during adding SMB printer shared from WinXP, 'Browse' button works but 'Verify' does not

[Wladimir Mutel]

LUbuntu 18.04.1 with all updates, 32-bit x86 PC, top-level package 'lubuntu-desktop' is installed,
smbclient/smbspool are installed but smbd/nmbd are not (to save runtime RAM)

MFU Canon MF3228 is attached to Windows XP and shared from it by SMB
XP is not a domain member, only workgroup.
For 'security' reasons, a user is created on WinXP with name 'print' and password 'print1' (because guest access apparently did not work)

Now, I start 'system-config-printer' as root and try to add a printer.
I select 'Windows printer via Samba', I enter XP IP and printer share name into 'smb://' field, then click 'Browse'. After a short pause, I get 'Authorization required' dialog where I can enter login, domain/workgroup and password. And there, my Authorization is successful, I can select shared printer name and click 'OK'.

But to complete printer setup, I have to enter these login and password into 'Authentication' section, where I see 'Verify' button. Above it I also see 'Username:' and 'Password:' fields, where password is entered above the username for unknown reason, and no field for workgroup or domain.
And I was never able to Verify the same login and password fields however I tried. I entered login and password in the reverse, I prepended XP hostname and workgroup name before login, I used '\' and '/' separators - no luck

Surely I know that Linux interoperation with Windows is not of top priority with Ubuntu developers, but I would be happy if such kind of a very popular household scenario were tested for Ubuntu LTS releases in some way. Thank you in advance for your responses.
