Finding printer color capability in TppReport.OnEndPage

rbuser

I need to know whether the target printer is color or monochrome & I need
this in an OnEndPage handler.

I've tried this:

if GetDeviceCaps(ppReport.Printer.PrinterHandle, BITSPIXEL) > 1 then

but GetDeviceCaps always returns 0, even though PrinterHandle is non-zero.

Any ideas?

Hi Dave,

AFAIK, you have to pass a device context handle instead the printer handle.

Thanks Chris,

Any idea how I convert a printer handle into a DC handle ?

Or, is there any other way I can get the printer DC handle (which is what
the Handle property of the Delphi 'Printer' function returns) from the
ppReport object ?

Dave.

Ah, I've just discovered the DC property of TppCustomPrinter - it all
works now. Thanks for the pointer.

Dave.
