HP PCL/PJL reference - Printer Job Language Technical Reference Manual

EN Status Readback Commands 7-29

USTATUS Category

The INFO USTATUS command lists each type of unsolicited status

supported by the printer, such as DEVICE, JOB, PAGE, and TIMED

(see the “USTATUS Command” discussion on the next page for

information about unsolicited status). The listing also contains the

current setting and the possible values for each type of status. For

more information concerning the different types of unsolicited status,

see the “USTATUS Command” section later in this chapter.

Example: Using the INFO USTATUS Command

This example requests information about the unsolicited status

variables. These are variables that can be used in the USTATUS

command. In this example, the HP LaserJet 4 printer replies that

there are 4 unsolicited status types: DEVICE, JOB, PAGE, and

TIMED. The current setting for each type of unsolicited status is

given, along with the possible variable values (for instance, OFF, ON,

and VERBOSE for device status).
