Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus capable of processing a plurality of control command systems.

[0002]

2. Description of the Related Art Conventionally, when processing a plurality of control command systems as in this type of apparatus, the printer engine is controlled according to the control command system corresponding to each host, and one printer can control various hosts. It is configured so that it can function as a corresponding printing device.

Such a printing apparatus is provided with one counter for managing the number of discharged sheets, and the counter integrally manages the number of discharged sheets.

[0004]

Therefore, since the value counted by the counter is the total number of discharged sheets regardless of the connected host, it is possible to manage the number of discharged sheets for each host. However, there is a problem in that a system connected to a plurality of hosts cannot manage charges.

The present invention has been made to solve the above problems, and manages the number of discharged sheets for each host by individually managing the number of discharged sheets for each executable control command system. It is an object of the present invention to provide a printing apparatus capable of performing charge management in a system connected to a plurality of hosts.

[0006]

A printing apparatus according to the present invention analyzes data transmitted from a plurality of or a single data source to identify a plurality of control command system types, and an identification of the identification means. A plurality of counting means for counting the number of discharged sheets is provided for each control command system executed based on the result.

[0007]

In the present invention, when the data is transmitted from the data source, the identifying means analyzes the transmitted data to identify a plurality of control command system types, and each counting means determines each one based on the identification result. It is possible to count the number of discharged sheets for each control command system and manage the number of discharged sheets for each host.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram for explaining the structure of a printing apparatus showing an embodiment of the present invention.

In the figure, 1 is a data source such as a host computer, 2 is an input buffer for storing input data, 3
Is a CPU which analyzes the data input from the input buffer 2 in accordance with the control procedure shown in FIG. The CPU 3 comprises a RAM 4 which is a work area and a ROM 5 which stores a program corresponding to the control procedure shown in FIG. Reference numeral 3a is a first counter (native counter) which counts up the number of sheets discharged by the printer 9 when the control system is in the native mode. A second counter (emulation counter) 3b counts up the number of sheets discharged by the printer 9 when the control system is the emulation mode. In addition,
The number of counters is not limited to this embodiment.

An image memory 6 stores an output image for one page. A pattern memory 7 stores a character pattern corresponding to a character code. A printer interface 8 transfers the output image data stored in the image memory 6 to the printer 9. Printer 9
Performs print processing based on the output image data received via the printer interface 8.

In the printing apparatus constructed as described above,
When data is transmitted from the data source 1, the identification means (CP
U3) analyzes the transmitted data to identify a plurality of control command system types, and based on the identification result, each counting means (first counter 3a, second counter 3b) ejects each control command system. It is possible to count the number of discharged sheets and manage the number of discharged sheets for each host.

The control sheet number management processing operation for each control system in the printing apparatus according to the present invention will be described below with reference to the flow chart shown in FIG.

FIG. 2 is a flow chart showing an example of the number-of-sheets management processing procedure for each control system in the printing apparatus according to the present invention. In addition, (1) to (15) indicate each step.

When data is transmitted from the data source 1, the processing is started and the data is fetched from the input buffer 2.
(1). Next, it is judged whether the fetched data is a control command (2), and if YES, it is judged whether the control command is a native command (3). If YES, the identification flag is turned ON.
Then (4), analysis corresponding to the native instruction is performed (5), and the process proceeds to step (10) and thereafter.

On the other hand, if the judgment in step (3) is NO, it is judged to be the emulation mode and the identification flag is set to O.
The FF is performed (6), the analysis corresponding to the emulation instruction is performed (7), and the process proceeds to step (10) and thereafter.

On the other hand, if the determination in step (2) is NO, the character pattern corresponding to the character code is read from the pattern memory 7 (8), and the read pattern is written in the image memory 6 (9). Next, it is judged whether or not there is a page break (10), and if NO, the process returns to step (1) and YE
If it is S, the image memory 6 is closed and output to the printer 9 through the printer interface 8 (11). Next, after confirming that the page is output, it is determined whether or not the identification flag is currently in the ON state (12). If YES, the content of the first counter 3a is incremented by "1".
(13), it is judged whether or not it is a data end (15), the process is ended if YES, and the process returns to step (1) if NO.

On the other hand, if the determination in step (12) is NO, the content of the second counter 3b is incremented by "1".
(14), it is judged whether or not it is a data end (15), the process is ended if YES, and the process returns to step (1) if NO.

In the above embodiment, the usage pattern in which different control command systems by a plurality of users are processed from the single data source 1 is hypothesized, but the same applies when connected to a plurality of data sources.

[0019]

As described above, according to the present invention, when data is transmitted from the data source, the identification means analyzes the transmitted data to identify a plurality of control command system types, and based on the identification result. Since each counting unit is configured to count the number of discharged sheets for each control command system, it is possible to manage the number of discharged sheets for each host, and to manage the charge in a system connected to multiple hosts. There is an effect that can be performed.
