The quickest and easiest way to print graphics on your LX-90 is to

use a commercial graphics program. With such programs you usually

create an image on your monitor or TV screen and then give a com-

mand to send the image to the printer.

If you use commercial software that produces graphics, all you

need to know about dot graphics is how to use the software. The rest

of this chapter explains how the LX-90 prints graphics, demonstrates

the function with a few simple programs, and gives you a larger pro-

gram that prints any graphics created on your screen.

Dot Patterns

Graphic images are formed on the LX-90 about the same way that

pictures in newspapers and magazines are printed. If you look closely

at a newspaper photograph, you can see that it is made up of many

small dots. The LX-90 also forms its images with patterns of dots, as

many as 240 dot positions per inch horizontally and 72 dots per inch

vertically. The images you print on the LX-90 can, therefore, be as

finely detailed as the one on the first page of this chapter.

If you plan carefully where you

want the

dots to appear and then

use or create a program that gives the proper instructions to the

printer, your LX-90 will print almost any picture you can imagine.
