PCL/PJL for Beginners
This is a basic introduction to HP's PCL5e and PJL. I do not
touch on all the subjects and many of the important subjects are
missing. After reading this you should understand the format of
PCL escape sequences and PJL commands and be able to use a Hex editor to
enter these commands and control codes. There is also a section on
using macros with Canon network printers and a handy troubleshooting
section. For more information on PCL and PJL you can order the
Technical Reference Bundle from HP.
The pages start off for beginners so if you start in the middle and get
lost, back up a page or few to learn what you need. Have fun.
