Understanding the situation is worth a lot. Thanks for explaining that scanner and printer have their own drivers and are seen separately. Maybe I just need to let this problem rest for a while and use the Lenovo for scan and print. I’m so good at this that now I can’t even print! The driver search that takes place during “ADD PRINTER” actually does find three of them for my exact model of printer, but one is obviously not appropriate (I forget why) and the other two have both been tried without success. I also manged to “create” a printer with the URI copied from the Lenovo, but it wouldn’t print or scan either. And I really don’t know if that is “the driver” or if they are somewhere else. So then I copied the one from the Lenovo, but that didn’t fix the problem either. However it still didn’t work, and that hpcups file was less than half the size of the one on the Lenovo, obviously not the same. I got it installed using apt to install printer-driver-hpcups. usr/lib/cups/filter/hpcups from the Lenovo to the HP box, because at one point in trying to install drivers the HP box complained that the above file was missing, and it was. I think they are different but I’m not sure how to make them the same. Why would one box work and the other one NOT?Īny ideas out there? (Yes, I can just scan to the one that works… ) The error message is “FAILED TO SCAN, unable to start scan” However, at the same time the scanner does come to life and I can hear it mechanically scanning, but the printer display screen hangs at “Scanning to computer” so the printer receives the request to initiate a scan, but when it tries to send the data to the computer the computer won’t accept it. On the HP desktop, when the same scanner app scans for devices, it comes up with only ONE choice, and it’s the one that starts with “ESCL HP…” – and it doesn’t work. The device that has been chosen is “Hewlett Pac …” and it works. The only difference I can see between the two is that when the Lenovo scan app looks for scanners, it comes up with TWO choices: one that starts with “ESCL HP…” and the other starts with “Hewlett Pac …”. HPLIP is not installed on either box, having been removed on both because it didn’t help. The scan app is “Document Scanner” (comes with Zorin). A common ethernet network connects the three devices. The other one (HP EliteDesk) can print, but cannot scan. (Ubuntu 20.04) One of them (Lenovo) can print to and scan from my HP LaserJet Pro MFP M130fn. To remove the QR Code scanner and generator, simply run command: flatpak uninstall have 2 desktop computers both with recent installations of Zorin-16. Once installed, open it from system application launcher and enjoy! Uninstall Decoder: Then open terminal and install the scanner: flatpak install flathub.First follow the guide to setup flatpak if you’re first time installing an flatpak application.The software project is hosted in Gnome Gitlab.īesides building from the source code, it so far only offers the universal Linux flatpak package which can be installed via following steps: There’s also an icon to capture from a screenshot. The software supports for scanning from computer webcam via “Scan” tab. It offers export button to export codes to PNG or SVG image files, and save button to make the code available in History tab. The generated QR Codes can be either in white or dark. It can generates QR codes for either text or Wifi Network to share with your friends. Looking for a QR Code scanning and generating application for Linux? Here’s an open-source GTK+ tool called ‘Decoder’ which offers a modern user interface.ĭecoder is a free and open-source tool designed for Gnome Desktop.
