That would be an HP 8100DN Laser printer ... but I'm not sure of the
resolution (contract is over, anyway).

Alas, we didn't have Photoshop. My "DTP" package was Word, and the
screen capture utility was SnagIt. The graphic editor was Paint Shop
Pro
6.x or Graphic Converter on the Mac (my iMac, at home). Guess I
should've mentioned that ...! Sorry about that ....

Generally, I would have to rescale the graphic for size to fit with the
rest of the text (pesky Information Mapping format ...). I might have a
setting in SnagIt that would let me do that automatically, though ...

Well, not right now (no Photoshop, and the contract is complete), but I
will certainly keep this message in my list of useful advice for a time
when it
*will* come in handy.
Thank you!
