Print servers

I have 20 print servers set up on w2000, workstations are on NT4 sp6.
when printing it reads on the printer properties box : “spooling….” about a good minute even on 1 page excel sheet.
Win2000 server specs: PIII 1 GHZ, 20 GB HD, 640 MB Ram.
Ihad the same setup on NT4 server , print speed is faster.
Pls advise
