ters, and this command is ignored. Draft mode must be selected

nZ is the character code of the first character defined and n2 is the
character code of the last character defined. nZ must be equal to or
less than n2.
Each character is defined by an attribute byte (m0) and 11 data bytes
(mZ,m2,...mZZ).
The most significant bit of the attribute byte is 0 if the character is
an ascender (positioned entirely above the baseline) or 1 if it is a
descender (descending below the baseline). The attribute byte also
indicates the amount of white space to the left of the character (0 to
7 dots, specified by bits 4 to 6), and the width of the character cell,
including this space (4 to 15 dots, specified by bits 0 to 3). The left
space and cell width attributes areused only in proportional spacing.
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.
