Character Sets and Code Pages

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>
^^^^ ^^ ^^^^^^
| | +- 346th Character in the Master set
| | [(1*256) + 90]
| +------- 35th 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.
