APPENDIX E: TRANSMISSION STATUS IDENTIFICATION
The values of specific bits are fixed in the status information transmitted by the printer, so that the
status bytes of commands can be identified. The user can therefore confirm the command to which
the status belongs, as shown in the following table.
When using Auto Status Back (ASB), however, process the consecutive three-byte code
(except for XOFF) as ASB data after confirming the first byte of the ASB. Otherwise, the
status transmitted by using the GS I and the status of the second and following bytes of the
ASB cannot be differentiated.
