Embodiment 1
[0019] Embodiment 1: Dot matrix design of Russian letters, dot matrix ASCII coding and mapping construction with Russian ASCII original code.
[0020] The specific implementation process according to the present invention is as follows:
[0021] Do a dot matrix design for 66 Russian letters one by one. First, set an 8×14 blank dot matrix for the design of a certain Russian alphabet. In the first 10 columns of the dot matrix, mark "dots" at the corresponding positions according to the Russian letter form, so that the figure composed of this series of "dots" has the basic shape corresponding to the Russian letters, and the remaining positions are "empty"; The 4 columns are used to control the interval between Russian characters, all of which are "empty". Complete the dot matrix design of all Russian letters in the same way, figure 2 It is represented by 66 Russian letters in dot matrix form.
[0022] ASCII encoding of Russian alphabet dot matrix. Take the letter "Б" as an example ...
Embodiment 2
[0032] Example 2: Printout of domestic stylus printer with Russian characters
[0033] (1) Implementation preparation:
[0034] (1) A laptop computer is used as the upper computer, and a domestic OKI dot matrix printer is connected, and the upper computer is connected to the dot matrix printer through the parallel port.
[0035] (2) The Russian original codes of Russian characters and their dot matrix ASCII code mapping relationships are pre-stored in the host computer. This embodiment will use Russian characters "—", "space", "|", "(" And ")", corresponding to the original Russian ASCII codes "D4", "20", "B3", "28" and "29". According to steps ① to ③ of the present invention, the dot matrix ASCII codes are respectively designed as "0010001000100010001000000000 ", "0000000000000000000000000000", "0000000000FF0000000000000000", "0000000040800000000000000000" and "0000000024438000000000000000".
[0036] (3) A segment of the binary data stream collected by the printout port of the test ...
