Abstract

<P>PROBLEM TO BE SOLVED: To suppress the printing of an unnecessary error page resulting from the disagreement of a communication mode in a printer which receives and prints data constituted of a page description language. <P>SOLUTION: A means which judges the content of an error is provided in an error page processing section to discard data on and after the occurrence of an error resulting from the disagreement of the communication mode. At the same time, a means which performs reprinting when the reprinting of the data is possible by switching the communication mode to a suitable one is provided to perform reprinting when required, so that a normal printing result is yielded. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to an error page processing method for a printer that prints data composed of a page description language.

  Some printers that can print data configured in a page description language have a function of printing an error page when data that the printer cannot process is received. There are various conditions for generating an error. Among them, if data is transmitted in a communication mode that is not intended by the user, it may become meaningless data for the printer, resulting in an error. .

  A typical example is a printer that supports PostScript as a page description language, when data assuming the Adobe binary communication protocol is sent when the printer communication mode conforms to the Adobe standard protocol. It is done. In the Adobe standard protocol, a part of communication data is used for communication control. In the Adobe binary communication protocol, all communication data is handled as print data.

  If the data created by the printer user assumes the Adobe binary communication protocol and the printer is set to a communication mode that conforms to the Adobe standard protocol, some of the data is treated as a communication control character and is not intended by the user. In some cases, a large number of error pages were printed. In addition, when this phenomenon occurred, the data was not printed normally unless an operation by the user was performed.

  As described above, since data is transmitted in a communication mode not intended by the user, the data cannot be printed normally and an unnecessary error page is printed.

  The error page processing unit is provided with a means to determine the content of the error. When an error due to a mismatch in communication mode occurs, the subsequent data is discarded, and when the data can be reprinted, it is switched to the appropriate communication mode. A normal printing result is obtained by providing means for performing reprinting and performing reprinting when necessary.

  The error page processing method of the present invention has an advantage that printing of unnecessary error pages can be suppressed, and an error state can be restored depending on conditions, and printing can be performed normally.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments according to the invention will be described with reference to the accompanying drawings.

  FIG. 2 shows a conceptual diagram of the present invention. Printer B is connected to Host A. Host A transmits data to printer B, and printer B prints the data. In the printer B, there is a postscript processing unit C. When data is described in postscript, the data is processed. If there is an error in the data, an error page is created by the error page processing unit D. In the present invention, the error page processing unit D is implemented.

  FIG. 1 shows the processing contents of the present invention.

  If a postscript error is detected in process 1, the process proceeds to process 2. If the communication mode of the printer does not conform to the Adobe standard protocol, an error page is printed in process 13. When the communication mode conforms to the Adobe standard protocol, it is considered that there is a possibility that data conforming to the Adobe binary communication protocol is not intended, and the process proceeds to the next process.

  In process 3, it is determined whether multiple postscript errors have occurred in the same data file. Normally, when a postscript error occurs due to a mismatch of communication modes, a plurality of postscript errors occur in one data file. Therefore, when a second PostScript error occurs in the same file, it is determined that this is an error due to a mismatch in communication mode. If this is the first error in the same file, an error page is printed in step 13.

  In process 4, it is determined whether or not the corresponding data remains in the printer B in order to investigate whether the data can be reprinted. If the corresponding data remains in the printer B, reprinting is possible, so in step 5, the print data is first discarded. If the error page created by the first postscript error has not been printed yet, this process can prevent unnecessary error page printing.

  Thereafter, in process 6, the communication mode of the printer B is switched to the one conforming to the Adobe binary communication protocol. This prevents postscript errors from occurring repeatedly when the relevant data is reprinted.

  Further, in step 7, the corresponding data is printed. As described above, since the mismatch of the communication modes is resolved at the time of this processing, a postscript error due to this does not occur.

  After printing the data, in step 8, the communication mode is switched to that conforming to the Adobe standard protocol. This process has the meaning of returning the communication mode switched in the previous process 6 to the original state.

  As described above, when a postscript error due to a mismatch in communication modes occurs and data remains in the printer B, it is possible to perform normal printing in an appropriate communication mode.

  If no data remains in the printer B in the process 4, it is determined in the process 9 whether the data can be retransmitted on the host A side. If the data cannot be retransmitted, the reprinting of the corresponding data is abandoned, and all remaining data in the same data file is discarded in processing 14. However, this prevents printing a lot of unnecessary error pages.

  When the data can be retransmitted, the current received data is discarded at step 10 and the print data is also discarded. Then, in the same manner as when data remains in the printer B, the communication mode is changed to one that conforms to the Adobe binary communication protocol in processing 11.

  Thereafter, in step 12, the host A is requested to retransmit data. At this time, the communication mode is set to an appropriate one.

  After that, as in the case where data remains in the printer B, the data is printed in the process 7, and the communication mode is switched to the one conforming to the Adobe standard protocol in the process 8.

  As described above, when a postscript error due to a mismatch in communication modes occurs and data can be retransmitted on the host A side, it is possible to normally print in an appropriate communication mode. Even when data does not remain in the printer B and data cannot be retransmitted from the host A, it is determined that there is a postscript error due to a mismatch in the communication mode, and an unnecessarily large number of error pages are generated. It is possible to prevent the phenomenon of printing.

5 is a flowchart illustrating an embodiment of an error page processing method according to the present invention. It is the conceptual diagram which showed the Example of this invention.
