Section 7: Downloading Characters and Fonts
112
Attribute byte 2 specifies proportional-spacing information. Bits 6-0 specify
spacing information. Set these bits to 0 if proportional spacing is not desired.
When you use proportional spacing with a downloaded font that has bits 6-0 set
to 0, all 11 bytes of character data print.
Bit Bit Values Functions
7 Set to 0.
6, 5, 4 Interpreted as a binary
number.
Specifies the number of leading dot
columns to ignore. This number is the
offset. Up to 7 dot columns can be ignored.
3, 2, 1, 0 Interpreted as a binary
number.
Specifies the number of dot columns to be
printed. Each character is automatically
followed by a blank column that is not
included in the character width. Widths
greater than 11 will be treated as 11.
Printable
Data
(Bytes 3
through
13)
Define the printable data. These bytes are unique to each character,
and must be specified for each download
character. The printer prints one byte at a
time. Each wire in the printhead has a
corresponding bit in each byte, depending
on whether the character is an ascender or a
descender. To print the dot, set the bit to 1.
