Printing graphics
The OKIDATA 120's graphics capabilities let your print
charts, graphs and pictures. The easiest way to create
graphics is by using a graphics software package. With
these packages, you usually create an image on your
screen and then instruct your computer to send the image
to your printer. Like a newspaper photograph, these images
are composed of thousands of tiny dots
.
Your software
package tells the OKIDATA 120 where to print each dot.
More advanced programmers might want to try writing pro-
grams that produce graphic images. This takes time, pa-
tience, and an understanding of how your printer functions
.
