I have written a program to capture signal from machine and display it on screen in the form of sinosoidal wave. I have print buffer for 256 X 400 pixel strip chart. This prints fine if I set page size A4 and resolution 600 DPI. If anyone changes print parameters , there is problem. I can resize the printer buffer and interpolate the stored signal.

My problem is , how to find the printer resolution from GetDeviceCaps ? how to know the Print Type Normal / Draft etc in mFC.

Pl tell me any link if it is there ..

Thanking you ..
