The black and white bitmap that represents the character must be
converted to hexadecimal code. The bitmap is described line by line
from left to right, starting from the upper left corner of the character
cell. A white dot is represented by 0 and a black dot by 1. Each byte (8
dots) forms a binary number that is converted to hexadecimal code.
The last byte in a line is padded with zeros to complete the line and
data byte. The data is the sent to the printer as a continuous string of
hexadecimal byte representations in line order.
You can also download soft fonts to the printer using Intermec
LabelShop or Intermec InterDriver.
You can list soft fonts using the EI command.
