I have the exact same problem on Ubuntu 3.18.04 with hplip 3.19.12 installed. It worked fine for a few months but things went wrong a few days ago (scanner now only works in gray mode and up to 200 dpi). So maybe an update caused a regression ?
I updated to hplip 3.20.3 and 3.20.3 plugin but to no avail. I also tried the solution described in #61 but it didn't help (simple scan simply freezes completely). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1811504 Title: scan with Laserjet MFP-M28 fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1811504/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
