Okay, I believe I solved the problem. I think what happened was Windows was doing an update and muffed up the file in the process. The reason I say that:

1) My computer doesn't have a dllcache
2) There was no spoolsv.exe in Windows\system32

When did a search on it, I did find copies of it in a folder that ended with i386, and in 2 separate windows dowload folders. I grabbed the one from the latest download and copied it into the system32 directory, ran the print spooler, and voila! my fultifunction printer is now printing again (and scanning).

Thanks for the help Cambyses.
