Apple LaserWriter 12/640 PS - Manual (Page 74)

6 Choose the output tray from the pop-up menu.
Face Down output tray is the default. This tray is located on the top of the
printer and stacks the output media face down.
The Face Up output reduces the curl of your paper by using a “straight-
through” paper path through the printer. This is useful when you print on
heavy media, such as transparencies, envelopes, and postcards.
Note: You can use Face Up output with or without the optional face-up
output tray. However, the face-up output tray stacks the papers neatly in
a tray instead of on the surface where the printer is located.
7 Click Send to send the paper-handling settings to the printer.
Selecting imaging options
FinePrint provides smoother, less jagged printing of text characters. You can
set the printer’s default setting for the FinePrint feature to on or off. Users can
change this setting from the Print Options dialog box. To print high-quality
images with PhotoGrade, turn off FinePrint.
PhotoGrade enhances the look of printed images, such as scanned
photographs, by providing more shades of gray and better printed clarity and
contrast. If your LaserWriter 12/640 PS has been upgraded to a minimum of
12 MB of memory, you can use PhotoGrade. You can set the printer’s default
to have PhotoGrade turned on and off.
