Printer Configs (.pltcfg)

Im trying to set a number of default settings in my printer config (.pltcfg), one of which is printing in colour.

Currently "Default Colour Mode" is set to true colour, however this will only print the pages in colour if I select all pages -> Right Click -> Properties -> Advanced -> Color Options -> True Colour.

The printer is also setup for colour within windows.

Have I missed an obvious setting somewhere thats preventing the colour printing?
