Answer 1

Done! Through Twain interface

Python 3.8.2

Install the twain module from https://www.lfd.uci.edu/~gohlke/pythonlibs/#twainmodule

Python code:

import twain

sm = twain.SourceManager(0)
ss = sm.OpenSource("Epson Perfection V19")

ss.RequestAcquire(0,0)
rv = ss.XferImageNatively()
if rv:
    (handle, count) = rv
    twain.DIBToBMFile(handle, 'scan_01.bmp')
