Introduction to Dot Graphics

The dot graphics mode allows your Apex80 to produce pictures, graphs, charts, or almost any other pictorial material you can devise. Because many commercial software programs use graphics, you may be able to print pictures and graphs like the ones on this page and the next by simply giving your software a few instructions.

The quickest and easiest way to print graphics on your Apex80 is to use a commercial graphics program. With such programs you usually create an image on your monitor and then give a command to send the image to the printer.
