Some people have that some colored papers fade when used in a LaserWriter.
Before committing to any type of paper, consider the manual's advice. Page
129 of the LaserWriter IINTX manual carries the following specifications
for printing paper-based materials:
"16-lb. to 20-lb. photocopy or typewriter bond (60 to 80 g/m^2) in normal
mode; up to 36-lb. (135 g/m^2) stock in manual mode with face-up tray open.
Accepts most letterhead and colored stock."
Any paper that meets the above specifications and is designed for
photocopier use should work properly and show no discoloration. The best
method for determining if colored paper will discolor is to test it.
Note: The fuser generates temperatures between 165 and 180 degrees
centigrade.
