Jeez, you know, when you were fiddling with that PS AT> and AT< command, I
was thinking to myself, shouldn't it be AT# a la PCL? But I figured Annie
knows her PS stuff, and I don't know diddly...

But I thought Annie said to me, in response to my question, that you *can*
have a dynamic intercharacter space command under PS? I specifically asked
her about that!

Rafe, can you parse the PS command for me, please, just to give some insight
into how PS drivers work? I.e., what are ) and (, what are s, 2, 0, and r?

Lastly, dynamic intercharacter spacing is very easy in PCL+XPL. Divide the
point size by a space constant. For example, suppose you like 1/50th of an
inch -- 6 dots -- at 12 points. So that would be 0.5 dots per one point of
measurement. Just get the current points with  into S/G 01,
then multiply by 0.5, then perform a rounding procedure, then put a PI
command -- works like a charm. Try RUNning this to turn on _dynamic_
intercharacter spacing, and hit Escape to turn it off (works like an attribute).

Did you try the HPDJ560C.PRN file? Which DeskJet do you have?
