The postscript1.0-files are beeing printed by a Laser4L-CUPS-queue
on FS-1020D wonderfully. But using the duplex-ppd-file from
Kyocera (see URL three postings above). I can also print the
postscript1.0-files on e.g. canoni550, epsonStyus600, Kyocera-FS600, ...
but the problem is, that the special ppd-file for Kyocera FS 1020D
doesn't cope with postscript1.0.
BTW: any other "modern" postscript3.0 files from e.g. OpenOffice,
     Netscape, ... are printed duplex with Kyocera-1020D wonderfully.

I don't think that it's a problem of postscript interpreter. FS-1020D
is *NO* postscript printer but PCL5-printer!
(BTW: what's a "PostScript Interpreter"?)

ideas?
