Print server takes a longgg time to spool documents

Ok here's my situation.  We have a Windows 2003 Print Server sharing 133 printers with approx. 300 users.  We have 4 Terminal Servers hosting about half of all of our users, which all connect to printers on the print server.  We're experiencing extremly slow spooling on some printers on some larger documents (larger meaning 50MB).  Other printers receiving print jobs from the thin clients via the Terminal Servers, get stuck in que.  We end up having to restart the print spooler, printer or deleting the job.  We have recently upgraded our memory (to 4gb) but with no success. The CPU's do not max out at the time of the problems.  There are no unusual errors in the event log.   Our C drive has 28GB of free space.
I had set up the server to reboot and auto-login weekly thinking that might help, which it has minimally.  We're still experiencing problems with this and I'm all out of ideas.  I wouldn't mark this as urgent, but the CEO's new secretary was trying to print a page from a .pdf and it took extremely long.  She made sure everyone knew about it.
Thanks in advance!

OK, a couple things you can look at....:
1)  Is your antivirus checking every document prior to it being spooled?  This can have a drastic impact on performance.
2)  You should clear your pagefile when you shutdown to keep it refreshed
3)  What is the physical memory on you printers? i.e. you will have trouble if a 50 MB document is sent to a printer w/ 32 MB onboard.
4)  You can dedicate an entire processor (assuming you have dual) to the spool service using the processor affinity in Server 2003, that would definitely yield results
5)  You can give precedence to the CEO's secretary so her documents are given a higher priority...

Let me know if any of these look like avenues for you.  Before I did anything, I would look at number 1) and number 3) though.

Good Luck,
