Device Attendance
Commands
Introduction
PJL enables you to change messages displayed on the printer control
panel. This capability is useful for alerting operators to perform
specific actions, such as loading paper or pressing keys. This chapter
describes the following three device attendance commands:
RDYMSG specifies a “ready message” that replaces the “00
READY” message on the printer control panel. The RDYMSG
command does not affect the online state.
OPMSG displays a specified “operator message” on the
printer control panel and takes the printer offline.
STMSG displays the specified “status message” on the printer
control panel and takes the printer offline. It returns the name
of the key that the operator pressed to put the printer back
online.
Note Some PJL printers do not support the device attendance commands.
See Appendix A for a list of features supported by each printer.
Note For information about products newer than those included in this
book, see the Printer Job Language Technical Reference Addendum,
which includes product-specific information about newer products, as
well as commands and variables added to PJL to support these
newer products.
