APPENDIX
APPENDIX 3. IDENTIFICATION OF SEND STATUS
Because the status sent from the printer has certain fixed bits, it is possible to
identify to which command the status belongs.
When using ASB (Automatic Status Back), however, the first byte of ASB should be
checked, and then the three consecutive bytes except for XOFF should be treated as
ASB data.
