Spooler and Server Prop Not Working

My printer worked for 5 months on XP, but now it doesn't.
All the printers in Printers and Faxes disappeared, and
the Add a Printer wizard fails. I've done my homework on
the archives, Cori Bright's site, and Bruce Sanderson's
site. But I'm still hitting a wall:

I can go to Services and make sure the print spooler and
RPC toggles are set to automatic and are running. But
when I try to use a wizard, the spooler stops. So, using
Mr. Sanderson's advice to clean old drivers and start
over by clicking on File | Server Properties, I get the
error message "Server properties cannot be viewed. Print
Spooler is not running." I went into the registry and
cleaned out the 2 and 3 subkeys exactly as he instructed,
but still no-go. Ideas?

Thanks.
