This would be a function of the software, not the scanner.

When I corresponded with Al Kossow about format several years ago, he
indicated that CCITT Group 4 lossless compression was their standard.

I have been using a scanner (Ricoh IS300e) that needs a driver that
doesn't install under Windows 10, so now I use it from inside a Windows
7 VM.  The software I have been using in Irfanview.

I expect it would not be tremendously difficult to find something that
would do the compression on a raw file.
