rpc server is unavailable & Print spooler service is not running

I took my computer (Dell Demension 2400) over to a friends yesterday
and her took out a bunch of programs that he said I didn't need to help
my computer run faster. When I hooked up everything today including my
Lexmark X75 printer I got a wizard which stated: Prolem installing
Lexmart All in One, error occurred during installation, the RPC Server
is unavailable. I went to try and re-install Lexmark and got a prompt
saying that is "Could not be completed, Print Spooler Serive is not
running. I tried removing it from programs and re-installing but same
think keeps happening. My friend is unavailable at this time and I
need to use my printer. I also had my old HP hooked up and both worked
fine until yesterday when I disconnected everything to take to his
house and he worked on it. Any help would be appreciated. Thanks!
