RE: Comparing 2 printouts (before and after) ?

[Joel Fritz <JFritz@xxxxxxxxxxxxxxxx>]

If you've saved the spool files and can sign on more than once, you can do
the same thing by flipping back and forth between the two sessions with the
spool files up on the screen.  This works even for people with my attention
span and level of attention to detail.

I like the "light table" method, though.  That's our standard for testing
form printout on plain paper.
