Description The [GS] a <n> command 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 enabled or
disabled. When <n> = 0, ASB is disabled.
The default depends on the offline mode configuration. If offline buffer full only is
set the ASB is defaulted on. When the printer is disabled by the [ESC] =
command and ASB is enabled, the printer transmits a 4-byte status message
every time the status changes. The paper roll low sensor is an option. If the
printer is not equipped with the paper low sensor, bits 0 and 1 of the third byte
are always on, with paper adequate status. Bit 3 of the second byte is always,
“No error.” The status items are selected using <n> as follows:
