Comment 7 for bug 1760593

Ok, copying models.dat from the desktop (which worked) to the laptop (which didn't work) made scanning possible. It resolved my problem (but not this issue).

Question remains, why the models.dat on my laptop was not the latest? Now, I do not recall how I installed hplip, but both my desktop and laptop have version 3.16.3+repack0-1 installed. I installed it months ago and lived with the scanning problem, and unfortunately, time erased my memory.

I believe that I downloaded hplip from https://developers.hp.com/hp-linux-imaging-and-printing/gethplip, pretty sure for the desktop, not sure for the laptop. But since the versions are the same on both machines, it looks like I installed hplip from the same downloaded package. It would fit my normal behavior.

If models.dat is already installed and a new version of hplip gets installed, is models.dat replaced? I expect so, but I must ask.

Any hope to figure out what went wrong?

Final note; curiously, when I only copied manually the section of models.dat that are related to my MFP to the old version of models.dat, it did not work. It only worked when I copied the whole file to the laptop. Thank you for your help.
