in FIG. 28, and all operations end.
[0206]
Next, the operation of each device when the server 102 handles JOB will be described in detail with reference to FIGS.
[0207]
First, in step S301, the operator operates the terminal of the computer 103. An original in a mixture of color and black and white is created using well-known DTP software or the like.
[0208]
The operator checks the status of the device to which he / she wants to print, and when printing is performed, a screen of the printer driver is displayed on the display of the computer 103 as shown in FIG. 15, and step S302 is executed. Details of step S302 will be described with reference to FIG.
[0209]
First, when the user selects the monochrome MFP 105 in the printer selection column 1602, the MFP 105 is set as the first printer in step S401.
[0210]
Next, by depressing the key 1609, a further printer selection column becomes valid, and the second printer, finisher, or the like can be selected. If it is determined in step S403 that the key 1609 is on and the selection of the second printer or the finisher is possible, step S405 is executed.
[0211]
When the name order is selected as the display priority method as shown in FIG. 26, step S406 is executed, and when the selection column of 1609 is right-clicked, selectable printers or finishers are displayed in order of name. If the distance to the first printer has been selected as the display priority method, step S407 is executed. In step S407, from the available printers or finishers, the distance between the printer or finisher other than the printer selected as the first printer and the printer selected as the first printer is calculated from the coordinate data, The print order in which the distance is short is determined, and in step S408, when the selection column 1609 is right-clicked, selectable printers or finishers are displayed in the print order close to the first printer.
[0212]
If the color MFP 104 is selected as the second printer in step S409, the MFP 104 is set as the second printer in step S410.
[0213]
Further, when the finisher 109 is selected by the selection column 1609, in step S410, the MFP 104 and the finisher 109 are also set as the second printer as the second printer.
[0214]
The finisher 109 is selected by the selection column 1609, and staple designation is performed in 1608.
[0215]
Even if the finisher is specified in the MFP 104 or the like because the finisher is designated, the setting for the finisher 109 is prioritized. Alternatively, if there is a process that is not in the finisher 109 and can be performed by the finisher of the MFP 104, the setting is also effective.
[0216]
If it is determined in step S403 that the key 1609 is off and selection of the second printer or finisher is prohibited, the setting of the second printer is cleared in step S404.
[0219]
When print start is instructed in step S402, that is, when the OK key 1605 is pressed, the process proceeds to step S303, and a JOB number display and a password input window are displayed as shown in FIG. Here, the JOB number is an arbitrary number generated by the computer 103 plus a character string logged by the operator, and serves as information for identifying the operator and the document. The password is necessary for the operation to be described later. For example, a combination of alphabets and numbers of up to eight characters is input.
[0218]
In step S303, when the OK key 1605 is pressed, a job number display and password input window are displayed as shown in FIG. Here, the JOB number is an arbitrary number generated by the computer 103 plus a character string logged by the operator, and serves as information for identifying the operator and the document. The password is necessary for the operation to be described later. For example, a combination of alphabets and numbers of up to eight characters is input.
[0219]
In step S304, when the OK key is pressed, the computer 103 creates print data. To the print data, commands such as staple processing, monochrome / color mixed processing, interlocking of two units, and add-on processing are added together with the conventional PDL drawing data. Note that the paper ejection process is performed by the MFP selected first in the column 1602. Alternatively, when a finisher is selected in the column 1609, the finisher gives priority to the paper discharge processing. When the data has been created, the print data is transferred to the computer 102.
[0220]
In step S305, the computer 102 to which the data has been transferred analyzes the processing command, reconstructs data of only a black and white page, and issues a print command to the MFP 105. Also, it reconstructs only the data of the color page and issues a print command to the MFP 104.
[0221]
In step S306, each MFP receives and prints the data based on the data, and when completed, notifies the computer 102 of the operation end.
[0222]
In step S307, the computer 102 notifies the computer 103 of an end notification.
[0223]
Since the printing is completed, the computer 103 displays a message to set the discharged sheet on the finisher 109 (not shown).
[0224]
The operator takes the paper from the paper ejection unit of the MFP 104 or 105 and sets the paper on the insert tray 1003 a or 100 c of the finisher 109.
[0225]
In step S308, when the user logs in to the computer 102 using the operation unit of the finisher and selects and executes his / her own job from the list of jobs, the computer 102 issues an operation instruction to the finisher 109. This instruction includes the order of sheets stacked on the trays 1003a and 1003c and a processing instruction. In step S309, the finisher 109 feeds the sheets in the trays 1003b and 1003d in the designated order and performs a finishing process.
[0226]
In step S310, when all sheets are ejected and finishing processing such as stapling and punching is completed, the computer 102 notifies the computer 102 of the end of the job. Write and notifies the computer 103 of the end of JOB.
[0227]
The computer 103 displays the end and ends the operation.
[0228]
