4.2 CONTROLLING THE PRINTER
4.2.1
Self test
You can check how your LaserPrinter 4111 is printing and have a look at its
parameter settings by sending this Self Test command:
<ESC>
Z
Notice that the z is lowercase; this is the only PCL command that ends with
a small letter. After you send a Self Test command, the printer finishes
printing any pages left in its memory. Then on a new page it prints its current
parameters (just important items such as number of copies and fonts in use).
The printer finishes off the page with a continuous display of all the
characters in its default font.
The printer also quickly checks its interface. Assuming it finds no trouble,
the printer is then ready for your next page. If the printer detects a problem
it shows a control panel message, which you can look up h your Star
La.~erPrinter4111Operations Manual.
