Comments:
If C is the total number of characters to be defined,
B = (C x 13) + 2
n1 = B MOD 256
1-2 = INT(B /
256)
n3
=
20 in
all cases
n4 = the code of the first character to be defined
n5
= 0 if the top eight pins are to be used;
n5
=
128
for the bottom
eight
n6 = 0 in all cases
n7 through nk are the data numbers that define the characters, with
11 data numbers for each character.
The data numbers for each character are determined as shown on
the grid below:
Determining data numbers
To print a user-defined character, you must use ESCape I, which is
