My OS is Debian 11 and my printer is an HP LaserJet Pro MFP M28a. After the first install using the hplip package, both printing and scanning were working fine but, for some reason, I had to reinstall the printer and then the scanner became unreachable from XSane at all.

I have tried several options and I either get error message code 9 ("error: SANE: Error during device I/O") or 10 ("error: SANE: Out of memory (code=10)") when trying to launch XSane. Is it actually an error from XSane or from the whole configuration on my computer?

By the way, here is the output from hp-check:

I know there is some warning telling me Debian 11 is not supported and that some required packages are missing (and I did not remove them since then), but I did manage to make the scanner work at first, so there must be a way to get it back running (without messing too much with the packages).

  • I could not create an xsane tag so I chose to use the sane one as the closest match.

  • It's telling you that the "missing" packages are required for hplib/XSane to work.

  • @waltinator: As I said, I managed to make it work without bothering with these error messages. The dependencies are meant for Debian 10.7 and I am using Debian 11. Hence the inconsistency in the error messages. Nevertheless, I do have all packages cups 2.3.3op2-3+deb11u1, libcups 2.3.3op2-3+deb11u1, python3-pyqt5 (and not Qt4) 5.15.2+dfsg-3 and gtk2-engines-pixbuf 2.24.33-2 installed properly on my computer.

  • I've just provided a driverless workaround here but I am still interested in finding an actual way to use the HPLIP solution as well...

A possible first workaround (i.e. not using the full power of the HPLIP solution) is to use an independently developed driverless backend which is sane-airscan, as described in Section 2.2.2.2 of the Debian 11 release notes. After installing the package of the same name, I just had to use the eSCL protocol version of my scanner in the list provided at XSane opening.

scanimage -L might be a useful commandline to check whether that new special version of your scanner becomes indeed available or not after installing sane-airscan.

Try using escl:http://localhost:60001 instead of escl:http://127.0.0.1:60001 . The latter now returns a HTTP redirect to http://localhost, which the escl backend does not handle.

  • I don't know how to configure that within the HPLIP Toolbox. There, I just have access to the command launching xsane (/usr/bin/xsane -V %SANE_URI% in my case). So far, if I clic on the HPLIP Toolbox icon that launches it, I receive the following error: "Error opening peripheral 'hpaio:/usb/HP_LaserJet_MFP_M28-M31?serial=VNC3R77190': input/output error on the peripheral." (broadly translated from French)
