Mac OS X Printing
Some applications do not support the printer driver Plug-in because
they provide their own printer driver. Without the Plug-in, you can select
bizhub PRO 950 specific features in the Printer Specific Options panel
of the Print dialog. Note that some features of the Plug-in, like Page
Interval or user authentication can be set only in the Plug-in, but not in
the Printer Specific Options panel due to restrictions of the PPD format.
(The PPD format does not support features with arbitrary string or
numeric values.)
