It is a service that loads a printing job into memory as an image if it isn't an image already, instead of text, so the printer doesn't have to understand fonts or decipher graphics, the solution on windows XP is to go to the notifications area, right click on the icon that looks like a printer, and click exit, that will clear the live cache that can be over 200mb for a 3 page document, I had a 200 page document in queue, it kept my windows XP with 3gb RAM at a halt until I exited the print job, however, don't try to end it by closing "spoolsv" from tskmgr, as it will cause a critical system failure, with a one minute warning until the computer reboots.

if you have an HP printer, this file is needed so you will be able to print. if you kill or delete, you cant print
  ss  
It depends on your printer. Turn printer off, turn it on ONLY when you wanna use it. And the problem is gone
  Jackob  
A printer spooling system that sometimes takes a strange amount of CPU and memory. If you don't printing anything, I suggest ending the process. However deleting the file itself can be extremely dangerous.
  Grandmaster Quy  
it is system friendly file if no one mess with it and required to print the document in background, no need to worry.

Follow RMANN's direction. It was not a virus for me, WinXP. But it was 99% cpu.
  Bart  
It is the printer spooler service, but there is a deadly rootkit virus that takes its place once run, and since the system re-starts this process automatically, it's a pain to get rid of the virus. But the original file is legit.
   
spoolsv.exe file is running without printing. As well as it takes 50% memory
