Trouble Printing Color Images in B&W

I have a VB.NET application running on Windows 2000 Pro. I have a DeskJet
5550 printer, with the Windows default setup specifying to print in
grayscale.

From a 3rd-Party DLL called QuickPDF, I specified monochrome and print the
document. It ignores the monochrome flag and prints in color, so I figured
QuickPDF needs to go back to the drawing board.

But then I tried transferring the document into a MemoryStream and printing
it using a PrintDocument object, after setting color = false using the
PrinterSettings, DefaultPrinterSettings, and PageSettings objects. It still
prints in color!

Is there something non-standard about the industry-standard Hewlet Packard
deskjet printers, whereby the internal command for specifying black and
white printing gets ignored / overridden?

What might be the cause / solution? Thanks.
