BACKGROUND OF THE INVENTION
The present invention relates to a printing system in which a user-side data processing device, a center-side data processing device, and a printer are connected by a communication line or the like, and an image file designated from the user-side data processing device is transmitted to the printer via a communication line. About.
[0002]
[Prior art]
In recent years, with the spread of personal computer communications and the increase in image software, personal computer users can easily display all kinds of images on a home display screen. In addition, it is easy to print these images on paper by improving the performance and reducing the price of the printer.
[0003]
However, a high-performance printer that can obtain a color image with an image quality close to that of a silver halide photograph and can print on a large-size sheet is still expensive for a general user to own.
[0004]
Therefore, a user's personal computer and a high-performance color printer are connected by a communication line so that each user can use this color printer in common, and each user does not have a dedicated high-performance color printer. A printing system that can obtain a high-quality print has been proposed.
[0005]
FIG. 19 is a block diagram showing an outline of a conventional printing system 800.
19, a print system 800 includes personal computers 802a to 802c used by a user, a high-performance color printer 804, a printer control device 805 for controlling the color printer 804, a display 803 attached to the printer control device 805, and communication. It consists of a line 806. Each of the personal computers 802a to 802c is installed in the user's home, and the color printer 804 and the printer control device 805 are installed in, for example, a convenience store.
[0006]
When the user desires to print, for example, the image file DFA is input to the personal computer 802a, and at the same time, a print reservation command and a user name are input.
[0007]
Then, the personal computer 802a assigns an image file number 903a to the input image file DFa and transmits it to the printer control device 805 and the color printer 804 as a header file 902a together with the user name. Therefore, the header files 902a to 902c transmitted from each user are stored in the printer control device 805 and the color printer 804. At this time, the image file DFA is not yet transmitted.
[0008]
Next, the user goes to a convenience store and instructs the printer control device 805 and the color printer 804 to execute printing.
That is, on the screen of the display 803 of the printer control device 805, a large number of image file numbers 903a to 903c and user names transmitted from each user are displayed.
[0009]
The user finds his / her user name and image file number 903a from the screen, and inputs a print execution command to the found image file number 903a. Then, the corresponding image file DFa is transmitted from the personal computer 802a to the color printer 804, stored in the printer memory 807, and then printed (Japanese Patent Laid-Open No. 9-39311).
[0010]
[Problems to be solved by the invention]
However, in the conventional system, the image file DFa is transmitted to the color printer 804 after the user operates the color printer 804 to execute printing of the image file DFa. There is a waiting time in between.
[0011]
In general, the higher the image quality and the larger the size, the larger the capacity of the image file, and the longer it takes to transmit the image file. Therefore, useless waiting time for the user tends to increase. In addition, since printing is not executed during that time, the operating time of the color printer 804 is also reduced.
[0012]
On the other hand, it is conceivable that all the image files DFa transmitted from the personal computer 802a are transmitted to the color printer 804 in advance, but in this case, the color printer 804 is provided with a large number of image files DFa. A large-capacity memory for storage is required, which increases the cost.
[0013]
The present invention has been made in view of the above-described problems, and does not require a large-capacity memory in the printer, and can eliminate a waiting time for transmitting a data file when executing printing in the printer. The purpose is to provide a system.

Next, the image print information PD will be described.
FIG. 8 is a diagram showing an example of the configuration of the image print information PD1 stored in the storage device 41 of the center side data processing device 4, and FIG. 9 is a diagram for explaining the relationship between the data code DC and the ID code UC. .
[0066]
As shown in FIG. 8, as the image print information PD1, the data code DC, the reception date / time JT, the transmission date / time ST, the reservation date / time RD, the fee form FM, the image file DF, the reservation presence / absence RI, the erasure remaining time ET, and the ID code UC It is included.
[0067]
The data code DC is for each user to identify each image file DF. As the data code DC, the user usually assigns a unique code that is easy for the user to remember to each image file DF managed by the user. Therefore, regarding the image file DF managed by the user himself / herself, the data code DC differs depending on the image file DF, but the same data code is used regardless of the difference in the image file DF in relation to the data code DC of other users. DC may be applied. As the data code DC, alphanumeric characters are generally used, but kanji, hiragana and katakana can also be used. In the present embodiment, only numbers are used so that input from the numeric keypad 181 is possible. The data code DC may be the same as the file name of the image file DF. Therefore, a file name can be used instead of the data code DC. The data code may be referred to as “user code”.
[0068]
The data code DC is data that may be known to other users. When the list of data codes DC is displayed in the copying machine 3, each user can easily select his / her data code DC to be printed from the displayed list. In this case, in order to actually perform printing, it is necessary to input an ID code UC described below along with the data code DC.
[0069]
The ID code UC is a code assigned for each user and should not be known to other users. In this embodiment, every time the image print information PD is transmitted to the center-side data processing device 4, it is regarded as one user, and one ID code is assigned to one transmitted image print information PD. UC is assigned. Note that one image file DF can be regarded as one user.
[0070]
That is, when the image print information PD is transmitted from the user side data processing device 5 to the center side data processing device 4, one ID code UC is assigned to one image print information PD in the center side data processing device 4. Generated automatically. The generated ID code UC is stored as a part of the image print information PD in the center side data processing device 4 and is returned to the user side data processing device 5.
[0071]
One image print information PD includes one or a plurality of data codes DC, that is, one or a plurality of image files DF to be printed, but includes a plurality of data codes DC (image files DF). Even in this case, one ID code UC corresponds to one image print information PD.
[0072]
The user inputs the ID code UC obtained for the image print information PD specified by the user in the copying machine 3, thereby causing the copying machine 3 to print the image file DF specified by the image print information PD. It can be done. That is, the ID code UC has a function for maintaining security so that an image file DF designated by the user is not printed by another person.
[0073]
As the ID code UC, alphanumeric characters, kanji, hiragana, katakana, and the like can be used, but in this embodiment, only numbers are used so that input from the numeric keypad 181 is possible.
[0074]
As shown in FIG. 9, when three image files DF “A”, “B”, and “C” are designated by one image print information PD, one ID code UC “1234” is generated correspondingly. The generated ID code UC is assigned to the user. In this case, the same ID code UC “1234” corresponds to any of the data codes DC “111”, “222”, and “333”.
[0075]
The user needs to remember the data code DC input by the user and the ID code UC corresponding thereto. For this purpose, those displayed on the screen of the display 51 may be noted, but in the present embodiment, they can be recorded in the storage media MM1 and MM2. Moreover, the recorded storage media MM1, 2 can be set in the storage media reader 39 of the copying machine 3, and the data code DC and the ID code UC can be directly input from the storage media MM1, 2 to the copying machine 3.
[0076]
Therefore, the trouble of memorizing and taking note of the data code DC and the ID code UC can be saved, and the trouble of manipulating the operation panel 18 for inputting in the copying machine 3 can be saved. The data code DC and the ID code UC can always be input accurately.
[0077]
Returning to FIG. 8, the reception date and time JT is the date and time when the center side data processing device 4 received the image print information PD, and the year, month and date and time are automatically recorded by the internal clock of the center side data processing device 4. . The transmission date and time ST is the date and time (year / month / day / minute) when the image file DF was transmitted to the copying machine 3. The reservation date / time RD is the date / time (year / month / day / hour) when the user designates the date / time for printing. However, if only the date is specified as the reservation date and time RD and the hour and minute are not specified, it is considered that the night print is instructed.
[0078]
The fee form FM designates a payment form of the print fee, and records “prepaid payment”, “postpay”, “transferred”, and the like. “Prepayment” or “transferred” indicates that when the image print information PD is transmitted from the user side data processing device 5 to the center side data processing device 4, the cost required for the printing has been paid in advance. As such a fee payment method, various payment methods by data communication called electronic money, electronic banking, electronic approval, etc., or a payment method by debiting from a bank account opened in advance can be adopted. In the case of “prepayment”, for example, when the image print information PD is transmitted to the center-side data processing apparatus 4 and the ID code UC is assigned thereto, the charge for the print is deducted from the advance payment amount. When the image file DF is designated and sent for printing, for example, “transferred” is set.
[0079]
By making the advance payment or the transfer in this way, there is an advantage for the user that the holding time of the image print information PD in the center side data processing device 4 is extended. Therefore, when the execution of printing in the copying machine 3 may be delayed, the user pays the fee in advance as prepaid or transferred in order to avoid the trouble of transmitting the image print information PD again. desirable. “Post-payment” indicates that, for example, when the printing is actually executed in the copying machine 3, coins are inserted into the coin insertion slot 222 and paid.
[0080]
The image file DF is image data as the contents of the image file DF. However, since image data generally has an extremely large amount of data compared to other data, only the file name may be recorded here, and the actual data may be held separately. When the image file DF is erased, “erased” is recorded. The reservation presence / absence RI is recorded in accordance with the recording of the reservation date / time RD, such as “present” and “not present”. The remaining deletion time ET indicates the remaining time (hours and minutes) until each image print information PD stored in the storage device 41 is deleted.
[0081]
FIG. 10 is a sequence diagram showing processing and operation of the printing system 1.
In FIG. 10, first, the user operates the user side data processing device 5 and transmits the image print information PD including the image file DF desired to be printed to the center side data processing device 4 (S1). As a result, a print request is made to the center side data processing device 4. At this time, it is also possible to remit the print fee electronically to the center-side data processing device 4 or to settle it.
[0082]
When the center side data processing device 4 receives the image print information PD, a different ID code UC is generated for each user, that is, for each image print information PD, and the generated ID code UC is assigned to the corresponding user side. The data is transmitted to the data processing device 5 (S2). In the user-side data processing device 5, the received ID code UC is displayed on the screen of the display 51. The user records the received ID code UC in the storage media MM1 and MM2. When the storage media MM1, 2 are not present, the user remembers the ID code UC displayed on the screen.
[0083]
The center-side data processing device 4 transmits the ID code UC and transmits information (image holding information) indicating that the image file DF is held to the target copying machine 3 together with the data code DC. To do. At that time, information on the reservation date and time RD and the fee form FM is also transmitted (S3). The transmitted image holding information is stored in the memory 131 of the copying machine 3. The image holding information does not include the image file DF.
[0084]
At the same time, time counting (timing) for obtaining the timing for erasing the set of received image print information PD is started (S4). When this time count ends, the image file DF corresponding to the ID code UC is deleted, and information indicating that the data code DC and the image file DF have been discarded is transmitted to the target copying machine 3 (S13).
[0085]
If the image print information PD includes the reservation date and time RD, and 10 minutes before the time designated by the reservation date and time RD (S16), the center side data processing device 4 includes the image print information PD in the image print information PD. The corresponding image file DF, information indicating whether or not the charge transfer has been completed, and the ID code UC are transmitted to the copying machine 3 (S17). In the copying machine 3, the transmitted information is stored in the memory 131. This eliminates the need for waiting for the image file DF to be transmitted from the center-side data processing device 4 when the user operates the copying machine 3 to instruct execution of printing, thereby eliminating unnecessary waiting time.
[0086]
Now, after transmitting the image print information PD from the user-side data processing device 5, the user has designated the storage medium MM1, 2 on which the received ID code UC is recorded, preferably at the time designated by the reservation date and time RD. Visit a convenience store with a designated copy machine 3, for example.
[0087]
In the copying machine 3, the user operates the operation panel 18, sets the storage media MM1 and 2 in the storage media reader 39, and inputs the data code DC and ID code UC which are user codes (S5). If there are no storage media MM 1 and 2, they are input from the operation panel 18.
[0088]
When the user code is input, the copying machine 3 checks or checks whether the input data code DC exists in the data code DC stored in the memory 131. If the ID code UC has already been transmitted from the center-side data processing device 4 in the case where it exists, whether the input ID code UC exists in the ID code UC stored in the memory 131. Check or check for no.
[0089]
If the user operates the copying machine 3 earlier than the time designated by the reservation date and time RD, the ID code UC or the like has not been transmitted to the copying machine 3 yet. Information requesting the image file DF (image request) is transmitted to the center side data processing device 4 together with the ID code UC (S6).
[0090]
When the center-side data processing device 4 receives the image request, the center-side data processing device 4 collates the received ID code UC with the ID code UC stored in the storage device 41 and checks whether or not they match (S8). If the ID code UC and the corresponding data code DC match, the corresponding image file DF, information on whether or not the charge transfer has been completed, and the data code DC are transmitted to the copying machine 3. (S7).
[0091]
That is, if the ID code UC transmitted to the user-side data processing device 5 and the ID code UC input by the user in the copying machine 3 match, printing is possible, but if they do not match, printing is performed. I can't. This prevents erroneous printing of the image file DF and unauthorized printing of the image file DF by others.
[0092]
When the user presses the start key 186 on the operation panel 18, the copying machine 3 starts printing the designated image file DF (S9). The user needs to pay the fee by transferring the fee to a predetermined account in advance or by inserting a coin into the coin insertion slot 222 of the vendor apparatus 200.
[0093]
When printing is normally completed in the copying machine 3 (S11), the copying machine 3 transmits data erasure instruction information together with the data code DC to the center side data processing device 4 (arrow S12). When the center side data processing device 4 receives the data erasure instruction information, the image print information PD corresponding to the data code DC is erased from the storage device 41. Thereby, the utilization factor of the storage device 41 is improved.
[0094]
If printing is interrupted due to paper shortage or the like during printing by the copying machine 3, data holding instruction information is transmitted from the copying machine 3 to the center side data processing device 4 (S10). When the center-side data processing device 4 receives the data holding instruction information, the time count for erasing the corresponding image print information PD is temporarily stopped or the count time is extended.
[0095]
Even when the image file DF is not printed in the copying machine 3, the image print information PD stored in the storage device 41 of the center-side data processing device 4 is compulsory when the time count ends. Will be erased.
[0096]
By the way, since there are few users of the copying machine 3 at night and the electricity charge is low, there are cases where printing is performed aiming at night. If night is designated as the reservation date and time RD, or if no time is designated, an automatic print instruction is given when the night is entered (S14).
[0097]
When the automatic print instruction is given, the center side data processing device 4 transmits the automatic print instruction information together with the data code DC and the image file DF to the copying machine 3 (S15). When receiving the automatic print instruction information, the copying machine 3 executes printing of the image file DF. At that time, information such as the data code DC may be automatically added to the printed image. In this case, the printed paper is handed over to the user in exchange for a fee at a later date. If the fee has already been transferred, the user can obtain the data code DC and the ID code UC by presenting them.
[0098]
Next, the processing operation of each part of the print system 1 will be described based on a flowchart.
11 is a flowchart showing the overall processing in the center side data processing apparatus 4, FIG. 12 is a flowchart showing the contents of the receiving process, FIG. 13 is a flowchart showing the contents of the data erasing process, and FIG. 14 shows the contents of automatic printing. It is a flowchart.
[0099]
These processes are performed by executing the program BP stored in the storage device 41 of the center-side data processing device 4.
In FIG. 11, the center side data processing device 4 receives data from the user side data processing device 5 and the copying machine 3 (# 200), and stores the data stored in the storage device 41 of the center side data processing device 4. A data erasure process (# 300) to be erased and an automatic print instruction process (# 400) for the case where there is a reservation and night print are performed.
[0100]
In FIG. 12, in the reception process, when the image print information PD is received from the user side data processing device 5 (Yes in # 202), the received image print information PD is stored together with the reception date and time JT, and the ID code UC is generated. The data is transmitted to the user side data processing device 5 (# 204). Then, image holding information indicating that the image file DF is held is transmitted to the copying machine 3 together with the data code DC (# 206). Accordingly, the received data code DC is recorded in the memory 131 in the copying machine 3. At the same time, a timer TM (N) for obtaining a timing for erasing the stored image print information PD is set for each user, and time counting is started (# 208).
[0101]
When there is a request for the image file DF from the copying machine 3 (Yes in # 210), it is checked whether or not the same ID code UC as the ID code UC related to the request is stored in the storage device 41 (# 212). If there is a match, the corresponding image file DF and fee transfer information are transmitted to the copying machine 3 together with the data code DC (# 214).
[0102]
In FIG. 13, when the time count by the timer TM (N) for each user has ended (Yes in # 302), it is determined whether or not the print fee of the user whose time count has ended is paid (# 304) If the payment has not been made, data destruction information about the user is transmitted to the copying machine 3 to prompt the destruction of the stored data code DC (# 306). Then, the image print information PD stored in the storage device 41 of the center side data processing device 4 is deleted (# 308).
[0103]
If the user's print fee has been paid in step # 304, the data discard information is not transmitted to the copying machine 3, and the image print information PD stored in the storage device 41 is not erased. That is, when the print fee is paid, the user can always execute printing by the copying machine 3, or can set the reservation date and time RD late. This improves convenience for the user who pays the print fee.
[0104]
If the image print information PD is not erased indefinitely when paying a print fee, it may be inconvenient, so it may be erased after a certain period of time or the user side It is conceivable to send a warning message to the data processing device 5 or to output a report to that effect from the center side data processing device 4 to notify the user from the administrator.
[0105]
If the timer TM (N) has not finished counting in step # 302, it is determined whether or not a data erasure instruction has been received from the copying machine 3. If a data deletion instruction has been received, the corresponding data is deleted in step # 308.
[0106]
In FIG. 14, it is searched whether there is a reserved one among the users who store the image print information PD (# 402). If there is a reservation, it is determined whether or not the reservation date and time RD is specified (# 404).
[0107]
If the reservation time is specified and the current time is 10 minutes before the specified time (Yes in # 406), the corresponding image print information PD and ID code UC are transmitted to the copying machine 3. (# 410). In this way, the image file DF is transmitted to the copying machine 3 when the time specified by the reservation date and time RD has reached 10 minutes before, so that the user can print in the copying machine 3 for printing. When this instruction is issued, there is no need to wait for transmission of the image file DF, and printing can be performed as quickly as possible, which is efficient.
[0108]
If there is no designation of time even if there is a reservation, it is determined whether or not the present is night (# 408). In determining whether it is nighttime, the current time is, for example, between 10 pm and 3 am. If the answer is yes in step # 408, that is, if the current time is night, the image file DF is transmitted to the copying machine 3 together with the automatic print instruction information in step # 410 (# 410).
[0109]
15 is a flowchart showing the overall processing in the copying machine 3, FIG. 16 is a flowchart showing the content of the image request processing, FIG. 17 is a flowchart showing the content of the data erasing processing, and FIG. 18 is a flowchart showing the content of the printing processing. is there.
[0110]
These processes are performed by executing the program CP stored in the memory 131 of the copying machine 3.
In FIG. 15, when the copying machine 3 is energized, first, an initial setting for setting a timer that defines the time for one routine of this routine is performed (# 500). Then, an image request process for requesting the image file DF from the center side data processing apparatus 4 (# 600), a data erasure process for discarding the received image file DF, etc. (# 700), an image file from the center side data processing apparatus 4 Print processing (# 800) for receiving the DF and printing of the received image file DF and other processing (# 900) are sequentially performed, and when a predetermined time is counted (Yes in # 999), the process returns to step # 600.
[0111]
In FIG. 16, it is determined whether or not the code input key 188 on the operation panel 18 has been pressed (# 602), and the display unit 187 is turned on and off each time the code input key 188 is pressed (# 604). 606, 608). When the display unit 187 is lit, the user code, that is, the data code DC and the ID code UC are entered.
[0112]
When there is an input from the numeric keypad 181 (Yes in # 610), if the display unit 187 is lit (Yes in # 612), the input numeric string is stored in the memory 131 as the data code DC (#). 614). The input data code DC is checked, and if there is a matching data code DC (Yes in # 616), the display unit 187 is made to blink (# 618).
[0113]
If there is an input from the numeric keypad 181 while the display unit 187 is blinking (Yes in # 610, No in # 612, Yes in # 620), the input numeric string is stored in the memory 131 as the ID code UC ( # 622). Then, an image request is transmitted to the center side data processing device 4 (# 624), and then the display unit 187 is turned off (# 626).
[0114]
When it is detected that the storage media MM1, 2 are set in the storage media reader 39 (# 628), the data code DC and the ID code UC are loaded from the storage media MM1, 2 (# 630). The loaded data code DC is checked, and if there is a matching data code DC (Yes in # 632), an image request is transmitted to the center side data processing device 4 (# 634).
[0115]
In FIG. 17, it is determined whether data discard information has been received from the center side data processing device 4 (# 702). When the data discard information is received, the user does not execute the printing within a predetermined time or period (for example, several days) even though he / she wishes to print it. The data code DC stored in the memory 131 of the copying machine 3 is deleted (# 710). Thereafter, when the image file DF corresponding to the data code DC is held in the memory 131, the image file DF is also deleted (# 714).
[0116]
If the data discard information has not been received in step # 702, it is determined whether or not all printing in the copying machine 3 has been completed (# 704). If all printing has been completed, the data code DC is deleted in step # 710. If printing has not been completed, it is determined whether or not all inserted coins have been returned (# 706). If all coins have been returned, the process is interrupted before all printing is completed. Therefore, the center side data processing device 4 is instructed to hold the data so as not to delete the image print information PD immediately (# 712).
[0117]
If there is no coin return operation in step # 706, it is determined whether or not the time measured by the timer TM1 has elapsed since the data code DC was received from the center side data processing device 4 (# 708). If the time has elapsed, it is considered that printing has been left uninterrupted, and a data holding instruction is transmitted in step # 712.
[0118]
In FIG. 18, first, it is determined whether or not the image holding information and the data code DC are received from the center side data processing device 4 (# 802). If received, the timer TM1 for measuring time for erasing the image data is set for each user, and the time measurement is started (# 804). The received data code DC is stored in the memory 131 (# 806). The data code DC stored in the memory 131 is compared with the data code DC input by the user later in the copying machine 3.
[0119]
If the received data includes information on the reservation date and time RD (Yes in # 808), the received image file DF is stored in the memory 131 (# 810).
[0120]
Next, it is determined whether or not the user has come to the copying machine 3 and pressed the start key 186 of the operation panel 18 (# 812). When the start key 186 is pressed, the fee has already been transferred (Yes in # 816) or the necessary coin has been inserted into the coin slot 222 (Yes in # 818), and other print conditions are If everything is ready (Yes in # 820), the corresponding timer TM1 is reset (# 822), and execution of printing is started (# 824).
[0121]
If the start key 186 has not been pressed in step # 812, it is determined whether or not an automatic print instruction has been received from the center side data processing apparatus 4 (# 814), and if an automatic print instruction has been received, Step # 816 and subsequent steps are executed.
[0122]
It should be noted that the image file DF is transmitted in advance in step # 410 of the center side data processing device 4, but in this case, since an automatic print instruction is not performed, it is determined in step # 814 that there is no automatic print instruction. The
[0123]
The image print information PD excluding the image file DF described above is the print information of the present invention, the function of the processing unit 59 and the process of S1 are the print information transmitting means of the present invention, the process of step # 206 and the process of S3 are the present invention. Step # 214 and Step S7 are the data file transfer means of the present invention, Steps # 406 and 410 and Steps S16 and S17 are the spontaneous transfer means of the present invention and the start key. Reference numeral 186 corresponds to the input means of the present invention, and the processes of steps # 812, 814, and 824 and the process of S9 correspond to the print start means of the present invention.
[0124]
According to the printing system 1 of the above-described embodiment, when the user transmits the image print information PD from the user-side data processing device 5 to the center-side data processing device 4 and sends a print request, the request is responded. The ID code UC is given from the center side data processing device 4, and when the printing is actually performed in the copying machine 3, the ID code UC is checked together with the data code DC included in the image print information PD. Therefore, the user can definitely print the image file DF requested to be printed by the ID code UC, and can prevent others from printing the image file DF by mistake.
[0125]
In addition, the user who requested the printing records the data code DC and the ID code UC in the storage media MM1 and 2, and has the storage media MM1 and 2 directly to the copying machine 3 with the data code DC and the ID code UC. Therefore, the data code DC and the ID code UC can be input easily and accurately.
[0126]
The image file DF transmitted from the user side data processing device 5 to the center side data processing device 4 by the user is actually printed by the copying machine 3 or until a predetermined time before the reservation date and time RD, the center side data processing device 4. And is not transmitted to the copying machine 3, so that even when a large number of users request printing, the storage capacity required for the copying machine 3 does not increase so much. The increase can be suppressed.
[0127]
In the above-described embodiment, when the image print information PD is transmitted from the user side data processing device 5 to the center side data processing device 4, the image file DF is also included as the image print information PD. Without including the image file DF in the information PD, after the image request is received from the copying machine 3, or when the predetermined time before the reservation date and time RD, the user side data processing device 5 to the center side data processing device 4 Alternatively, the image file DF may be transmitted directly to the copying machine 3. In this way, the storage capacity in the center side data processing device 4 can be reduced.
[0128]
In the above-described embodiment, the center-side data processing device 4 and the copying machine 3 can be connected by a common network including the user-side data processing device 5, and the center-side data processing device 4 can be copied. It is also possible to connect the machine 3 by a dedicated line different from the network connecting the center side data processing device 4 and the user side data processing device 5. In addition, one center side data processing device 4 is provided for one copying machine 3 and these are connected. When the user requests printing from the user side data processing device 5, printing is performed from the beginning. The image print information PD may be transmitted to the center side data processing device 4 of the copying machine 3 to be performed. The print system 1 may be realized as a client server system.
[0129]
In the above-described embodiment, the ID code UC input by the user from the copying machine 3 is collated with the ID code UC that is once transmitted to the center-side data processing device 4 and stored in the storage device 41 of the center-side data processing device 4. However, the ID code UC stored in the storage device 41 of the center-side data processing device 4 may be transmitted to the copying machine 3 and collation thereof may be performed in the copying machine 3.
[0130]
In the above-described embodiment, the digital copying machine 3 is used to print the image file DF. However, a single printer device may be used. In other words, for example, a high-performance printer device can be connected to the center-side data processing device 4 and used. In addition, various printer devices capable of printing the image file DF, such as a device with a facsimile function added, can be used.
[0131]
In the above-described embodiment, the structure, circuit, function, operation method, processing content or order of the user-side data processing device 5, the center-side data processing device 4, and the copying machine 3, the content or order of each flowchart, and the sharing of processing These can be appropriately changed in accordance with the gist of the present invention.
[0132]
【The invention's effect】
According to the present invention, the printer does not require a large-capacity memory, and the waiting time for data file transmission when printing is performed in the printer can be eliminated.
[0133]
According to the invention of claim 3, the data file is always transmitted to the printer at the printing time scheduled by the user, and the transmission time of the data file can be adjusted according to the printing time scheduled by the user. Therefore, it is possible to minimize the data file stored in the memory of the printer.
