SPOOLSV eating up machines RAM and hanging system

I have a client who has a laptop that on occasions it will not boot. I
checked it out earlier this week and saw under task manager that spoolsv.exe
was eating up a ton of ram (would continue to go up conitinously til it used
up all the memory). I ended the task and shut down other unnecessary services
and was able to boot. I shut down the print spooler and then went to a dos
prompt and went to c:\windows\system32\spool\printers folder and found
hundreds of thousand of paired files. I erase all these files and rebooted
and everything seemed fine.

It was fine for a couple of days and the problem has seemingly reoccured
(from what they tell me).

He does connect to his office PC via Remote Desktop Connection (pffice PC=
XP Pro) and he said he does send print jobs to the office's printers which
are then printed sucessfully.

Any ideas about what could be causing this? or what i should look for
