Greeting.
I'm sure this is way outside the scope of BL questions but I'm not sure where else to go.

In BL 4.5 I somehow got XSANE without doing anything on purpose about it, so I don't know if it was part of the BL disk or came with HPLIP. When I installed BL 5.0 I installed CUPS and then ran apt install --reinstall hplip and then hp-setup -i (before, I ran the HPLIP download that I had gotten from HP). I just accepted all the defaults and the printer works fine. There was no XSANE so I installed it (apt install xsane) and it sort of works but I only get the first inch or so of a 8.5x11 scan.

I couldn't find any parameters in the XSANE menus that did anything. Any chance anyone knows how to make this work?

Which model HP device are you using? Does using 'hp-scan' result in a proper scan?

What is reported by the following?

@ferrari,
Thanks for responding. I have an HP Desk Jet 2132.
I don't know what "hp-scan" is. Is that something I have simply by virtue of hplip? How do I use/invoke it?

I'll check out the result of the command sequence you posted, but it's really hot in the office now so I'm going to wait until it cools off

Thanks again.

Yes, it's part of HPLIP. Run it from a terminal.

Thanks. I'll check it out.

@ferrari,

Indeed, hp-scan results in a proper scan. I need to study the parameters to use it better but that's great. Thanks.

As for
export SANE_DEBUG_DLL=128
scanimage -L

there's too much output to post here. What am I looking for specifically?

That is the HPLIP scanning utility that will use the hpaio backend automatically.

Not really needed now that we know that the scanner driver is working. However, in general you can upload lengthy output to https://pastebin.com/ and post the link that it provides here.

I'm wondering if the wrong SANE backend was being used here. Check for uncommented scanner backends in /etc/sane.d/dll.conf
