[STR New]

Duplex is not working with Collate is turned on. (Copies and Collate
worked)
lp -d Ricoh-Aficio_SP_4110N_PS -n 2 -o Duplex=DuplexNoTumble -o
Collate=True 3pages.ps

Duplex worked when Collate is off
lp -d Ricoh-Aficio_SP_4110N_PS -n 2 -o Duplex=DuplexNoTumble 3pages.ps

Printer supports hardware collate.
Tested using Postscript driver from
http://www.openprinting.org/foomatic-db/db/source/PPD/Ricoh/PS/Ricoh-Aficio_SP_4110N_PS.ppd
(There's a *OpenUI Collate section in PPD file. 
There's no cupsNumCopies line in PPD file)


Examing the Postscript file from pstops filter found that:
Collate command is happending at every page. (rather than at job level).
Collate is the only command that appears in every page.

After moves Collate command to job level, duplex and collate works.

It looks like it's a bug in pstops filter.
