If you want to detect if your printer is capable of printing graphics, large bitmaps, and DIBs, then you can check it by the next procedure:


begin
if (GetDeviceCaps(Printer.Canvas.Handle, RASTERCAPS) and RC_NONE) =
RC_NONE then
<graphic is not capable>;

if (GetDeviceCaps(Printer.Canvas.Handle, RASTERCAPS) and RC_STRETCHDIB) =
RC_STRETCHDIB then
<printer supports the StretchDIB>
else
<Windows will simulate the StretchDIB>;
end;
