An emulation program conventionally held in a printer device is collectively stored in a printer server, and a necessary emulation program is downloaded and provided to the printer device when necessary.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a printer apparatus connected to a print server that performs a print job in a network, and executes a print job requested by a client server via the network.
The present invention relates to a control method for switching an emulation program which is a command system to be applied.

[0002]

2. Description of the Related Art A method of sharing a printer device in a network by configuring a network with a plurality of computers, connecting the printer device to a specific computer and defining the computer as a printer server, has already been proposed. Are known.

[0003] Also, since the individual computers, which are client servers constituting the above-mentioned network, usually perform different tasks, the application software applied to these computers is also different. Some command systems are different, and it is necessary to prepare an emulation program corresponding to the command system for the printer device.

The execution of a printing operation of a printer device performed by the conventional technique will be described with reference to FIGS. 5 and 6. FIG.
FIG. 5 is a block diagram showing a configuration according to the related art.
FIG. 6 shows a flow according to the conventional technique.

[0005] The client server B08 transmits a print job instruction to the printer server B06 via the network B09.

[0006] The printer server B06 sends a print job instruction signal that has reached the network control unit B61 to the print job management unit B62 in step S61, and recognizes that the print job instruction has been received.

The driver B63 for emulation is
In step S62, print data is created based on an instruction from the client server B08.

Next, in step S63, the emulation-compatible driver B63 analyzes the created print data, divides the data amount into units set in advance, and divides the first part into the interface unit B6 in step S64.
5 to the printer B07. Further, the continuous data is stored in the print data storage buffer B66.

The control unit B75 of the printer B07 receives the print data via the interface unit B71 in step S71, and proceeds to step S72 to check a necessary emulation program.

If it is determined in step S73 that the emulation program required for the designated printing job matches the emulation program prepared in the control unit B75 of the printer, step S74 is reached.
To execute the designated print job.

If it is determined in step S73 that the emulation program required for the designated printing job does not match the emulation program prepared in the control unit B75 of the printer, the flow advances to step S75. An indication that the emulation-compatible programs do not match is displayed, and the operator operates the operation unit B78.
Emulation-compatible program storage B with more intervention
After selecting the corresponding emulation-compatible program from 77, the flow advances to step S74 to execute the designated print job.

[0012]

As described above, the conventional method of controlling a printer apparatus has the following problems.

1) Since the emulation program is prepared in the printer device, if the type of application software used by the client server increases, the type of emulation program prepared in the printer device increases accordingly, and the memory for storage is increased. Increase.

2) When the application used by the client server is different, it is necessary to switch the emulation program prepared via the operation unit of the printer every time.

[0015]

In order to solve the above problems, the present invention employs the following means.

1) The printer server has a plurality of emulation programs in a built-in memory area, and supplies an emulation program necessary for executing a printing job to the printer device.

By this means, an operation is obtained in which the printer server manages the emulation program required for the printing job.

2) The printer server confirms the emulation program to be used before executing the printing job, selects necessary emulation programs, and supplies the selected emulation programs to the printer device.

By this means, the printer server manages the emulation program necessary for each printing job, and the printer device has an effect that it has only the emulation program necessary for the printing job.

3) The printer server supplies an emulation program selected from a plurality of emulation programs held and managed by the printer server when the power of the printer device is turned on. Specify the required emulation program from the emulation programs provided in advance.

By this means, an effect is obtained that the printer server selects an emulation program necessary for each printing job.

[0022]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention takes the following forms.

1) The printer server has a plurality of emulation programs, and when executing a print job, supplies the emulation program necessary for the execution of the print job from the printer server to the printer device.

By taking this form, an effect is obtained that the emulation program required for performing the printing job is always managed by the printer server collectively.

2) Prior to execution of a print job performed in response to a request from a client server performed via a network, an emulation program necessary for performing the print job is provided from the printer server to the printer device.

By adopting this mode, an effect is obtained that the printer always has only the emulation program necessary for the printing job actually executed.

3) Prior to execution of a print job performed in response to a request from a client server performed via a network, an emulation program stored in the printer is checked. If the emulation program does not match the print job, a necessary emulation program is checked. Replace with

By adopting this form, an effect is obtained that the printer always has only the emulation program necessary for the printing job actually executed.

4) When the power of the printer is turned on, the printer server selects one of a plurality of emulation programs held by the printer server, which is predicted to be used, supplies the selected emulation program to the printer, and further performs a client operation via a network. Prior to execution of a print job requested by the server, a program matching the print job is selected from the emulation programs provided to the printer and executed.

By adopting this mode, the printer device always has an effect that it has a minimum emulation program necessary for the printing job actually executed.
