If you are a Windows or MAC user, your ASOL if you want to use an old scanner. The manufacturers don’t support updated drivers for the new operating systems. If your a linux user,you head over to http://www.sane-project.org/. So far, I am hitting 2 for 2.
I wnt here https://help.ubuntu.com/community/sane. I installed sane. I plugged in 2 old scanners. I was able to scan with both of them.
SANE is a universal scanner interface. The linux guys do some really smart things.
I use Ubuntu as one of my computer operating systems. Ubuntu makes linux easy.
(BTW They used to have a forum called the Absolute Beginners Forum. IMHO, it was the BEST computer resource forum. The best. I can’t comment on the new incarnation, new to ubuntu, mostly because the Absolute Beginners Forum was such a big help, I have not had to post a question in years.)
