Spool32 Errors

I have a computer that keeps getting a spool32 error. I have deleted and replaced the spool32.exe several times. I have done everything that Microsoft suggest. It seems to work for a couple of days and then it gets the error again. It is printing toa HP Laserjet 2050. I have removed the driver and reinstalled it. I have no clue on what to do next, short of reimaging it.

Any suggestions?

Thanks.
Russell
