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
Draft	9	12
LQ pica	31	36
LQ elite	27	30
LQ semi-condensed	19	24
LQ proportional	38	42
Draft super/subscript	7	12
LQ super/subscript	19	36
LQ prop. super/subscript	38	42

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 indicates eight vertical dots, with the most significant bit being the top dot, and the least significant bit being the bottom dot.
