Hi again,

first of all, many thanks to both Brian and Keith for discussing all
this new (for me at least) information.

Then, some clarification: as far as I am concerned, the only thing
that matters in the short term is to digitize the thousands
photographs in 10x15 cm format now piled in small boxes over, and all
around my desk as soon as possible, so they can be properly archived
somewhere else. Right now, I have barely the space to move the
mouse...

I already have a bash/zenity script (ask me offline if you want it!)
that, when I place four 10x15cm photographs side by side in a flatbed scanner:

1: calls scanimage to make one A4 scan at the highest supported resolution

2: splits the resulting image in four smaller ones, each matching very
   closely one of those photographs, and saves them, with progressive
   numbers, into a folder where I can grab and edit them later on
   
3: "GOTO 1" if I place four new photographs into the scanner and click
   on the "Continue" button by Zenity

so all I need *now* is to know which scanner to buy, and which SANE
package(s) to install on Ubuntu 22.04 to be sure that, once I have
changed the scanner name ( -d option) in the scanimage call,
everything will work exactly as above right away, without wasting
hours or days to tweak stuff. I can worry about everything else
e.g. optimizing images, OCR integration, GUIs and so on when I'm done
with the photographs, no problem.

And from your discussion I understand that if I buy a Canon Canoscan
LiDE 400, the current standard SANE package(s) of Ubuntu 22.04 will be
enough, won't they?

Thanks,
Marco
