Similar problem with a similar printer...

HP Laserjet 2200dt. Worked fine with CUPS in RedHat9.
Updated to Fedora Core 2 (also tried 1 and 3 with the same results),
and printer will print only one sided. CUPS version
cups-1.1.20-11.11. Problem both when printing from applications
(acroread, gv, mozilla,...) or from command line (lpr). Does
not matter the file type (ps, pdf, text,...). Made sure
Duplex is allowed in the driver options and explored both short and long
edge tumble...

Tried default Postscript driver Fedora printer setup provides
as well as all other available drivers shown there. No change.
Tried other similar drivers from HP family (2100, 4, 4000, 5Si,...).
No result.

Printer allways prints single sided.

If of use results of lpoptions -l -d hp for this printer

Have not saved RH9 setup that have worked in the past as
in that case default driver worked just fine and I didn't suspect
any problems with upgrade.

Any ideas?

Thanks,
