Yes, this is right. Both it works with hplip-3.21.2. This page is one of the google targets when searching why 3.18.4 not working (doesn't allow to scan with Laserjet MFP-M28 failing after "Warming up..." when "Scanning..."). Maybe please keep for other people (if they use similar environment like I do, but I think that for Ubuntu this info could be useful too in someway). For rhel I used these commands to reinstall 3.21.2 above default 3.18.4: 1. Download from HP 3.21.2: https://developers.hp.com/hp-linux-imaging-and-printing/gethplip 2. Reinstall default version: sudo dnf reinstall hplip hplip-common hplip-gui hplip-libs libsane-hpaio 3. Install 3.21.2 above default version with dependency check skipping (since non possible to remove default one): sudo rpm --nodeps --force --install ~/install/hplip-3.21.2-RHEL8-x86_64.rpm 4. Fix python to be both /usr/bin/python and 3.6 one (that is default one for my system): sudo ln /usr/bin/python3.6 /usr/bin/python 5. Download required hp-plugins for 3.21.2: sudo hp-plugin 6. Now scanning works Ok: hp-scan -g -r200 -- 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 HP LaserJet Pro MFP M28a fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/hplip/+bug/1811504/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
