If %20 is used in place of space in the password, adding works. Possibly extends to all special characters, but haven't tested that extensively. STEPS TO REPRODUCE 1. Add printer, selecting Samba/Windows URI 2. Fill in uri, user and password 3. Select printer driver OBSERVED RESULT Printer is not added if password contains a space. EXPECTED RESULT Printer should be added and password encoded/encrypted properly even if password contains space or other special characters.

Using the CUPS Web-Interface, however, did work with the %20 workaround. 2487804 3 noeerover 2026-01-23 18:10:30 +0000 Git commit b919691a7003b5b449a55c1a6000c827dace4efa by Mike Noe.
