  FIGS. 3A and 3B are block diagrams for explaining the client device 1 and the printer 3 in terms of this function. Since the configuration of the client device 2 is the same as that of the client device 1, the description thereof is also omitted in FIG.

Hereinafter, these means will be described in detail.

  The print data receiving unit 3a is a unit that receives the print data created in the page description language transmitted from the client devices 1 and 2, and outputs the received print data to the print control unit 3b.

  The print control unit 3b stores the received print data in an internal storage unit, and manages the stored print data for each print job, and controls the entire printer 3. The print data is output to the print image creation means 3c under the control of the print control means 3b.

  The print image creation unit 3c is a unit that analyzes the print data output from the print control unit 3b, and generates print image data as drawing data such as bitmap data by analyzing the page description language. In this embodiment, a page memory method is used as a print image creation method. In this method, a memory for one page of printing paper is allocated to a print image, and the created print image is printed.

  The print image storage means 3d is a means for storing the print image data generated by the print image creation means 3c, and outputs the stored print image data to the printing means 3e based on an instruction from the print control means 3b. To do.

  The printing unit 3e is a unit that executes printing by an electrophotographic method or an inkjet method used for a laser beam printer or the like, and forms an image on a recording material based on the print image data.

  The error detection unit 3f is a unit that detects an error in each process from data reception to printing, and outputs the detection result to the error information transmission unit 3g.

  The error information transmission unit 3g is a unit that transmits error information to the client devices 1 and 2, and in this embodiment, print image data at the time of error detection is read from the print image storage unit 3d, and the print image data is converted into an error. Send as information. Details will be described later.

  The transmission source detection means 3i is a means for detecting from which client device the print job is transmitted for each print job. When transmitting the error information as described above, the transmission of the print job is transmitted. The original is transmitted to the error information transmitting means 3g.

  Next, the client device 1 will be described. As shown in FIG. 3B, the client device 1 executes the print data creation unit 1a, the print data transmission unit 1b, the print image reception unit 1c, and the print image display unit 1d by executing the installed control program. Function as. Hereinafter, the print data creation unit 1a, which will be described in detail with respect to these units, is a unit that creates print data in a page description language, and outputs the created print data to the print data transmission unit 1b.

  The print data transmission unit 1 b is a unit that transmits the print data to the printer 3 via the network 4.

  The print image receiving unit 1c is a unit that receives the error information transmitted from the printer 3 via the network 4, and outputs the received error information to the print image display unit 1d.

  The print image display means 1d is a means for displaying print image data as error information transmitted from the printer 3 when an error is detected as described above.

  Next, a printing process including display of error information in the present embodiment will be described based on the flowchart of FIG.

  First, the print data created in the page description language by the print data creation unit 1a of the client device 1 is transmitted via the network by the print data transmission unit 1b and received by the reception unit 3a of the printer 3 (step S1). . Next, the received print data is temporarily stored in the memory in the print control unit 3b, and is output to the print image creation unit 3c under the control of the print control unit 3b. Then, the print image creating means 3c develops the print image data into bitmap data, and the print image data is stored in the print image storage means 3d (step S2).

  The expansion into the bitmap data is performed by analyzing the page description language by the CPU 16 functioning as the print image creation means 3c by executing the emulation program. If the print data created in the page description language itself is defective, an error may be detected by the error detection means 3f during this development process.

  In addition, when the print data is complicated, an error of memory shortage may be detected by the error detection means 3f during the expansion.

  As countermeasures against such errors, in the former case, it is conceivable to change the print data so as not to hit the defective part of the emulation program, or to review the page description language. In the latter case, the print data is changed. It is possible to reduce it.

  For any error, if the location where the error has occurred can be specified, the above-described handling process can be performed quickly.

  Therefore, in this embodiment, not only the error occurrence information is simply notified to the client devices 1 and 2, but also the print image data when the error occurs is transmitted to the client devices 1 and 2, and the client devices 1 and 2 transmit the print image data. Configured to display.

  Therefore, it is determined whether or not an error has occurred during print image creation by the error detection means 3f (step S3). If an error is detected (step S3; YES), the print image storage means at the time of error detection is determined. The print image data stored in 3d is transmitted to the client device 1 or the client device 2 (step S7). This transmission destination is the transmission source of the print job that was being executed when the error was detected, and information on the transmission destination is output from the transmission source detection means 3i to the transmission means 3g. When the receiving unit 3a receives a print job, the transmission source detection unit 3i detects the transmission source of the print job and stores it in association with the print job. Then, when transmitting the print image data as the error information, the transmission source associated with the print job being executed at that time is transmitted to the transmission unit 3g.

  On the other hand, if no error has occurred during creation of the print image data (step S3; NO), it is determined whether or not the printing means 3e is ready for printing and printing can be started (step S4). When printing can be started (step S4; YES), printing is performed by the printing unit 3g based on the print image data stored in the print image storage unit 3d (step S5).

  Further, since there is a possibility that an error such as a paper jam or out of toner or ink may occur even during printing, it is determined whether or not the occurrence of an error during printing has been detected by the error detection means 3i. (Step S6).

  As a result, if it is determined that no error has occurred (step S6; NO), the process is terminated. If it is determined that an error has occurred (step S6; YES), the print image at that time is displayed. Data is transmitted to the client device 1 or the client device 2 (step S7). This process is similar to that described above.

  The print image as error information is displayed on the display as the print image display means 1d of the client apparatuses 1 and 2 as shown in FIG.

  In this example, the image to be printed is the image shown in FIG. 5 (a), whereas the image displayed on the display is a diamond-shaped image 5 as shown in FIG. 5 (b). Only the stage of the triangular image 5 ′ is expanded.

  Therefore, the user can recognize that the expansion into the bitmap data has not been completed and an error has occurred during the creation of the print image by viewing the print image.

  Possible errors that may occur during print image creation are insufficient memory, a malfunction in the emulation program, or a problem in the print data itself, but a problem in the emulation program or the print data itself. If there is, a print image is not formed at all or a print image completely different from the print data is formed. In this case, it can be estimated that an error of insufficient memory has occurred.

  As described above, by providing information about the print image data when an error occurs, it is possible to quickly and easily pursue the cause of the error and further investigate the countermeasure.

  In addition, since the display of the print image as the error information is performed by the client devices 1 and 2, it is possible to quickly take measures against the error.

  However, as in the conventional example, if the configuration is such that the print image at the time of error occurrence is printed, it is necessary for the user to visit the installation location of the printer 3, and the installation locations of the client devices 1 and 2 and the printer 3 are If you are far away, it is impossible to respond quickly to errors. Furthermore, in the configuration in which a print image is printed when an error occurs, the print image cannot be printed if an error occurs during printing.

  On the other hand, in this embodiment, when the print image displayed as the error information is normal, the expansion process is performed normally, and it is notified that an error has occurred during printing. it can. Then, after recovering from the error, it is possible to quickly notify from which image printing should be resumed. In particular, such information is very effective when printing over a plurality of pages.

  However, to reduce the memory usage, instead of allocating the memory for one page of printing paper to the print image, use one or more blocks of memory smaller than one page of printing paper to expand the print image in each memory block. However, when the so-called band-type print image creation is performed in which the memory is used to perform printing for one page, a message indicating not only the print image data but also the error type is included as error information. It is preferable to be displayed.

  When the band method is used, even if the expansion process is performed normally, if an error occurs during printing, a print image for one page may not be formed, and at which stage the error occurs. This is because it becomes unclear.

  When the band method is adopted, the print data described in the page description language is sequentially expanded and the print image at the time of the error occurrence is transmitted by using the memory similarly to the print processing. .

  The message indicating the type of error may be used not only when the band method is used but also when the page memory method described in this embodiment is used. This is because the display of the message allows the user to clarify the cause of the error and take countermeasures more quickly.

  In this embodiment, the print image is always displayed on the client device when an error occurs. However, the present invention is not limited to this, and is configured to be displayed by the user's selection. May be.

  For example, when print image data as error information is received by the host device, only the fact that an error has occurred is displayed on the display as display means, and the print image can be displayed by a keyboard or mouse as information input means. It may be configured to be controlled by the CPU 10 as the error information display control means so that the print image is displayed only when it is selected.

  According to such a configuration, when the user is performing some work on the display, the error information can be appropriately notified without interfering with the work.

  Further, in the present embodiment, the description has been given by using an example using a client device and a network printer connected via a network, but the present invention is not limited to this, and a host device such as a single personal computer or the like.
