Abstract

PURPOSE:To save the load time of a printing pattern, by checking whether the printing pattern for printing input character code is already stored in a font memory and, if not, taking out the printing pattern for the character code from an external file to store the same in the font memory. CONSTITUTION:A control means 2 refers to a code table 3 in order to check whether the printing pattern for a printing code 1 is already stored in a font memory 4. As a result, if the printing pattern corresponding to the printing code is not stored, the control means 2 reads said printing pattern from an external file 6 to store the same in the font memory 4. Thereafter, the printing order to the printing code 1 is sent to the printing means 5 of a printer and the code table 3 is updated to finalize the storing of the printing pattern for the printing code 1. When the character pattern for a character code 1 is already stored, the control means 2 immediately sends the printing code 1 to the printing means 5 of the printer. By this method, the load time of the printing pattern can be saved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer device, and particularly to a printer device in a data processing system.

[Conventional technology]

In conventional printer devices, printing patterns for all types of characters to be printed must be registered in a font memory before printing starts.

[Problem that the invention seeks to solve]

For this reason, in the conventional printer device described above, when a request is made to print a character code that is not registered in the font memory, the character code that will not be used is also registered in the font memory, resulting in a long loading time or a long loading time. The drawback is that the font memory becomes larger as the number of character codes increases.

[Failure to solve the problem]

The printer device of the present invention determines whether or not a print pattern corresponding to a print input character code has been registered in the font memory, and if it is not registered, extracts the print pattern corresponding to the character code from an external file and stores it in the font memory. It is configured with means for registering.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In the printer shown in FIG. 1, the control means 2 refers to the code table 3 in order to determine whether the print pattern for the print code 1 has been registered in the font memory 4. The code table 3 stores whether or not the print pattern has been loaded into the font memory 4 in correspondence with the character code.

As a result of referring to the code table 3, if the character pattern corresponding to the character code is not registered, the control means 2 reads the print pattern from the external file 6 and registers it in the font memory 4.

Thereafter, a print command for print code 1 is sent to the printer printing means 5, and the code table 3 is updated, so that the print pattern for print code 1 is registered.

If the character pattern for character code 1 has already been registered, control means 2 immediately sends print code 1 to printer printing means 5.

[Effects of the Invention] The printer device of the present invention registers the corresponding print pattern in the font memory only when the character is actually printed, thereby saving the size of the font memory and the time for loading the print pattern. There is an effect that it can be done.

Claims (1)

[Claims] A writable font memory, an external file that stores the print pattern for the character code, and a check to determine whether or not the print pattern for the print input character code has been registered in the font memory, and if not registered, to store the print pattern for the character code. A printer device comprising: control means for extracting a print pattern from the external file and registering it in the font memory.
