MoveTo(100,10);DrawTo(300,300); seems simple enough... but it isn't enough to make a line which will still be there after you minimize then restore the window. This tells you how to create persistent graphics, and talks briefly of loading bitmaps.

This tutorial shows you how to send text to a printer a line at a time. There are no complex concepts, but the need isn't universal, and the help is minimal.
