If your Intermec printer is running in Advanced mode (dot size of 2.5 or 5
mil), UDCs must be downloaded to the printer in the six bits per byte
format.
The six bits per byte format is more compact than one bit per byte. When
you use six bits per byte, you can download large graphics more quickly.
The difference between 2.5 mil and 5.0 mil modes is the size of the image
when it prints.
The arrangement of the bits is very important in this format. Eight bits (0
through 7) compose every byte, but the printer only uses bits 0 through 5
to map the image.
You must always set bit 6 (the seventh bit) to 1 so you can download data to
the printer. 7-bit hosts reserve bit 7 (the eighth bit) for parity and
compatibility, so the range of characters for any given UDC is 40 hex (@)
to 127 hex ( delete character).
The next procedure describes how to create a user-defined character in the
six bits per byte format for use in Advanced mode.
To create a user-defined character for Advanced mode
