Status of ASB
Enables or disables automatic status back (ASB) and specifies the status items.
This command is a batch mode command; that is, it is processed after all prior
data in the receive buffer has been processed. There may be a time lag between
the printer receiving this command and changing the ASB response, depending
on the receive buffer status.
If any of the status items listed are selected, ASB is enabled and the printer
automatically transmits 4 status bytes whenever the selected status changes. If no
status is selected, ASB is disabled. All four status bytes are transmitted without
checking DSR.
If the error status is enabled, a change in the following conditions will trigger the
ASB:
♦
Cash Drawer
♦
Receipt Cover
♦
Knife Error
♦
Out-of-Range Printhead Temperature
♦
Out-of-Range Voltage
♦
Paper Exhaust Status
♦
Slip Paper
