The entire word (character) descends by one dot in case of DP, and by two dots

in case of LO.
Not used.
When the 8th bit of the DP character pattern dot column is set or 16th bit of the
LO character pattern dot column is set, the dot column descends by two dots in
case of DP, and by four dots in case of LO.
This defines the spaces preceding and following the character to be downloaded. A character
has 9 horizontal dots in the case of DP, and 27 horizontal dots in the case of
LQ.
Such dots are followed by a space of 3 dots in the case of DP, and a space of n dots in the
case of LQ, to provide a space before the next character. Consequently, to down load a font
unique to the user, this space must also be considered except if a character is connected to the
next character such as in CG graphics.
Item 4) shows such an example.
It is not necessary to code the space as data in down loading.
Space is defined by one byte; the higher 4 bits define the preceding space, and the lower 4 bits
the following space.

This means data corresponding to each dot column of the character pattern to be loaded, and
is coded in hexadecimal or decimal notation.
The following figures show the relationship between dots and data representations.
