Therefore, the data management determining means 37
Has a storage / double-sided / Nup registration table (hereinafter simply referred to as a registration table) 37a.

In the registration table 37a, the recognition result of the operation code notified from the operation / identification code recognition means 32 is registered in a table format. That is, the registration table 37a indicates, for each piece of code data received by the I / F means 31, what kind of operation code is assigned to each piece of code data, for example, the double-sided printing mode or the Nup output mode, and further, the accumulation mode. It is for managing whether or not it is specified. In the registration table 37a, these are managed until the output by the image forming output unit 36 is completed.
That is, the operation code of the stored data in the storage unit 35 is also managed.

Further, the data management judging means 37 includes an I / F
When the storage mode is designated in the operation code assigned to the code data when the means 31 receives the code data, it is determined whether or not the stored data is stored in the storage means 35. It is. However,
The data management determining means 37 determines whether or not already stored data having the same content (same mode) as the operation code received by the I / F means 31 is stored and stored. Then, as a result of this determination, the storing means 3
If there is already stored data of the same mode in 5, the data management determining means 37 gives an instruction to the output control means 34 to perform the processing described below.

In accordance with an instruction from the data management determining means 37, the output control means 34 stores the stored data of the same mode in the storing means 35, and the developed data developed by the developing means 33 after being received by the I / F means 31. In addition, processing necessary for double-sided printing or Nup output is performed on these, and the stored data and expanded data after this processing are output to the image forming output unit 36.

Here, in the printing apparatus 1 configured as described above, an example of the operation when the code data transmitted from the host apparatus 2 is output on a recording medium will be described in detail with reference to the flowchart of FIG. I do.

When there is a print data output request from the host device 2, the I / F unit 31 receives a plurality of pages of code data from the host device 2 as one print data, and further adds the code data to the code data. The received operation code is received (Step 101, hereinafter, step is abbreviated as S). When the I / F unit 31 receives the code data and the operation code, the operation / identification code recognition unit 32 extracts and recognizes the received operation code (S102).
It is determined whether or not the accumulation mode is specified in the operation code (S103).

If the storage mode is not specified, the printing apparatus 1 performs a normal printer output on the code data received by the I / F means 31, that is, the same printer output as that of the conventional printing apparatus (S104). ). That is, the developing means 33 performs image developing on the code data, and the output control means 34 performs processing for double-sided printing and Nup output as necessary, and the resulting developed data is subjected to image formation. The output means 36 outputs. On the other hand, if the accumulation mode is designated, the data management judgment means 37 checks the contents registered in the registration table 37a (S105), and stores the accumulated data in the same mode as the operation code for which the accumulation mode is designated. Is storage means 3
5 is determined (S10).
6).

If there is no stored data of the same mode in the storage means 35, the printing apparatus 1 outputs the code data received by the I / F means 31 in accordance with the operation code assigned to the data (S107). That is, the developing unit 33 performs image expansion on the code data, the output control unit 34 performs processing for double-sided printing or Nup output according to the operation code, and outputs the obtained developed data to the image forming output. The means 36 outputs.

If there is already stored data of the same mode in the storage means 35, the output control means 34 extracts the stored data from the storage means 35 (S108), and the I / F means 31 receives this. After that, it is combined with the developed data developed by the developing means 33. Then, when the output control unit 34 performs a process for double-sided printing or Nup output on these, the image forming output unit 36 outputs the image as a visible image on a recording medium (S109).

At this time, the above steps (S107,
In step S109), the output control unit 34 performs processing for double-sided printing or Nup output in the expanded data expanded by the expanding unit 33 or in the data obtained by combining the already stored data and the expanded data. It is determined whether there is a page to be output together with the margin page (S11).
0). If there is no page to be output together with the margin page, the image formation output unit 36 outputs these data as they are, and the data management determination unit 37 further registers the registration table 3
Clear (delete) the corresponding operation code in 7a (S
111).

On the other hand, if there is a page to be output together with the blank page, the data management judging means 37 does not output the development data for the page by the image forming output means 36,
The storage to be stored by the storage unit 35 as the stored data is registered in the registration table 37a (S112). Then, the storage unit 35 stores and stores the expanded data for the page as already stored data (S113).
In addition, the accumulation unit 35 may store and accumulate not only the decompressed data of the page to be output together with the blank page but also the decompressed data of another page obtained together with the decompressed data as already stored data. . That is, the stored data may be not one page but one print data.

Thereafter, when there is a new print data output request from the host device 2 or job management
When the output of new print data is scheduled by the CONT 23, the printing apparatus 1 repeats the above steps again.

That is, in the printing apparatus 1, if the storage mode is specified in the operation code from the host apparatus 2, it is determined whether or not there is stored data at the time of inputting the print data. For example, the stored data and the input print data are output together. However, if the accumulation mode is not specified, even if there is already accumulated data, this is not output together with the input print data. That is, the storage mode input by the host device 2 is for causing the printing device 1 to perform such a processing operation.

As described above, the printing apparatus 1 according to the present embodiment
When the storage mode is specified, the stored data and the input print data are output together, so even if there is a page to be output together with a blank page in the input print data, In addition, a blank page, that is, a useless area does not occur on the recording medium. Therefore, for example, three pages of print data or 4
When print data for five pages is output at the time of up output, the last page of these print data may be output together with a blank page without performing a complicated operation to combine the print data into one in advance. Since there is no recording medium, waste of the recording medium can be eliminated, and saving of the recording medium can be easily and reliably realized.

Further, in the printing apparatus 1 of the present embodiment, unless the accumulation mode is designated, the stored data and the print data are not output together, so that the output is performed together with other print data. The print data that the user does not want to print can be output alone as in the conventional print data. Therefore, it is possible for the user to select the output destination, which is more convenient than before.

Next, a case where a function as an output instruction means in the present invention is provided in addition to the above-described printing apparatus 1, that is, a printing apparatus according to the second aspect of the present invention will be described. In the printing apparatus 1, the output instruction means is realized by a function described below.

On the printer property (see FIG. 3) displayed on the host device 2, an item for specifying the forced output e is provided. Then, when this forced output e is specified,
In the printing apparatus 1, the I / F unit 31 receives this, and the operation / identification code recognition unit 32 recognizes the content and notifies the data management determination unit 37. Upon receiving a notification from the host device 2 that forced output has been specified, the data management determination unit 37 performs image formation on the stored data in the storage unit 35 regardless of whether new print data is input. An instruction is given to the storage means 35 so as to be output by the output means 36. The item for specifying the forced output may be provided on the UI 11 of the printing apparatus 1 instead of the printer property.

With this output instructing means, the printing apparatus 1 can output the stored data on the recording medium regardless of whether new print data is input. In other words, if forced output is specified before new print data is transmitted from the host device 2 to the printing device 1, the new print data and the stored data are not combined, so that these can be output individually. become. Furthermore, if the forced output is designated, the stored data can be output even when there is no new print data input, so that the output of the stored data does not have to wait.

As the output instructing means, the data management judging means 37 has a function of measuring the elapsed time after the storage means 35 stores and stores the already stored data, and the data management judging means 37 has a function of measuring the elapsed time after the lapse of a predetermined time. The function may be realized by providing a function of giving an instruction to output accumulated data. In this case, even if there is no input of new print data after the storage unit 35 stores and stores the stored data, the stored data is output after a certain period of time. There is no such thing as being done.

Next, a case where a function as data management means in the present invention is provided in addition to the above-described printing apparatus 1, that is, a printing apparatus according to the third aspect of the present invention will be described. In the printing apparatus 1, the data management judging means 37 has a function as a data managing means, so that it corresponds to an identification code for identifying print data.

The identification code is a code that the host device 2 adds to the print data when the host device 2 transmits the print data to the printing device 1 and transmits the print data. The user ID and group ID given to the print data, or the data ID input together with the print data when the print data is input.

In the printing apparatus 1, upon receiving the identification code from the host apparatus 2, the operation / identification code recognizing means 32 recognizes the contents thereof in the same manner as the operation code, and the data management determining means 37 further stores this in the registration table 37a. It is designed to be registered and managed. In the printing apparatus 1 having such a function, the print data from the host apparatus 2
Are output according to the procedure shown in the flowchart of FIG. However, here, only the differences from the already described operation example (see FIG. 4) will be described.

When the I / F unit 31 receives the code data, the identification code, and the operation code from the host device 2 (S201), the operation / identification code recognition unit 32 extracts and recognizes the identification code (S202). Then, the operation code is extracted and recognized (S203). If the storage mode is specified in the recognized operation code (S
204), the data management determining means 37
Check the contents registered in 7a (S206),
It is determined whether or not the stored data having the same operation code and the same identification code exists in the storage unit 35 (S207).

If there is no stored data having the same operation code and the same identification code in the storage means 35, the printing apparatus 1 adds the code data received by the I / F means 31 to this. Output according to the operation code (S208). On the other hand, if there is already stored data having the same operation code and the same identification code in the storage means 35, the output control means 34 takes out the stored data from the storage means 35 (S209) and I / F means 3
1 is received, the print data is output together with the decompressed data decompressed by the decompression means 33 (S210), as in the case described above.

As described above, in the printing apparatus 1 having a function as a data management unit, when the output control unit 34 combines the stored data and the developed data, the identification code for the stored data and the developed data These codes are combined only when the identification codes match. Therefore, when the printing apparatus 1 is used by a plurality of host devices or a plurality of users, the output control unit 34 can perform double-sided printing and Nup output collectively for each user and each document type, for example. . That is,
Even if the accumulation mode is set, it is possible to separately output print data that is not desired to be combined, for example, for each user and for each document type, resulting in double-sided printing or Nup output mixed with other print data. Can be prevented.

Next, a printing system according to the present invention, that is, a printing system according to the present invention will be described. FIG. 6 is a block diagram illustrating a hardware configuration of the printing system according to the present embodiment. As shown in FIG. 6, in the printing system according to the present embodiment, the operation / identification code CONT28, the Nup conversion / double-sided CONT29, and the image storage CONT30 are provided not in the printing apparatus 1a but in the host apparatus 2a. is there.

That is, the host device 2a is provided with functions as an accumulation instruction unit, a determination unit, and an output control unit in the present invention. More specifically, in the host device 2a, when the accumulation mode is designated, the code data to be output to the printing device 1a includes:
If there is a page that will be output together with the margin page,
An instruction is given to the disk CONT 24 of the printing apparatus 1a so that the code data of the page is stored as stored data. Further, when transmitting the code data to the printing apparatus 1a, if the storage mode is designated for the code data in the host apparatus 2a, the printing apparatus 1a
It is determined whether the data storage memory 12 has already stored the stored data. Furthermore, in the host device 2a, if the stored data is stored in the data storage memory 12, the stored data and the code data to be transmitted to the printing apparatus 1a are combined, and these are printed on both sides or output as Nup. Thus, the instruction is given to the printing apparatus 1a.

In this printing system, by providing these functions in the host device 2a, the same effects as those of the printing device 1 described above can be obtained even if the printing device in the system is a conventional one. . Further, in the printing system, realization of these functions can be achieved more easily than in the case where the printing apparatus 1 is provided, from the viewpoint of the performance (hardware configuration, software configuration, and the like) of the host device 2a.

In this printing system, one or both of the host device 2a and the printing device 1a are provided with a function as output instructing means in the present invention, similarly to the case of the printing device 1 described above. Then, the stored data can be output on the recording medium regardless of whether new print data is input.

Further, in this printing system, the host device 2a is provided with a function as a code adding means for adding an identification code to the print data to be sent to the printing device 1a, and only the stored data and the code data whose identification codes match are stored. A data management means for combining them may be provided. In this case, similar to the case of the printing apparatus 1 described above,
For example, for both users and document types, double-sided printing and N
Up output can be performed.

In the above embodiment, the case where the present invention is applied to a printer connected to a personal computer has been described, but the present invention is not limited to this. For example, the present invention can be applied to any apparatus that outputs a plurality of pages of print data on one recording medium, such as a digital copying machine, a facsimile machine, or a multifunction peripheral.

[0057]

As described above, the printing apparatus and the printing system of the present invention output the stored data and the input print data together when the storage mode is designated. Even if the print data includes a page to be output together with a blank page, a blank page, that is, a useless area does not occur on the recording medium. Therefore, for example, when print data for three pages is output during two-sided printing or print data for five pages is output when outputting four ups, these operations can be performed without performing a complicated operation to combine the print data into one in advance. Since the last page of the print data is not output together with the blank page, it is possible to eliminate waste of the recording medium and to save the recording medium easily and reliably.
