[Bug 44459] Re: [Dapper] Can't use spaces when specifying printer name

[Kurt Pfeifle]

CUPS printer and class names may contain any printable character, except
space, tab, "/", or "#".

Also important to note: printer and class names are *not* case-
sensitive. "myprinter" and "mYpRiNtEr" are exactly the same printer for
CUPS!
