Unfortunately you made only the first step and not all.
Looking at
https://openprinting.org/driver/hplip/
will lead you via "Supported Devices"-link to
https://developers.hp.com/hp-linux-imaging-and-printing/supported_devices/index
At HP's website you'll search and find the information that it is Full supported.
HP LaserJet 400 MFP m425dn
Min HPLIP Version: 3.12.6
Chrome OS Support: Yes
Driver Plug-in: Yes
Supported Level: Full
Print Model: Mono
Scan PC: Yes
So, install the required hplip packages for Debian (OpenSource) and see that it is supported.
Thank you, Klaus! I was disappointed I didn't find it because I remember having to modify some CUPS driver or interface many years ago when I first got the printer. And that was to print. I'm not sure I ever got reliable scanning on Linux.
I'll report back soon.
I got stuck with incompatible package requirements for network use, so I filed a bug report. Their support is active (last release was this year), so I'm hoping for a fix.
In the meantime, I do have the two alternatives: (1) scan to USB drive or (2) use my Windows box. Since I'm unhooking my KVM switch setup to make my wife happy (she's a neat freak and I'm not), I'll have to manually unplug KVM cables from the Debian box to hook up them up to the Windows box, so laziness and the desire for weening from Windows will probably dictate option 1.
