BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a print control apparatus for analyzing print control information input from an information processing apparatus such as a host computer and outputting a control instruction dump, a data processing method of the print control apparatus, and a computer. The present invention relates to a storage medium storing a readable program.

[0002]

2. Description of the Related Art Conventionally, a print control device for controlling a printer section performs an analysis process for outputting a print control command (hereinafter, a command) input from a host in accordance with the rules of the command. ing. Further, the print control device performs analysis processing (hereinafter, emulation) of commands of different types in addition to the native commands of the print control device. Further, the print control device includes:
In addition to the control instruction for printing, the control instruction (JL command) for changing the printing environment is analyzed as a general concept of the control instruction.

[0003] The print control apparatus may have a function of outputting the command input from the host from the printing unit without performing analysis processing for image output (hereinafter, a dump function). .

[0004] Such a dump function includes a hexa-dump function for outputting input information in hexadecimal code, and a more advanced function such as a character or a symbol based on a rule corresponding to the type of each command. Output with intelligent dump function.

[0005]

Since the conventional print control apparatus is configured as described above, when the output is performed in the dump mode, the emulation can be switched only manually by the user before the dump output. When performing intelligent dump of data containing a mixture of jobs of multiple command types, only specific commands selected by the user could be correctly interpreted, and other types of commands did not produce the desired output results. .

Also, in a print control apparatus having automatic emulation switching means, when performing intelligent dump of data in which a plurality of command type jobs are mixed, the result of the dump is continuously output even if emulation switching occurs.

Further, in a print control apparatus having automatic emulation switching means, when performing intelligent dump of data in which a plurality of job types are mixed, intelligent dump is performed for all command type information. Could not perform an intelligent dump on the information for the particular command type selected.

Further, when a print environment change command (JL command), which is a general concept of a normal command, is input from the host, no special processing is performed on the JL command, so that the JL command has an effect. There is a problem that it is difficult to determine the range of the error.

The JL command is analyzed and the JL command is analyzed.
In a print control apparatus including a means for shading the effective range of a command, when there are a plurality of JL commands, shading is performed in the same pattern, so that it is difficult to determine the effective range of each command. There was a problem.

The present invention has been made to solve the above problems, and a first object of the first to seventeenth inventions according to the present invention is to provide a control language system of an input control command. The second object of the present invention is to replace the control command of each control language system with an appropriate pattern and to output the same by switching dump processing by identifying the control language system. By switching the dump processing by comparing with the language system, the control instruction of the specified control language system can be replaced with an appropriate pattern and selected and output, and the output of the control instruction of the non-designated control language system can be output. The ability to output each image, third
The purpose of the present invention is to compare a designated control language system with a control language system of an input control instruction and to determine whether the control instruction is an output environment change instruction when switching dump processing, and A print control apparatus and a data processing method of the print control apparatus, which can obtain a dump output result that can easily identify a dump output form of another control instruction and an output environment change instruction by respectively changing the dump output form of the print control apparatus.

Next, in step (3), it is determined whether or not the operation mode has been switched to the dump mode by the operation panel 1012. If it is determined that the dump mode has not been instructed, the data sent from the host computer 3000 is transmitted to the step (3). In 4), processing such as data reception, command analysis, and rasterization is performed, and output as a normal image.

On the other hand, if it is determined in step (3) that the dump mode has been instructed, print data is received from the external host computer 3000 in step (5), and the print data is stored in the input unit 18. Then, data of a certain size is read from the input unit 18. The data is temporarily stored in a part of the work memory in the RAM 19. Then, in step (6), the type of command is interpreted according to a predetermined rule such as pattern matching, and the process branches according to the result.

In the following step (7), if the data analysis determines that the data is a LIPS command,
In step (8), a LIPS dump is performed.

If it is determined in step (7) that the data is an ESC / P by data analysis, an ESC / P dump is performed in step (9).

Next, in step (10), the received data is terminated, that is, unprocessed received data is checked. If it is determined that the received data exists, the process returns to step (6) to analyze the data again.

On the other hand, if it is determined in step (10) that unprocessed data no longer exists, a dump printing process is performed in step (11), and the process returns to step (3) to process the next data. .

Thus, even if the command type of the data received from the host computer 3000 is changed after the dump mode is instructed, a different dump process matching the analyzed command is executed, and an appropriate dump print result is obtained. Can be obtained.
