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 &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 proportional spacing at-
tributes: the first byte, m0, 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 max-
imum limits:
Character mode
ml m0 + ml i- m2

Next comes the dot data. Normal character height 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 vertical dots, with the MSB being the top
dot and the LSB the bottom dot.
