Command Reference
GS S – Return Printer Status
Description
Returns a single status byte, from which the printer status is determined by testing the
individual bits within this returned status byte. Only bits that have defined values should
be tested – do not test bits designated as reserved.
When polling for the status byte, your program must wait for the status byte to arrive.
The printer will take several milliseconds to process the request and then transmit the
status byte. If your program does not wait for a received character, you may receive
erroneous results.
