Hi, there was a bug regarding color printing in 2.4.1, which is mostly fixed (only one corner case remains to fix) in the current master branch of CUPS. Relevant PRs: https://github.com/OpenPrinting/cups/pull/417 https://github.com/OpenPrinting/cups/pull/451 https://github.com/OpenPrinting/cups/pull/500 You can ask your distro maintainer for including those patches until there is a new release.
