Why didn't the guy who created this just use the font metrics? I mean,
you've got the font so you know the metrics. And the metrics have more
resolution than 1/4*X and 1/8*Y.

PrtGraph/VRPrint doesn't appear to have any font interfacing other than
the ability to choose a font from the list of those available. Maybe
there's a Rexx library somewhere that can do this, although I tend to
just use the default Courier font. I don't remember too much about how
OS/2 fonts work; I think PrtGraph/VRPrint will use the system soft fonts
rather than the printer's hard fonts which I use when writing PCL.

Basically I just need to squeeze a variety of reports onto sheets of
paper. Most of this stuff is OS/2 Radio studio tracking and I'm tired
of setting the margins differently for every report. I'd rather just
send the reports through a little program that determines the widest
line and then sets the margins accordingly. When the lines are "too
wide" I just kern the letters closer together. I suppose PostScript
would be easier but I never learned it.

Thanks for your help on this.
