Hello all, thanks to Thierry and Alexandre for their help. Thanks to them, I have made progresses with the scanning part of my new Epson XP-4100, but it still has some problems, and a step back too (as for my computer not working
Executive summary: - when I attached that printer to my Ubuntu 20.04 box, the printer was recognized immediately, and worked fine, the scanner not at all - today I did what Thierry and Alexandre suggested. Now scanning works with imagescan, simple-scan and at the prompt with scanimage (haven't checked quality yet), but not with skanlite. Details below. - but now... the printer part does not work anymore. I have installed the Epson driver from their website, removed and reinstalled the printer, but nothing gets printed. If I print a test page, CUPS says it was successfully printed, but nothing arrives to the printer, it does not even beep or complain. Does it have to do with updating / replacing libOT here, I guess, but any suggestion is obviously welcome. Thanks, Marco COMMANDS and their output: sudo add-apt-repository ppa:sane-project/sane-git sudo apt-get update sudo apt-get upgrade sudo apt autoremove sudo apt install libsane libsane-common sane-utils download ipp-usb from https://download.opensuse.org/repositories/home:/pzz/xUbuntu_20.04/amd64/ipp-usb_0.9.14+45.1_amd64.deb sudo dpkg -i ./ipp-usb_0.9.14+45.1_amd64.deb dpkg: regarding .../ipp-usb_0.9.14+45.1_amd64.deb containing ipp-usb: ipp-usb conflicts with ippusbxd ippusbxd (version 1.34-2ubuntu1) is present and installed. ... sudo apt remove ippusbxd sudo dpkg -i ./ipp-usb_0.9.14+45.1_amd64.deb reboot SANE_DEBUG_ESCL=255 scanimage -T 2> toto.txt (attached at the bottom!) sudo scanimage -L [sudo] password for marco: device `imagescan:esci:usb:/sys/devices/pci0000:00/0000:00:12.2/usb1/1-6/1-6:1.0' is a EPSON XP-4100_Series RESULTS of test scans with: imagescan = OK simple-scan = OK skanlite = GUI complains about I18N_EXCESS_ARGUMENTS_SUPPLIED in terminal, prints many lines like: kf5.ki18n: "1 instead of 0 arguments to message { DPI} supplied before conversion." and then ends, without scanning anything, saying: sane_read= 2 = Operation was canceled At that point, to make the printer work, I did: download linux driver from epson website sudo apt-get install lsb sudo apt --fix-broken install sudo dpkg -i aux/epson-inkjet-printer-escpr_1.7.8-1lsb3.2_amd64.deb reboot This led to having two printers in the Ubuntu settings panel, and none of them works.
