Designing a Bit Image Pattern
A bit image pattern is produced in four steps:
1. On a quadrille pad or graph paper, lay out the graphic pattern you want to
print. (See Figure 5.)
2. Determine the decimal equivalent of each vertical data byte in your
pattern. (The sum of the decimal equivalent of each true bit in the vertical
data byte is the decimal equivalent of the data byte.)
3. Write a program to generate the pattern.
4. Enter and run the program on the host computer.

Bit Image Density
You can print bit image graphics in different dot densities. Select dot densities
by sending a control code in the data stream.
NOTE: Every line of graphics data must include the necessary bit image
command so the printer can perform the chosen graphics functions.
Single Density Mode: ESC K
Single density mode selects normal density bit image graphics of 60 dpi
horizontally and 72 dpi vertically.
