Status Readback Commands - Lexmark 33S0300 - Mono Chrome Laser Printer Reference

Status Readback Commands

Applications can request configuration and status information from the printer using
the Status Readback commands. In addition, the printer can also be instructed to send
unsolicited status information back to the host computer when asynchronous events
occur, such as a memory error or a paper jam.
To determine which commands your printer supports, see "Table B-8: Status
Readback Commands" on page B-14.
