Defines new characters and stores them in RAM for later use. EDS
switch A-3 must be OFF; otherwise RAM is used as an input buffer,
not downloading characters, and this command is ignored.
Downlosding characters in IBM mode requires Dot Pattern data and
Character Index Table data. Dot Pattern data controls which pins fire
when printing a character. Index Table data is placed in a “lookup
table” that provides information on where Dot Pattern data is stored
in memory an defines certain attributes of the character.
(n1 + n2
x
256) gives the number of bytes to be downloaded.
n3 and n4 indicate the low order and high order addresses in which
data is to be stored. n3 should be 15 and n4 should be 128 for this
printer.
n5 determines the character mode to be downloaded, as shown below:

m1 through m9 indicate Index Table data.
m1 and m2 indicate the address where Dot Pattern is stored. m1 is the
high-order byte. m3 indicates the number of columns in the character
memory, and m4 indicates the number of columns in the character.
m5 through m9 are compression mask bits. Data compression allows
the efficient use of memory in storing downloaded characters, providing
space for more characters than would be available without compression.
The printer repeats the previous dot column in the current column
when the current column compression mask bit is set to 1.
