Bug#627542: foo2zjs: Duplex printing option gone

[Till Kamppeter <till.kamppeter@gmail.com>]

Sam, does your printer have a duplex unit? Or was the duplex option in 
the PPD files only for activating a manual duplex function?

In the latter case the manual duplex function in the driver was replaced 
by a GUI tool (gnome-manual-duplex) which helps the user to get through 
the steps and to turn over the printer pages correctly.

gnome-manual-duplex is not packaged yet. It needs to be investigated how 
well it works, whether it supports only local printing or also printing 
through the network, does not have any security issues, ... and if all 
is OK it should be packaged.

Re-introducing manual duplex by a patch to the PPD file perhaps will not 
work as the code for manual duplex can be removed from the driver.
