Define 48-dot download characters

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.

rz3is 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.
