(2)SI, SO and US, RS command
In case the 8 bit data is specified (data bit length of serial communication), the function of SI and SO codes is same as the function of US and RS. But in case 7 bit data is specified, SI, SO works for specifying of SI side (characters from 20H to 7FH) and for specifying of SO side (characters from A0H to FFH)
1Standard character specifying (SI, US) command By inputting SI (0FH) and US (1FH) codes, printer cancels the double wide characters and the data after this command is printed in standard characters. The characters can be canceled by this command is only double wide character, double wide and double high character can not be canceled.
2Double wide character specifying (SO, RS) command By inputting SO (0EH) and RS (1EH) into the nominated columns, the data after this command is printed in double wide character. This is canceled by line feed operation or inputting SI or US command. Although both of standard character and double wide character can exist in one line.
When the total characters goes to 24 (40) columns on the basis of calculation at standard character basis, printer performs automatic printing (buffer full printing)
