Identification Of Send Status - Citizen PPU-700 Command Reference Manual

4.3 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.
