Font Bitmap Data
Format
The black and white bitmap that represents the
font must be converted into ASCII hexadecimal
code. The 0° font format has dot converted to
data bytes reading from left to right and the last
byte in a line is padded with zeros to complete
the line and data byte.
The 0° and 90° font data is then sent to the
printer in line order.
