Defining Graphic Image Data

Graphic images are created by a series of dots printed in a

specific pattern. This pattern results from a process of turning

dots "ON" or "OFF" on the printhead.

We will use the terms "black dots" to describe a dot that is ON,

and "white dots" for a dot that is OFF.

This section describes how to build a data stream to create this

pattern with your printer.

This example shows

how black dots and

white dots form an

image of the letter A.

To create a data stream for this image, start with the bottom row.

Count the number of white dots and black dots, in order of

appearance in each row.

For example, rows 1 through 4 (at the bottom) in the image above

have these dot counts:

Row 1: 4 White, 8 Black, 19 White, 8 Black, 4 White

Row 2: 4 White, 8 Black, 19 White, 8 Black, 4 White

Row 3: 4 White, 8 Black, 19 White, 8 Black, 4 White

Row 4: 5 White, 7 Black, 19 White, 7 Black, 5 White

Row 3

Row 2

Row 1
