MicroStation Powerdraft 08.11.09.459 - Printing Issue

Today I updated all my drivers for my desktop PC - running Windows 8.1 Pro 64bit. (Drivers include BIOS, GPU, Audio, LAN, Intel etc.)

When using the print dialogue box and I select True Colour - I get my print as expected.

When I select "Monochrome" the print will take 1-2mins to be sent to the printer.

This problem exists no matter which file I try to print from, and is only an issue in Powerdraft. No other applications are addected.

Does anyone have any suggestion on a possible fix?
