Remove background colour while printing signed forms

Hi,

I have to print multiple forms which are signed digitally by two parties. While giving print command the preview is diplayed with green colour in background 

even though the green background is not shown while reading the document.

Due to this, additional ink is being consumed althought the document is printed from B&W printer.

Is there anyway to remove the background colour and keep it white to save ink.

Regards
