Printer Driver(OEMUNI): Black Output

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

i am developing a printer driver and i just want to output bitmap data
to the printer so i used the following gpd
but i just receive a black output(zeros) for that.
i just used imageprocessing function and redirected output to a file.
does my gdp file have any problems or should i do anything special?

thanks
