Compress Printing Mode

You can compress your printing data to the ratio of 75% by following the steps below.
Note:
Compress printing mode is effective only when the printer is in the ESC/P (PLQ-20/PLQ-20M) or ESC/P2 (PLQ-20D/PLQ-20DM) mode.
Turn off the printer.
Caution:
Whenever you turn off the printer, wait at least five seconds before turning it back on; otherwise you may damage the printer.
Turn on the printer while holding the F1/Eject and Offline buttons. The printer makes two short beeps and enters the compress printing mode.
