Introduction to Dot Graphics
The Epson dot graphics mode allows your LX-80 printer to produce pictures, graphs, charts, or almost any other illustrative or creative material you can devise. Instead of using the standard letters, numerals, and symbols stored in the LX-80’s ROM (Read Only Memory), the graphics mode prints dots column by column and line by line. You plan where you want the dots to appear and then use a program to tell the LX-80 where to put them.
Because many software programs take advantage of Epson dot graphics, you may be able to print graphics like the ones on this page and the next by simply giving your software a few instructions. The chart on the next page, for example, was created and printed in about 10 minutes.
