Can't use network printer via samba, how to debug the problem?

  • 772

I've got a network printer available through samba and I'd like to use it from my Ubuntu 14.04. Unfortunately simply adding it through Printers is not enough. If I try to use it it says: Connection failed: NT_STATUS_UNSUCCESSFUL and then Unable to connect to CIFS host, will retry in 60 seconds...

How can I debug these things and learn the reason it doesn't work?

  1. Maybe it will be helpful for someone.

    I encountered the same problem on Ubuntu 14.04. Steps below solved it for me:

    • remove printer added via System Settings->Printers
    • open localhost:631 in the browser
    • go to Administration tab, click Add Printer button and follow the instructions

    I don't know why, but only after adding printer in such way it works for me and for my colleagues.

  2. I solved this by modifying the printer Device URI to include the username and password, in the format:

    smb://username:[email protected]/printer

    (to change this, go to System settings > Printers, then right-click on the printer icon)
