Automatic Status Back

Enable/disable Automatic Status Back (ASB)

ASCII: GS a n
Hexadecimal: 1D 61 n
Decimal:
29 97 n
Range of n: 0 - 255
Default:
0 (ASB disabled)
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 input 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 contents.
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
The bits of n are defined in the table.
