Printing mono pages as colour

[arelmedia]

Hi

I am trying to print a booklet with two colour pages and two mono pages. My printer recognises both varieties and charges me more for a colour page than a mono (black) page.

When I print direct from Indesign, the printer differentiates properly. When I create a pdf file and print from Nitro the pages are all classified as colour by the printer. It doubles my costs.

I have page alignment issues with my specific Indesign file which is why I can print the way I want from Nitro.

Is there something in the Nitro program that I can activate to get it to recognise the mono pages when it sends them to the printer?

Hoping or dreaming?
