I have an interesting problem that might have a simple solution:

I am using displaying color pictures on a mac ii using greyscale format.
From this position I am dumping the pictures directly to a laserwriter.

The problem: The pictures look fine on the screen, but when they output to
the laser writer there is some interference -> specifically the outlines tend
to be "whited out" in parts leaving little dots of clear space instead of a 
grey-scale pattern. I suspect it has something to do with the fact that the
laser writer can't handle such a rapid change in color/grey so quickly.

Anyone have any ideas?

Regards,
Rob
