CCITT Group 4 lossless compression
That's very good indeed. I scan text pages in B+W at slightly less resolution
(engineering prints I do higher, they need it), but compressed they turn out
to be ~50KB per page, or less - for long documents (e.g. the DOS-11 System
Programmer's Manual), that produces a reasonably-sized file.
The software I have been using i[s] Irfanview.
That's what I use too; it has tons of useful features, including being able
to drive my single-sided page-feed scanner and being able to number the
even-sided pages correctly. The one I use for this is the 'batch mode'; I can
do the entire document into CCITT 4 in one operation.
For scanning software, I highly recommend VueScan:
https://www.hamrick.com/
There are Linux, Windows and Mac versions, and it supports thousands of
scanner models, including some very old ones. VueScan can also do CCITT G4
compression, and directly create PDF files. If you but the pro version,
updates are free. I've been using it for years.
