I don't think this is necessary, but to be sure, I updated kdeprint
to save correctly ImageableArea and PaperDimension in the PPD file
(both in CVS-HEAD and 3.1 branch).

In the context of KDEPrint, print margins are also meaningfull on the
client side, to produce PS, which is not the case of XPP or gtklp, that
simply passes options to the CUPS server; margins are meaningfull only
on server side. And margin values are only used when CUPS generates PS
itself (when you print text or image files), otherwise, if you feed
CUPS server with PS, I don't think those margin values are used at all.
Margin on client-side are only supported since KDE-3.1/Qt-3.1, because
Qt was missing the possibility to specify the print margins. Moreover,
with Qt < 3.1, margins were only specified with 2 values: top/bottom
and left/right. 4 values specification is new to Qt-3.1.
Margins on server-side are supported since almost the beginning. But
you can only find them when they are meaningfull, like when printing
a text file with "kprinter". That's why they are located in the "Text"
tab of the printer properties dialog.

I don't have this behavior. I downloaded the HPIJS PPD file for a
HP DJ970C, tried to print from konqueror, specified the margins as
you did above, and in both case I got correct results (note: I didn't
actually print, I just cancelled it after previewing).
