Defines one or more new characters and stores them in RAM for
later use. DIP switch 2-l must be OFF; otherwise RAM is used as
an input buffer, not for downloading characters, and this command
is ignored.
nl is the character code of the first character defined and n2 is the
character code of the last character defined. nl and n2 must both be
between 33 and 254. nl must be equal to or less than n2. Use of
character codes 32 (space) and 127 (delete code) should be avoided
if possible. The data for each character start with three bytes
specifying propottional spacing attributes: the first byte, m0, speci-
fies 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:

Next comes the dot data. Normalcharacterheight is 24 dots, so there
must be 3 x ml bytes of dot data. If the printer is in super/subscript
mode, however, the character height is 16 dots, so there must be 2
x ml bytes of dot data.
Each data byte indicates eight verical dots, with the MSB being the
top dot and the LSB the bottom dot.
For further details, please refer to chapter 5.
