<How to obtain attribute "a">
Attribute "a" is obtained in the following manner.
-
As shown in the figure below, attribute "a" consists of descender data and
proportional data. The descender data determines whether or not the 9th dot will
-
be struck, and the proportional data determines the starting and ending positions in
the print area.

In the above figure, the high-order 3 bits of 7-bit proportional data represent the
starting print position and the remaining 4 bits indicate the ending print position. In
this example, attribute "a" is:

<8B>H
=
(139)D
- NOTE:
A maximum of 12 horizontal positions can be defined in a download character.
- However, the 12th position is automatically set to O. The minimum width of a
download character is 5 positions. Example programs are described in the following
