Foxpro halts printing to an NDPS printer

I have an application that runs on Foxpro. As soon as I installed a new printer (HP4050)with NDPS and the latest printer drivers, the Foxpro program halts when trying to print any report. Office, Notes, and all other apps print just fine to the NDPSprinter. The client is a Win95 workstation, with the Default printer set to the NDPS printer. Port is listed as \\NDPS01.
