CHAPTER 5 PJL - 51 

The printer status to be sent to the host computer are ;  

• 

Device status changes - printer cover open, paper jams, paper out, etc 

• 

Job status changes - completion of the printing of a job, receiving a 

JOB

 command 

• 

Page status changes - ejecting a printed page  

All the unsolicited status information (USTATUS DEVICE, JOB, PAGE and TIMED) is turned off at once by 
the USTATUSOFF command.  Each status can be turned off individually by the corresponding USTATUS 
command.  

The USTATUS TIMED command specifies after which time period the printer sends the unsolicited status 
information and is turned off by setting the time increment to zero with this command. 

To get information about the current settings or possible settings for unsolicited status, use the INFO 
USTATUS command.

7.6.1.  Device variable 

The 

@PJL USTATUS DEVICE

 command allows the printer to send status messages when the printer status 

changes.  The printer will send the status by the status code shown in the table below. 

Status code 

Status 

10000 - 10999

Status information such as printer on-line or off-line. 

11000 - 11999 

Status of available paper in paper input sources, such as paper empty and auto-
switching to another paper source.   

20000 - 20999 

PJL parser errors.  The entire command line of a PJL command is ignored when an 
error (except for code 20004 ) occurs. 

25000 - 25999 

PJL parser errors.  Part of a PJL command is ignored when the error occurs. 

27000 - 27999 

PJL semantic errors, which means that they are grammatically acceptable but 
cannot be executed.  For example,  attempting to lock the only unlocked paper 
tray causes this error.  

30000 - 30999 

Errors which do not stop the printing procedure if the CONTINUE is set to AUTO 
(auto continue mode).  If the CONTINUE mode is set to STOP, the printer stops 
printing and goes to off-line status and only resumes when the CONTINUE or 
SEL key are pressed.
