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>
^^^^ ^^ ^^^^^^
| | +-
| |
| +-------
+----------- 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.
Character font image download
[ESC] = <n1> <n2> <start code> <data>
1BH 3DH <n1> <n2> <start code> <data>
<27> <61> <n1> <n2> <start code> <data>
none
none
This command allows custom characters to be downloaded. The total count is
[(number of characters x 9) + 1] = (n1 + 256 * n2). The start code is the
starting character where the download is to start.
