GS a n selects a status for ASB transmission. ASB is enabled if any status item is selected. The printer
automatically transmits a 4-byte status message whenever the status changes. Multiple status items
can be selected. When n=0, ASB is disabled. The default (n=0 or 2) depends on DIP switch 2-1
settings. If ASB is enabled when the printer is disabled by ESC = , the printer transmits a 4-byte
status message whenever the status changes. The status items are selected using n as follows:
