And erasing the print data temporarily stored in the data storage means from the image memory 207 when the time corresponding to the time data elapses, and implementing the processing operation such as the central control unit 201 as a control program. Have been.

In the above-described configuration, in the data processing system 1 of the present embodiment, for example, a plurality of data processing terminals 2 can share one printer device 3 and a plurality of data processing terminals 2 One print device 3 prints out print data to be transmitted to the printer.

However, the print data is not printed out when the data is transmitted, and the print ID is returned as password data from the printer device 3 to the data processing terminal 2 in response to the data transmission of the print data. When an ID is directly input to the printer device 3, data printing is started. The data processing method of the data processing terminal 2 and the printer device 3 of the data processing system 1 will be sequentially described below.

First, in the data processing terminal 2, as shown in FIG. 8, the user generates print data by operating the keyboard 110 as desired (step S1). An address or the like is added to the header information of the print data as identification data (step S2). At this time, the guidance for inputting the storage time of the print data is displayed and output on the display 112. When the user who confirms this inputs the storage time with the keyboard 110 or the like (step S3), this is the time data. Is added to the header information of the print data (step S4). The print data in which the identification data and the time data are added to the header information as described above is transmitted to the communication I / F.
The data is transmitted to the printer device 3 by the controller 113 (step S5), and when the data transmission is completed, the data processing terminal 2 waits for reception of the print ID data (step S5).
6).

In the printer device 3, as shown in FIG.
The printer is always on standby for receiving the print data and inputting the print ID (steps T1 and T2). When the print data is received, the print ID which is the password data is printed in accordance with the identification data of the header information. Assigned to the data (step T3). Next, time data of the storage expiration date is generated corresponding to the time data of the header information (step T).
4) At the same time, print data is stored in the image memory 207 (step T5), and a data pointer and time data are stored in the correspondence table 206 for each print ID.
(Step T6). Next, the print ID assigned to the print data as described above is transmitted to the data processing terminal 2 by the data transmission unit 203 in accordance with the identification data.

Therefore, in this data processing terminal 2, FIG.
As shown in (1), when the print ID is received (step S6), the print ID is notified to the user by display on the display 112 (step S6).
7). That is, when the user generates print data at the data processing terminal 2 and transmits the data, a print ID for the print output is notified and output. Therefore, when the user actually requests the print output, the print ID is printed. The ID is stored and moved to the position of the printer device 3, and the print ID is input to the input operation unit 204.

Therefore, in the printer device 3, as shown in FIG.
(Step T2), the print ID
From the correspondence table 206 (step T3). At this time, if the print ID is not retrieved from the correspondence table 206 (step T9), an error message is displayed on the data display unit 205 and the processing operation is terminated (step T10).

When the print ID is searched from the correspondence table 206, all the data pointers stored together with the print ID are detected, and the print data is read from the image memory 207 by the data pointer. When the print data is read in this way, it is determined whether or not the layout mode has been set (step T11).
When the layout mode has not been set, FIG.
As shown in FIG. 6A, the print data is sequentially printed out without being laid out (step T13). When the layout mode is set, a plurality of print data are output as shown in FIG. Are printed out after being laid out (steps T12 and T13).

In the printer device 3, as shown in FIG. 10, the central control unit 201
06 is constantly compared with all the time data stored in the table (step E1). If the time data matches the current time, the print ID and the data pointer stored in the correspondence table 206 together with the time data are deleted. ,
The print data stored in the image memory 207 is deleted at the position of the data pointer (step E2).

In the data processing system 1 of the present invention, as described above, even if the user sends print data to the printer device 3 through the data processing terminal 2, print output is not started, and Print on 2
D is transmitted and the user is notified and output. Then, when the user who confirms the print ID moves to the position of the printer device 3 and inputs the print ID to the printer device 3, the print output is started.

For this reason, the user executes only the necessary data printing, thereby preventing unnecessary data printing from being performed carelessly. Further, since the printed hard copy is immediately obtained by the user, it is not necessary to sort the hard copies by a plurality of users, and the occurrence of jams due to accumulation of hard copies is prevented.

Moreover, since the print ID is assigned to each user in accordance with the identification data, the printer 3 can print out a plurality of print data transmitted from one data processing terminal 2 at a time. Yes, users can obtain multiple hard copies at once.

Further, when printing a plurality of print data at a time as described above, a plurality of print data can be laid out so as to minimize the unprinted area if desired, so that wasteful consumption of the roll sheet is prevented. Can be prevented. Further, since the print data is automatically deleted after a preset time elapses, unnecessary print data does not remain in the printer device 3 and the user can print out only necessary print data. Can be.

In addition, when the print data is automatically deleted as described above, a guidance message for data deletion is notified to the user by e-mail xx minutes before the deletion.
The user can input a print output to the printer device 3 before necessary print data is deleted.

In particular, since the guidance message as described above is transmitted in correspondence with the e-mail address, for example, the user transmits print data from the shared data processing terminal 2 and then moves to his / her desk. Even in this case, the guidance message can be received by the data processing terminal 2 of the own desk, and even if the print data is deleted, the guidance message can be confirmed after the fact.

The present invention is not limited to the above-described embodiment, but allows various modifications without departing from the gist of the present invention. For example, in the above embodiment, the print ID is assigned to each user, and the printer 3 prints out a plurality of print data at a time in response to the input operation of the print ID. And print data to be printed out by the user.
It is also possible to make it selectable by D.

Further, in the above embodiment, the CPU 10 is executed in accordance with a control program preset as software.
1 and the central control unit 201 operate to realize various units of the data processing terminal 2 and the printer device 3. However, it is also possible to form each of these various means as unique hardware, and it is also possible to store a part of the means as software in a memory and form a part as hardware.

In the above embodiment, it is assumed that software for implementing various means of the printer 3 is fixedly installed in the central control unit 201. Similarly, it is also possible to supply and set software from outside.

In the above embodiment, when the data processing terminal 2 is started, the software stored in the HDD 105 in advance is copied to the RAM 104.
It is assumed that the CPU 101 reads the software stored in the HDD 10.
5 to be used by the CPU 101,
It is also possible to write fixedly in the OM 103 in advance.

Further, software is written in the information storage medium FD 106 or CD-ROM 108 which can be handled alone, and the FD 106 and the RAM 104
It is also possible to install software in the FD1 or the like without executing such an installation.
