ESC & m n1 n2 [d] k
[Function] Define user characters
[Code] <1B>H<26>H<m><n1><n2>[<d>]k
[Range] {m = 0, 1, 2, 3(Hex)}
{20 =< n1 =< FF(Hex)}
{n1 =< n2 =< FF(Hex)}
{k=(n2-n1+1)*48} (m=2)
{k=(n2-n1+1)*16} (m=3)
[Outline] Defines a group of user characters.
m=0: Copy internal character set A to user character set A
(Parameters n1, n2 and d are omitted)
m=1: Copy internal character set B to user character set B
(Parameters n1, n2 and d are omitted)
m=2: For Font A (12 × 24), n1 denotes Start character code and n2 End character
code. Every character is 48 bytes, two bytes for each line. Only the first nibble
of the second byte is used.
m=3: Define character group with ASCII codes between >= n1 and =< n2 for character
set B (9 × 16). Every character is 16 bytes.
[Caution] The data for character set A is composed from left to right and from top to bottom
with two bytes for each horizontal line. The first byte contains the first 8 bits with
the left most bit is MSB. From the second byte only the first nibble (the most significant
4 bits) is valid.
The data for character set B is composed from left to right and from top to bottom
with only one byte for each horizontal line. The nineth bith is alawys 0.
Downloaded characters are valid even after switching off the printer or after issuing
Initialize command.
