I'm using the v15 API to render images. My screen display is great, but when the output device is a printer, all I get is black.

What do I need to do to get a grayscale output like L_PrintBitmap?

Here's one possible cause: if the screen is full color (24
or 32 bit) and the printer is Black and White, this type of problem could occur if your code does not contain correct palette handling.

Palette handling is shown in the code sample at the end of the L_PaintDC help topic.
