Using Pjl; Overview Of How Commands Are Used - HP Color LaserJet 5500 Technical Reference Manual

Using PJL

Introduction
Overview of How
Commands are
Used
This chapter describes how PJL commands are used. After
reading this chapter, you can create basic jobs and perform
simple PJL tasks, such as printer language switching and
changing some PJL feature settings.
To give you an understanding of where to look for more PJL
information, this chapter explains how the manual
categorizes PJL commands into six groups of related
commands. Each command has a brief description of its
function to help familiarize you with the PJL language.
Note
Each PJL printer supports a different set of PJL
commands. See Appendix A for printer-specific information.
As previously explained, PJL resides "above" other printer
languages such as PCL and PostScript. PJL commands
encapsulate the printer language jobs, as shown in
Figure 3-1. The Universal Exit Language (UEL) command
allows the printer to alternate between interpreting PJL
commands and printer language commands. (Although PCL
and PostScript are shown in Figure 3-1, other printer
languages can be involved.)
