1.INTRODUCTION

1.1.About PJL

Printer Job Language(PJL) provides job status control by sending the printer status information to the application. PJL can be a valuable tool for the single-user environment, but is a much more useful tool for the networking / sharing environment.

PJL

Emulations ( BR-Script,

PCL, IBM, EPSON etc... )

Printer

PJL allows job-level control that cannot be accomplished with PCL, Postscript or other emulations. PJL includes five major features.

(1)Printer language switching

With PJL, it is possible to switch positively between the printer languages such as PCL, Postscript, Epson, IBM and Diablo directly from applications.

(2)Printer status readback

PJL can provide information such as printer model, configuration, printer feature setting, error information and other status information to the application.

(3)Front panel control

PJL can remotely control the printer's control panel settings and messages.

(4)Easy of utilization

All PJL commands except the UEL command have a user-friendly construction using printable characters and English words.

(5)Spooler control

PJL provides an improved spooler which can manage the printer better, particularly in a network environment.

Note :

The commands for Printer status readback or Front panel control can be invoked in modes other than PCL or BR-Script. However, the commands for printer status readback get the information from PCL or BR- Script and the commands for front panel control perform the settings for PCL or BR-Script.
