The most significan bit of the attribute byte is 1 if the character is an
ascender (positioned entirely above the baseline) or 0 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 at-
tributes are used only in proportional spacing.
Each data byte indicates eight vertical dots, with the MSB being the top
dot and the LSB the bottom dot. These correspond to pins 1 to 8 or 2
to 9 of the print head, depending on whether the character is an ascender
or descender.

Defines one or more new NLQ characters and stores them in RAM for
later use. DIP switch 2-l must be OFF. NLQ mode must be selected before
this command is executed. The parameters are the same as for the draft
download character command except that the attribute byte specifies right
space instead of character width and the dot density is doubled in each
direction, so each character consists of 16 dots vertically and 23 dots
horizontally and requires 46 data bytes. Dots defined by ml to m23 are
printed on the first pass of the head. Dots defined by
m24
to
m46
are printed
on the second pass, the paper being scrolled up half a dot between the
two passes. For further details, please refer to the Appendix C.
