I recently discovered that if I have a printer attached to a Windows
machine (and shared via samba), it'll unusable on default install, because
samba-client isn't installed by default.
control-center's printers panel managed to discover the printer, but after
the driver prompt dialog it gave a cryptic error message and did not
install the printer.
After installing samba-client, adding a samba network printer worked as
expected. Therefor I suggest we add samba-client to our default
installation, it's only 1.2MB.
Ideally I think it should be added as a Requires in control-center's spec
file, but we could add it to comps instead. If you think adding this to the
default install is a bad idea, control-center should install it with
packagekit whenever users tries to add a Samba printer.
On a related (printing) note, I think it would also make sense to have
hpijs as a default as well, to support more printers.
