It's a result of the lack of coordination and calibration between the
different aspects of the display and printing process, including your
monitor's physical size, display resolution, application, ghostscript,
and printer.

I don't know if this will help any, but you could try HP's DJ6xx driver,
available from http://hpinkjet.sourceforge.net.  However, since it involves
patching and recompiling ghostscript, I don't know how easy it will be to
integrate it with CUPS.

Actually, ptal-hp is just one part of the hpoj package.

For that you'll probably want to look into some sort of vector graphics
program such as xfig or KIllustrator, and I'm sure there's a GNOME
equivalent to the latter.  IMO raster graphics programs like GIMP may be
more likely to get you into trouble with scaling.

Mind you, I'm not really into graphic arts myself, so my advice in that area
may not be all that helpful.
