CHAPTER 2 "PCL" - 13
3.2.3. Display functions mode
You can choose to make the printer print escape sequences instead of executing them. Send the printer the
following sequence:
EscY (27)(89) <1B><59>
Now the printer prints out escape sequences and prints the characters of the control codes. It does not execute
them. The only exceptions to this are CR, the carriage return code, which causes a carriage return and line feed to
be performed, and the EscZ escape sequence which turns the mode off.
To turn the display functions mode off and enable escape sequences to be executed again send:
EscZ (27)(90) <1B><5A>
The printer exits the display function mode after printing a character of code 1B Hex and the letter "Z". All
subsequent escape sequences and control codes are executed normally and not printed literally.
