Print Resolution
The Print Resolution setting defines the number of dots printed per
inch (dpi). Usually, the higher the setting, the sharper the clarity of
printed characters and graphics. Higher settings may require more
printer memory and increase the time it takes to print a document.
Not all of the print quality settings are valid for all resolutions.
1200 Image Quality
If you select 1200 Image Quality, the printer varies the size of each
printed pixel, thereby producing a continuous tone effect. This
improves the print quality of graphic fills and images and half-
tones.
1200 Image Quality may require additional printer memory and
may slow print time.
If your printer driver does not provide 1200 Image Quality under
the Print Resolution menu, select 600 dpi and select 1200 Image
Quality under the Options or Features menus.
If Toner Saver is On, the setting for 1200 Image Quality is ignored.
When printing 1200 Image Quality, the printer ignores the settings
for PQET.
Print Darkness
Use the Print Darkness setting to darken or lighten all printed ele-

printing requirements, particularly for basic text printing. If you
want finer line width, higher definition graphics, or a wider range
