DEVICE ATTENDANCE COMMANDS 

8.1. 

Introduction 

You can change dis play 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.
