European users should add the /isolatin1 to the parameter list of device.
This simplifies the use of national characters.

A couple of plotters will be quite happy with this procedure. However, some
devices with cut paper may show a problem: The printable area is smaller
than the paper size: We have 6 special purpose PS printers, all support A4,
some printers support a couple of other paper sizes as well. I checked
the PPDs of some ouf our printers and found it a horrible task to process
a PPD with IDL.
A long time ago there was a procedure called phaser.pro (which now resides
in the obsolete directory) that handles the printable area of some Tektronix
Phaser printers... A more modern procedure should be able to read the PPD
of the printer and find out the imageable area. The user may then shrink the
imageable area to suit his purposes.
Maybe I've overlooked it: How does ps_form center the printable area?
... just a couple of thoughts
