PhotoGrade is available on the LaserWriter IIf and IIg, but must be
enabled by setting the Color/Grayscale radio button in the "Print"
dialog.
Also, PhotoGrade requires quite a bit of memory to print large, high
quality images. Increase the RAM in the IIf and IIg.
Use the LaserWriter Utility that ships on a disk with the IIf and
IIg to adjust the PhotoGrade settings for more levels of gray, or
higher resolution.
Finally, some applications don't automatically use Photograde, and
must be set to do so. When possible, set the default to "Use
printer's settings," to allow the IIg to set the line screen and use
Photograde. If the line screen must be set manually, set it to 106
lpi (the default for the IIg).
