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.
