I'm unable to find a driver for a Canon imageCLASS MF244dw on Ubuntu 16.04 LTS. I found a rather old ppa for this but it doesn't appear to work I get the following after adding it as a repository and running apt-get:
W: The repository 'https://launchpad.net/~michael-gruz/+archive/ubuntu/canon xenial Release' does not have a Release file. N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use. N: See apt-secure(8) manpage for repository creation and user configuration details. E: Failed to fetch https://launchpad.net/~michael-gruz/+archive/ubuntu/canon/dists/xenial/main/binary-amd64/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead.
Also, I don't really see the printer on the list. If I share the printer via a machine that has the drivers (a Windows machine) over Samba would it still be possible to print?
