I am trying to add a Windows printer via SAMBA from the New Printer dialog in Kubuntu 12.04. The smb:// field doesn't allow me to put special character or blank spaces, except for the underscore (see screenshot). In particular, the url I am trying to add (it was given to me by IT people in my university) contains a "%20", which, I assume, should be interpreted as a space.
Is this normal? Can smb urls contain special characters? Why doesn't this dialog allow me to do that?
