For example, to redefine the character map for the 35th character and replace it
with internal master character 346, the “Redefine Character Set” command is
used as follows:
[ESC] [ S <3> <0> <35> <90> <1>
^^^^ ^^ ^^^^^^
| | +- 346
th
Character in the Master set
| | [(1*256) + 90]
| +------- 35
th
Character
+----------- 3
Bytes to follow [(0*256) + 3]
The new map will remain until the printer is power cycled or the character set
is redefined. The code page and character set commands completely redefine
the table.
