Description The [GS] r <n> command transmits the status specified by <n> as follows: paper
sensor status as one byte of data when <n> = 1 or 49, and drawer kick-out
connector status when <n> = 2 or 50. The paper present status of bits 2 and 3
for the paper sensor status is not transmitted because the printer goes off line
when a paper out is detected by the paper out sensor. The paper roll low sensor
is an option. If the sensor is not installed, bits 0 and 1 for the paper sensor status
are always in the ―Paper adequate‖ status.
