Windows 2003 print queue

I am having to restart my print spooler in windows 2003 server quite a few times throughtout the day in order for a couple of printers to continue spooling jobs and finally print them. The error i’m getting at the server console is:
“The print spooler was unable to connect to your printer….”

From the actual printer spooler I get:
“Spooling – Unable To Connect”

Any clues or fixit’s will be greatly appreciated.
I’ve check Ms Website, google..etc to no avail.

Thanks in advance
