The only printer/scanner company that I know of that explicitly supports
Linux is HP. HPLIP already comes installed on Slackware, and, while is
can be a bit tricky at times to set up, it HPLIP does work well. Check
the device list here:

https://developers.hp.com/hp-linux-imaging-and-printing/supported_devices/index

The list contains several Scanjet models that work with HPLIP.

Keep on eye on the "Driver Plug-in" column: these are proprietary binary
blobs needed for full functionality.  These can be a bit trick to
install sometimes.

Or opt for one if the multifunction printers: buy a scanner and get a
printer for free!

My corporate overlord provided for my home office a HP LJ M1212nf MFP
that has worked well since Slackware 14.1.  Slackware-14.2 has
HPLIP-3.16.5 but its not hard to compile 3.20.6 (Slackware-current) if
the printer/scanner needs the newer version.
