Description of problem:
The setup of smb printers seems to be very counter-intuitive, and prone to 
errors.

How reproducible:
Always

Steps to Reproduce:
Use printconf from within gnome to setup an smb printer.
Wizard asks for "share"; until now, everytime I've heard "share" I thought 
to the printer share, so I typed it, wondering where I could insert the 
netbios name of the windows pc....
	

Actual Results:
Printer does not work, because for "share" the wizard wants this:
\\\\netbiosname-of-pc\\printer-name
This is the only way I could make it work after looking at 
what /usr/share/printconf/util/smbprint does.
I think noone will use the correct syntax at the first try.

Expected Results:
Wizard should have 2 fields:
Netbios name of the pc:
Netbios name of the printer share:
and use this info to build the correct syntax

Additional info:

smbprint uses -N which means "no password", but it uses the password if 
you type it. I don't know if this may cause further problems.

Maybe consider the syntax
-U$username%$password
where if variables are blank it's considered an anonymous login.
