Abstract

PURPOSE:To execute the performance of a data transfer time and to efficiently execute the processing by holding and dynamically switching printer control information at a terminal side to hold a printer. CONSTITUTION:The terminal to hold a shared printer 5 is composed of a register 6 to hold the terminal number of a printing output requesting source, a register 7 to hold printer control information and a memory table 8 to store the control information corresponding to the terminal number of the requesting source. When the printing request is made from a certain terminal, the data are outputted at the time of the same as the terminal number of the register 6, as they are. When the number is different, the register 6 is updated, the register 7 is updated by the contents of the memory table 8, the control information of the register 7 is also outputted to the printer 5 and the control information of the printer 5 is rewritten. Thus, each time the terminal of the requesting source is requested, it is not necessary to set the control information of the printer to a row unit and a page unit, and therefore, the efficiency of the processing and the performance improvement of the data transfer time can be executed.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a shared printer control method suitable for controlling control information of the shared printer in a system in which one printer is shared by a plurality of terminals. It is related to.

[Conventional technology]

In the conventional system, as described in Japanese Patent Application Laid-Open No. 58-29043, information from a request source is always passed page by page.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, printer control information is added from the requester page by page, but conversely, it must be added even if it is not necessary, resulting in overhead of data transfer time and re-setup of the printer. loss time was not taken into account.

An object of the present invention is to, in a shared printer control system, not receive printer control information from a requesting terminal;
This information is held on the terminal that holds the printer,
The purpose is to switch dynamically.

[Means to solve the problem]

The above purpose is in a terminal that holds a shared printer.

A register that holds printer control information and variable tables for the number of terminals that share the shared printer are maintained in memory, and the latest printer control information sent from each requesting terminal is stored in these tables. Store in.

Control of the shared printer can be achieved by resetting the control information in the printer table to the printer when the terminal number of the printer output request changes.

〔Example〕

An embodiment of the present invention will be described below.

FIG. 1 shows a system consisting of a terminal controller (TCE) 1 and terminals 2, 3.4 connected thereunder. The terminals 2 and 3 make a print request to the shared printer 5 connected to the terminal 4.

Next, FIG. 2 shows a block diagram of the terminal 4 that holds the shared printer 5, including a register 6 that holds the terminal number of the print output request source, and a register 7 that holds the printer control information.
, and a memory table 8 that stores control information corresponding to the terminal number of the request source.

When a print request comes from a certain terminal, if it is the same as the terminal number in the register 6, the data is output as is. If it is different, update register 6 and update register 7.
and the control information of the terminal in memory table 8, and if they do not match.

The register 7 is updated with the contents of the memory table 8, and the control information of the register 7 is also output to the printer, making it possible to rewrite the printer control information.

〔Effect of the invention〕

According to the present invention, a requesting terminal that makes a print request to a shared printer does not need to set printer control information on a line-by-line or page-by-page basis each time it makes a print request, which improves processing efficiency and reduces data transfer time. Performance can be improved.

Claims (1)

[Claims] 1. In a system where one printer is shared by multiple terminals, the terminal that holds the printer has a register that stores printer control information and a table that stores control information from the requesting terminal in memory, and A shared printer control method characterized by controlling the printer while dynamically switching the printer.
