PATCH: _a2ps printers

[Peter Stephenson <pws@xxxxxxx>]

a2ps understands system printers in addition to the ones specifically
configured into it.  I suspect most of us with pre-packaged a2ps's are
relying on the former.

It didn't seem worth using _alternative or anything more complicated,
feel free to change.
