That'd be fine with me.

Yes, I agree (and that's what I wanted to have anyway ;) I just wanted to
make sure we have a reasonable accuracy builtin.

Hm ... of course that wouldn't work for GDI/PCL printers.

Just looked at it
(http://www.adobe.com/products/printerdrivers/systemreqs.html)
System Requirements:
. A printer that includes AdobeR PostScriptR Level 2 or PostScript 3T
. A PostScript Printer Description (PPD) file for your printer
Yuck! So you need both a Postscript printer as well as a PPD _before_ you
can use it. Not exactly likely to be present in some Windows installation.
