Word 97/Win NT 4 Printer error

Hello, I was hoping someone could help with this. I have a compaq deskpro EN SFF P500 with Windows NT 4.0 SP 6a installed and another with SP 4 installed. Both of them have Office 97 Standard SR2 installed. When I try to print out to a networked Laserjet 4000tn or 4050tn I sometime's get blank pages. I can print to a LaserJet 6p that is shared on another coputer. I have tried changing the driver from the PS to the PCL driver without any luck... Any idea? Thanks in advance...
