HPLIP

scan issue

Asked by Stephen Camidge

I am a Linux newbie, running Manjaro. I have installed HPLIP 3.21.4 and although I can print, I cannot scan. Please advise.

My printer is HP Color LaserJet Pro MFP M180nw

I was able to previously earlier this year using Skanlite or Document Scanner, but not directly with HPLIP

Then the latest revision updated the software and now I cannot connect to the scanner.

Wireless? USB? Wireless would be less work.

Does Manjaro (Arch Linux based?) provide a sane-airscan package?

Manjaro does provide a sane-airscan package (it is not installed).

The HP is connected by usb and printing works,

Does Manjaro provide an ipp-usb package? If so, install it and
give

  lsusb -v | grep -A 3 bInterfaceClass.*7

  systemctl list-units "ipp-usb*" | grep service

after re-plugging the device into USB.

(Wireless would be less work :) ).

With 'lsusb -v | less' you are looking for "bInterfaceProtocol 4". You
have an AirPrint device; it would be unusual not to have it in the
output (with or without ipp-us).

I do not have a program called bInterfaceProtocol 4, nor is it available in the repository

That wasn't the quey!

Execute

  lsusb -v | less

and search or look for bInterfaceProtocol 4 in its output.

It would be good if you gave the complete output of

  lsusb -v

I got it. I don't recall how exactly, but I went to Actions then was prompted to install sane then it found the printer and enabled scan. I hope if it gets lost again that I will be able to recreate where I go to...

Thank you very much for your help.
