when in P–Series protocol. Y
ou can print text and graphics on the same line
only
by using the
Bit
Image protocol in Serial Matrix protocol. In either mode, printing text is the default mode. Conse

each line of graphics data must include the necessary plot mode commands to enable the print

Serial Matrix Compatible Bit Image Graphics

The
printer produces Bit Image graphics in Serial Matrix
protocol. Bit Image graphics are created by
printing
a series of vertical Bit Image data bytes which represent the binary code bit pattern. This meth
-
od
utilizes the “1” or “true” bit from a binary data byte to print dot patterns. These data bytes are actu
-
ally the binary equivalent of ASCII character decimal values 0 through 255. When the data byte is
rotated
vertically
, the result is a vertical data byte pattern with the Most Significant Bit (MSB) at the
top.

Plotting a Bit Image Pattern

A
Bit Image pattern is produced by following these steps:
1. Lay out the graphic(s) pattern on a quadrille pad or graph paper.
2. Determine the decimal equivalent of each Bit Image data byte required to produce the pattern
(Figure 4–1).
3. Write a program to generate the complete pattern.
4. Enter and run the program on the host computer.
