Defines one or more new characters and stores them in RAM for
later use. EDS switch A-3 must be set OFF; otherwise RAM is
used
as an input buffer, not downloading characters, and this command is
ignored.
nl is the character code of the first character defined and /12is the
character code of the last character defined. nl must be equal to or
less than n2.
The data for each character start with three bytes specifying propor-
tional spacing attributes: the first byte, mo, specifies the left of the
character; the second byte, ml, specifies the character width; the
third byte, m2, specifies the right of the character.
These values must not exceed the following maximum limits:
Character mode
ml
mO+ ml + n/2

LQ elite
LQ semi-condensed
LQ proportional

Next comes the dot data. Normal character height is 24 dots, so there
must be 3 x m/ bytes of dot data. If the printer is in super/subscript
mode, however, the character height is 16dots, so there must be 2 x
ml bytes of dot data.
Each data byte indicateseight vertical dots, with the most significant
bit being the top dot, and the least significant bit being the bottom
dot.
