I'm trying to get my Ubuntu desktop to scan directly from a HP color laser jet pro MFP M477fdw all-in-one printer/scanner device. The device is on my home network.
simple-scan (the "Document Scanner" app) starts up and detects the scanner, and the "Scan" button is green. When I click the green "Scan" button, the scanner warms up and appears to be working. The scanner touchscreen says "Scanning to Computer". simple-scan then shows a white page but after half a second pops up a dialog that says "Failed to scan ... Unable to start scan" and the only option is to close that dialog.
scanimage -L detects the scanner.
$ scanimage -L
device `escl:http://10.1.1.80:8080' is a ESCL HP Color LaserJet MFP M477fdw (E0EDEB) flatbed scanner
device `hpaio:/net/hp_color_laserjet_mfp_m477fdw?ip=10.1.1.80&queue=false' is a Hewlett-Packard hp_color_laserjet_mfp_m477fdw all-in-one
Workaround: set up a samba share "network folder". The scanner can connect to over the network to save scanned images.
Printing to the device (over my network) works as expected. Ubuntu auto-detects the device as a printer and auto-configures it.
I don't want to run the hplip GUI if I don't have to. I just really don't like the blue "HP" icon in my system tray.
Software versions:
- 64-bit Ubuntu GNU/Linux Desktop, 20.04.1 LTS
- simple-scan 3.36.3
I got it working. I ran
sudo apt install hplip-guithenhp-setup. It couldn't discover the scanner so I had to enter its hostname. I chose to not add another print queue (it was already there) and not add a fax queue.simple-scan ("Document Scanner") now shows three options for scanners. One works. The one that works is named "HP HP_Color_LaserJet_MFP_M477fdw".
I think the important thing hp-setup did was to download a plugin. I had to enter my credentials so it could install the plugin. Then I just skipped printer & fax setup and closed the hp-setup GUI, then ran simple-scan.
I don't see a HP icon in my system tray even after doing this.
