.. my scanner on the HP Officejet Pro 8600 N911g will not connect the scanner program to my iMAC??

If that 'scanner program' was provided by HP, then contact them for assistance with it. That will probably be a waste of time though.

HP Officejet Pro 8600 Plus e-All-in-One Inkjet Printer. The HP Officejet Pro 8600 Plus is a multi-functional inkjet printer on steroids.

Fortunately you don't need that program because the ability to use a scanner is already incorporated in macOS, and has been for a long time. Open the Preview app, and select File > Import from(the name of your scanner).

Refer to Mac Basics: Using a scanner which describes all the options.

Can I bypass Mojave and use Mountain LIon OS, that was working great with scanning on this printer??

Yes. If you have a backup (Time Machine or the equivalent) of that system you can restore it. Read Restore your Mac from a backup and follow the instructions under Restore all your files.
