Length is designated in 1 byte:
STX Printer ID Length
02H xxH xxH xxH
Length is designated in 2 bytes:
STX Printer ID
02H xxH xxH 00H
• Printer ID ......... 2-byte hex data (in order from High to Low)
• Length ............. Hex data indicating the number of bytes of command data
• When the length is designated in 1 byte: 1 byte
• When the length is designated in 2 bytes: 3 bytes
• CRC ................ 2-byte hex data (in order from Low to High)
* Between the start and the termination of storing the form, a packet including several commands
can be sent. However, the command data should not be included in two packets. For other
commands, one packet should include only one command.
