146 Universal Control Commands
MAPPING CHARACTERS
The commands in this subsection enable you to map a printable character
to each data byte value between 0 and 255, to select a character from
ROM (permanent memory), or to download and select a character from
RAM (temporary memory).
Mapping a character to a data byte value re-assigns the action the printer
takes when it receives a data byte with that value.
For example, if you map the letter "A" to data byte value 33, normally
associated with the exclamation mark, "!", then each time the printer
receives that data byte value, an "A" is printed.
Note:
Remapping characters does not affect their use in control
commands.
Current settings for all data byte values are stored in the data byte map.
The data byte map is a group of five maps in printer memory that describe
the action the printer performs when it receives a data byte. These maps
are described below:
Data Byte Action Map
Describes whether each data byte
value between 0 and 255 is
interpreted as a control code or a
printable character.
Control Code Map
Describes the control codes currently
assigned to data byte values between
0 and 255.
