8. DEVICE ATTENDANCE COMMANDS
8.1. Introduction
You can change display messages on the printer control panel by using PJL. The Operator can be alerted by
this feature to what specific actions should be taken. This chapter shows you three device attendance
commands.
RDYMSG
By using this command, you can change the message "00 READY" on the printer control panel into
whatever message you like. This command does not change the printer's online/offline state.
OPMSG
By using this command, the printer can display a message you specify on the printer switch panel LCD and
set the printer to off-line ( non-ready state for printing ).
STMSG
By using this command, the printer can display a message you specify on the printer control panel LCD and
the printer will go off-line. After the operator puts the printer back on-line by the on-line / off-line key, the
printer name is returned by the printer to the application.

With the RDYMSG command, you can change the message "00 READY" on the printer control panel into a
