m selects a bar code system as follows: [Description for Њ ] • d indicates the character code to be printed and k indicates the number of characters to be printed. [Description for Ќ ] • n indicates the number of bar code data, and the printer processes n bytes from the next character data as bar code data. • d indicates the character code to be printed.
