XP prints at startup

I have a system on the network that prints at startup. It's not just a couple of pages, it prints documents from the past few months. I did a search and didn't find anything. Can anyone help?

It is printing to a laserjet 1200 with a printserver.

 

When you bring up the printer spool files for this computer, are their any documents in the queue? If documents showing and you do not need them, delete them out of the queue. If this cures the problems, but new documents cause the same problem at a later date. Look in "printserver" device options / HP software / XP software on computer. You would be looking for option to managed spool files at a "later time or date ".
