[AccessD] Access Report - Colored Page Heading - Printing Problem

All,

This is really a strange one.

We have an Access 2007 application that prints a one-page document.  For
internal purposes, the users wanted the header at the top of page to be
printed with a blue background.  This has worked fine for the past two
months.

Now, for some strange reason, the printer is losing the setting to print
in color and reverts back to printing in black.

Temporarily, the users are opening up the printer properties and
selecting "color" each time they print.

I am really puzzled why this problem started to happen after two months
of color printing.

Is there some way to programmatically (from Access) change the printer
setting to "color".  This would eliminate the need for our users to do
so manually.

Thanks,
Brad
