3-54 PJL 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.
