This makes me feel bad. I can see David is making his output to fall
presicely where it needs to be. I am happy when I can see at least a
fraction of what I need somewhere in the corner of the printout. It
indicates to me that I have a hope of getting it all into a
comprehensible file for future positioning using Adobe or Canvas :-(

I have always had a strange feeling about it. IDL is not as gentle to
printers, as, lets say, Word, which will always propose "printable
margins" (which have little to do with printer capabilities, because it
puts them in even for my Lexmark inkjet that has none).

Not on my LaserJet HP 5MP. Even then, the frame from the sample code is
off by 0.2". Sorry. I could try other departmental printers but I am
afraid this will introduce more noise in the 0.25 +- 0.25" existing so far.

Not exactly, as I said above. Forget vertical positionong, that one's
off by 1".
