Hi Shivani I was trying to get my HP Color LaserJet Pro MFP M177fw to work with Xsane. I have had it working in the past, but now it keeps coming up with "Failed to open device 'hpaio:/net/hp_color_laserjet_pro_mfp_m177fw?ip=192.168.43.63&queue=false'. Error during device I/O " I was trying to update to the latest version of hplip in case the problem had been fixed, however after viewing the changes between 3.20.3 and 3.20.6 there was nothing changed that was relevant, so I have stopped trying. I also discovered that HP Device Manager ver. 15.0, /usr/bin/hp-toolbox comes up with an error "error: No module named 'PyQt4'" For some unknown reason this is not a dependency, and Pyqt4 does not exist in the Kubuntu repositories. There are a number of Pyqt5 packages, so I am guessing that I need an updated version of HP Device Manager, which is not available. Might be time to upgrade to a Canon printer with sane support. In case you are interested the following is the output from /usr/bin/hp-toolbox and /usr/bin/hp-check It includes the comment that "Ubuntu-20.04 version is not supported." =========================================================================================== andrew@Alienware-17:~/Downloads/Deb$ /usr/bin/hp-toolbox HP Linux Imaging and Printing System (ver. 3.20.3) HP Device Manager ver. 15.0 Copyright (c) 2001-18 HP Development Company, LP This software comes with ABSOLUTELY NO WARRANTY.

Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies are installed to successfully compile HPLIP. 2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball has the proper dependencies installed to successfully run. 3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time dependencies). Check types: a. EXTERNALDEP - External Dependencies b. GENERALDEP - General Dependencies (required both at compile and run time) c. COMPILEDEP - Compile time Dependencies d.
