I lie most significan bit o f 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
mount o f white space to the left o f the character (0 to 7 dots, specified
ii
by bits 4 to 6), and the width o f 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.
l ach data byte indicates eight vertical dots, with the M SB being the top
dot and the LSB the bottom dot. These correspond to pins 1 to 8 or 2
to 9 o f the print head, depending on whether the character is an ascender
or descender.

space instead o f character width and the dot density is doubled in each
direction, so each character consists o f 16 d ots vertically and 23 dots
horizontally and requires 46 data bytes. D o ts defined by
