The printer protocol was changed from LPD (Line Printer Daemon) to IPP (Internet Printing Protocol). The CUPS driver was not selected (the default setting is Generic PostScript Printer). The computer was unable to connect to the printer so it selected the iPF5000 as default.
Printer Export Plug-in: The current CS3 export module will function normally under versions of Vista with the latest printer drivers installed. (applies only to iPF5000 , 8000, 9000, 8000s, 9000s, 6100, 8100, 9100, W6400PG, and W8400PG)
