Clears the 24-dot download characters and defines one or more new 48-dot
characters and stores them in RAM for later use. DIP switch 2 must be set to OFF;
otherwise RAM is used as an input buffer, not downloading characters, and this
command is ignored.
rzl +n2 x 256
indicates how many bytes that will follow with this command.
rz3
is the character code of the first character defined and
n4 is
the character code
of the last character defined. n-?must be equal to or less than
n4.
The data for each character start with three bytes specifying proportional spacing
attributes: the first byte,
mO,
specifies the left of the character; the second byte,
ml,
specifies the character width; the third byte, specifies the right of the character.
These values must not exceed the following maximum limits:
Character mode
ml
mO+ml +m2
Pica 31 36
Elite
27 30
Semi-condensed 19
24
Proportional 37 42
Super/Subscript
19 36
Prop. super/subscript 37
42
Next comes the dot data. Normal character height is 48 dots, so there must be 6
x
ml
bytes of dot data. If the printer is in super/subscript mode, however, the
character height is 32 dots, so there must be 4 x
ml
bytes of dot data.
Each data byte indicates eight vertical dots, with the most significant bit being the
top dot, and the least significant bit being the bottom dot.
For further details, please refer to chapter 7.
