Appendix III - Transmission Status Identification

Because the specified status bits transmitted from the ESC/POS commands are

fixed, the user can 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 r and the status of the second and following bytes

of the ASB cannot be differentiated.
