Print Spooler on the Business Objects Server

Is it neccessary to have a Print Spooler service running on a Business Objects server? Our server is going down (rebooting itself) lately. a typical message from our event logs just before the crashes:

Printer Driver HP LaserJet 8100 Series PCL6 for Windows NT x86 Version-3 was added or updated. Files:- UNIDRV.DLL, UNIDRVUI.DLL, HPLJ81P6.GPD, UNIDRV.HLP, hpmopyui.ini, hpoemui.dll, PCL5ERES.DLL, PCLXL.DLL, PCLXL.GPD, P6FONT.GPD, PJL.GPD, P6DISP.GPD, TTFSUB.GPD, UNIRES.DLL, STDNAMES.GPD.

Thanks,
