A Russian character printout method for test equipment

Abstract

The invention discloses a method for printing out Russian characters of a testing device. First, all Russian characters are designed in a dot matrix display form in an off-line state, and the designed dot matrix is ​​ASCII coded, and the dot matrix ASCII code is Establish a one-to-one mapping relationship with the Russian-made ASCII original code of Russian characters and store it in the host computer in advance, and then send the print binary data stream obtained from the print port of the test device to the host computer in an online state to print a line The character data stream is used as the unit to convert the code stream of the printing instruction and the printing content, convert the original code stream into a new code stream, and finally send the converted code stream to the domestic dot matrix printer to drive it to compress at multiple densities mode to print out dot-matrix graphics. Without any modification to the standard printing character code table and instructions of the domestic dot matrix printer, the Russian printing effect with the same character form and specifications as the original Russian-made printing device can be realized.

Description

Technical field [0001] The invention belongs to the technical field of printing, and relates to a Russian character printing output method of a test device, and specifically, to a Russian character printing output method of a test device based on a dot matrix design and multiple density compression. Background technique [0002] Test equipment is necessary equipment for the weapon system to make technical preparations and ensure that it is in good condition. At present, the original factory imported test equipment is used to conduct technical preparation tests on the equipment condition. The test results are printed out, which is also the only output method of the test equipment, and the test results must be printed by a dedicated Russian-made printing device, which cannot be replaced by domestic printing equipment. Since the technical content of the test equipment has not been disclosed to me, once the printing device fails, it can only be returned to the original Russian facto...

AI Technical Summary

Problems solved by technology

However, in the actual operation process, it was found that although the domestic dot matrix printer can correctly execute the translated printing instructions, it cannot print out the test content correctly. The reason is that the test results are displayed in Russian, and the special Russian characters in the Russian-made printing device and There are inconsistencies in the mapping relationship and character specifications of the standard Russian characters of domestic dot matrix printers, resulting in printing abnormalities such as garbled characters and uneven text formats, and this problem cannot be solved by ordinary measures such as full-width / half-width switching
