Print Data Generators - HP Color LaserJet 5500 Technical Reference Manual

Print Data
Generators
Print Data Generators are applications used to create and
print information. Examples include WordPerfect, Harvard
Graphics, and Lotus 1-2-3.
Software applications of this type should work properly
when the printer is under the direct control of the
application, and also when there is a spooler between the
application and the printer. This is accomplished by using
the ENTER command to select the proper printer language
before sending print data to the spooler or printer. The UEL
command should precede and follow the print job.
Print Data Generators should only use PJL commands
when a corresponding command does not exist in the
printer language. This is recommended so that the
application does not override feature settings and adversely
affect future jobs. To change feature settings for the
duration of the job, or until the next PJL reset condition,
use the SET command. Do not use the PJL INITIALIZE
command for Print Data Generators.
Commands Used by Print Data Generators
UEL Use before and after every PJL job.
COMMENT Use to add explanations within PJL code.
ENTER To select the correct printer language for
the print job.
SET To select a desired feature when it is not
possible using the desired printer
language (such as PCL or PostScript).
RESET Use at the end of the job if the SET
command is used in the job.
