So add up the values of the dots in each column using this
system. In Figure 6-8 we’ve shown our grid with the sums of the
columns filled in across the bottom (see if these agree with your
answers!). Across the top of the grid you’ve probably noticed
the cryptic labeling of each column: ml, m2, m3, etc. These
labels correspond to the labels in the command syntax state-
ment, which we’ll get to shortly.

n Assigning a value to your character
We’ve done a pretty through job of designing and describing a
user-defined character. But this printer has room for 96
download characters - how does it knows which standard
character we want to print: every character is assigned a unique
number.
The standard characters are assigned the ASCII codes -
numbers from 0 to 255. For the download character sets you can
also define any positions between 0 to 225. This means that
once a character is defined and assigned a value (and the
download character set is selected, you can use that character
on the printer the same way you would any standard character.
You can send the character with the same ASCII value. You can
