Spooler problems reinstalling Lexmark

I had Lexmark all-in-one X5260 and an old Epson printer installed on my Vista
Business Sony Vaio laptop without problem since early 2008. Yesterday I
removed the old Epson, with problems, as it had a test print still in the
spooler. Since then I have had ???Spooler SubSystem App??? problems and been
unable to re-install or print from the Lexmark. I did System Restore back to
the day before I removed the Epson printer. I carefully removed the Epson
printer. Still no printing with Lexmark. I have followed the
recommendations of many of the posts here, especially ???Spooler SubSystem App???
with Alan Morris and Eddie. I uninstalled Lexmark. I followed the procedure
recommended in http://members.shaw.ca/bsanders/CleanPrinterDrivers.htm
and presumed I deleted the drivers and spoolers. However I was unable to do
the ???net stop spooler??? and ???net stop spooler???. I got the response ???System
error 5 has occurred. Access is denied???. In Command Prompt I was not at the
root directory, I was at C:\Users\Vaio. (Vaio is my user name.) I am the
only user of this laptop and my printer is plugged into a USB port, not
networked.
I then tried to install from the Lexmark 5200 Series CD. Before getting to
the ???detecting your printer??? phase, I got the Spooler SubSystem App closed
error message. Lexmark 5200 now appears in my printers but a test page print
or doc print does not work.
