Figure 4-2. Vertical Data Byte Pattern
If each 1" or true bit is plotted, the result is a Bit Image plot of the ASCII character A". The
relationship of ASCII character, decimal value, and Bit Image plot is shown in Figure 4-3.

Figure 4-3. Bit Image Pattern from an ASCII Character
Any byte, such as the one in the previous example, can be identified by its binary, octal, hexaĆ
decimal, or decimal equivalent and subsequently used to generate a Bit Image pattern. A table
of the standard ASCII character set and equivalences is included in Appendix A. Use this table
to quickly identify the various equivalences of ASCII characters. Bit Image plotting is not limĆ
ited to printable ASCII characters; Bit Image patterns can be plotted for any 8-bit data byte
with decimal values ranging from 0 to 255.
NOTE: Printing solid black bit image for extended periods will overheat the hammer
bank.
