Introduction to Dot Graphics
Welcome to the world of Epson graphics. To get you off to a solid
start, we use this chapter to discuss all the fundamentals of dot
graphics, from the number of dots per page to the way to position one
dot, before we show you several patterns that you can print by using
one dot at a time.
Dots and Matrixes
Imagine the blank printout page as a huge canvas that is made up
of a series of dot matrixes. You can use this page like an artist’s canvas
to create your own graphic images. Where the painter uses brush
and paint, you will use the computer and printer to express your
artistic ideas.
Think of the page as a series of matrixes. For an FX-80 page and Pica
characters, for example, you can calculate the number of main col-
umns across a page by multiplying:
80 matrixes wide
X
6 columns per matrix
=
480 dots per row
Then you can calculate the numbers of rows down a page by multi-
plying:
66 lines per page
X
12 dots high per line
=
792 dots per column
