  FIG. 3 shows the number of driver part generation data structures, and FIG. 3A shows an outline of driver generation print data. This data is sent in the order of the PDL command group and the character information management table in the printer transport direction.

Here, the character information management table is formed side by side from the first page as shown in the page management table of FIG. Furthermore, the row management information table is formed side by side sequentially from the first row for each page, as shown in FIG.
In addition, the character information variable is formed by information as shown in FIG.

FIG. 4 is a flowchart for explaining an operation outline in the printing apparatus according to the present invention.
In other words, this embodiment is realized by providing functions corresponding to both the printer printer driver on the PC as the host 21 and the printer 22.

  In this figure, when printing from an application on the PC (21), the user prints data after setting the editing function to ON in the printer driver setting in S1.

  Next, in S2, the printing result is confirmed, and when a correction portion is found, the editing mode is designated on the operation panel 2 of the printer 22 in S3.

  Then, the printer that has entered the edit mode can select a job file. In step S4, a printed job file is selected.

Thereafter, after specifying the job file, in step S5, the page number having the correction portion and the coordinates of the corresponding character are specified continuously from the operation panel 2.
When the operation panel 2 has a graphic display function at the time of specifying the coordinates, the overview of the page is displayed on the panel 2 and the coordinates are specified by pointing to the character of the corresponding character.

  Subsequently, a new character code to be replaced is set from the panel 2 (S6, S7).

  Then, as shown in S8, the printer 22 performs printing by replacing the character at the corresponding coordinate of the corresponding page of the page specified from the panel 2 with the new character specified in the previous procedure.

  The individual operations of the printer driver of the PC 21 and the printer 22 will be described below.

That is, FIG. 5 shows the operation on the printer driver side.
First, when printing is performed from the application through the printer driver, as shown in S11, the setting of the “editing function” newly provided in the driver is confirmed. If the setting of the “editing function” is not performed, S23 is performed. Proceed to, print as normal print data, and finish.

  If the “editing function” is designated, the “character information management table” shown in FIG. 3 is secured on the RAM 5 as an initial setting in S12. In this character information management, each piece of information is connected by a pointer.

  In S13, the DDI command received from the application is inspected. In S14, it is determined whether the data is character data.

In S15, if it is character data, the setting of “editing function” is inspected. In S16, if “editing function” is set, it is inspected whether the immediately preceding drawing character is in the same page.
If it is not the same page, the “page management table” is additionally updated and written as new page data in S17.

If it is not the same page, the next processing is continued as it is.
In the line inspection in S18, the Y coordinate value of the character information set immediately before from the “character information management table” is compared with the Y coordinate of the character to be drawn. , S19 additionally stores in the current “line management table” {see FIG. 3C}.
If the Y coordinate is different, it is regarded as another line, and the process proceeds to S22, where a new line table is added, and character information management is set there.

Here, when setting character information management, drawing information of character position X, Y coordinates, character code, character width, and character height, which is information related to characters, is extracted from the driver, and character variables {(d) of FIG. After setting to Reference}, this variable is set in the row table.
At the same time, the DDI command related to this character is processed as a normal command in S20, and a PDL command is generated and transmitted to the printer in S21.

After processing the characters, the process returns to the inspection of a new DDI command {see (c) in FIG. 3}, and thereafter, these operations are repeated until all the DDI commands are processed.
After processing all DDI commands and transmitting all normal PDL data to the printer, in S24 and S25, the "character information management table" created so far is transmitted to the printer and the job file is closed.

The operation on the printer 22 side is as shown in FIG.
First, in S31 in FIG. 6, an “editing function” is prepared in the menu of the operation panel 2 of the printer 22.

  When this “editing function” is set, the sent PDL data + character information management table job is automatically cached and stored in the HDD 11 as a job file in S32.

In S33, the user selects a corresponding job file from the operation panel 2 based on the user name / date / job name.
Subsequently, in S34, the page number on which the character to be edited is printed is input, the X and Y coordinates of the character are input in S35, and the code of the character to be replaced is input in S36.

  In step S37, based on the coordinate information input on the panel 2, the corresponding character information is searched from the “character information management table” (see FIG. 3) in the job file, and the page number and character code information are retrieved. To get.

In S38, the controller continues to PDL command processing for the designated job file.
In S39, the job file is skipped up to the number of previously acquired pages, and the PDL command is analyzed / executed from the point where the corresponding page is reached.

  In S40, it is determined whether or not the command to be processed is character data. If there is no character data, drawing processing is performed as a normal command in S44, and the processing of the next PDL command is continued.

  If it is character data, the process proceeds to S41, where the current print pointer is compared with the coordinates previously designated on the panel (S35). "Information" is retrieved from the character information management table.

  In S43, the character to be printed is discarded, and the character code previously specified on the panel is drawn based on the read character information (S36).

  When the analysis / drawing of all the commands that repeat the above processing until all the data in the page has been processed is finished (S39), the page is ejected, and the processing of the “editing function” ends.

  According to the printing apparatus having the above configuration, both the printer driver and the printer are equipped with an editing function. When printing is executed by the driver, character information management such as character code / printing position / character size / number of pages from character data is performed. The collected character information management table is created, transferred to the printer 22 at the same time as the PDL command group, and printed.

At this time, the printer 22 can call the job on the panel 2, edit the characters by specifying the number of pages, the coordinates of the characters, and a new character code, and perform printing.
Therefore, according to such a configuration, in a printer that is connected to the network and is away from the PC, it is possible to immediately correct typographical errors and omissions noticed by looking at the printed matter and reprint only the corresponding page. Can do it.

In the printer 22, by designating the number of pages / printing position and a new character code from the panel 2, it is possible to replace the original character with the newly designated character and print only the corresponding page.
According to such a configuration, since it is possible to change the job data registered in the past, the editing can be performed without the original application data on the PC 21.

  Note that the present invention is not limited to the structure described in the above-described embodiment, and it goes without saying that the shape, structure, and the like of each part constituting the printing apparatus using the PC 21 and the printer 22 can be appropriately modified and changed.
