This is not true in all cases.  You only need ghostscript-cups if
printing to a non-PostScript printer and you need to process the
input via the pstoraster/pdftoraster filter.

If you have a PostScript printer then other than pstops, the
job is just send unmodified.

If you are using a particular filter, then yes, a dependency is
required.  For this reason, the ijsgutenprint program Depends
on ghostscript.  Perhaps we should consider that CUPS filters
(such as cups-driver-gutenprint) should depend on the needed
optional filters for their correct functioning?  The same
applies to hplip and other CUPS filters.  This would ensure that
the standard dependency mechanism ensures the needed parts
are installed if required.

In summary, cups is not the place for the dependency, rather
we should probably move to mandating driver/filter packages
update their dependencies to fully specify what they need
to function.
