Changing the Print Mode
Use the front-panel Print Mode key to toggle between
the three print quality settings.
Any software driver will override the front-panel setting
(but it will not change the LED). Use your driver for
setting the print quality of images sent from your
computer. Use the front-panel to set the print quality for
internal prints.
HP 5000 Only
If your software raster imaging processor (RIP) system
has print quality settings, select your print mode from
the RIP. It will override the front-panel settings.
See Print Speeds and Print Mode Selection for more
information about appropriate combinations of paper
type and print modes.
NOTE: You cannot change the print mode setting for
pages being received or already in the printer's internal
queue.
