Scanning App

Courtesy of an ill informed Supervisor, I am now stuck with a Dell all in one piece of junk running Win11.
Even in God mode it won't let me install the software and drivers for my ancient Lexmark printer/scanner.
Does anyone know of a portable Scanning app?
Hate to toss working hardware just because some Hipster twit thinks I should only use "Shiney, Shiney, New" hardware.
