All,
When I print out PDFs with very light colors on my b/w LaserJet the
light colors come out as a spotty gray. I understand why that happens. My
solution is to write a plugin that will 'darken' the pdf before sending it
to the LaserJet. That was accomplished in a windows2000 environment. Now,
there are other people in my organization that want the plug-in that are
running win95/98. The function I use to darken the PDF is
SetColorAdjustment(windows GDI) which is only compatible with win2000/NT/XP.
Does anyone have another solution I could take that would make it compatible
for win98? At print time I have the DC and ASStrm that is going to be
printed, I just don't know how to modify the colors other than
SetColorAdjustment.

Thanks in advance,

-jb
