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 above 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:

♦

 

Receipt Cover

♦

 

Knife Error

♦

 

Out-of-Range Printhead Temperature

♦

 

Out-of-Range Voltage

♦

 

Paper Exhaust
