HORIZONTAL MOTION INDEX
This command (also known as HMI) sets the number of
characters per inch (cpi) which the printer will print. Char-
acters are spaced in increments of 1/120 inch. The valid
range of values for the HMI is 1-159 (120 cpi - .75 cpi).
In the command above, "n1" represents the "tens" digit of
the HMI values below 100. For HMI values above 100, n 1
will be a letter from the table below. For all HMI values,
n2 is always the units digit (0-9).

D

150-159
F

For example, 10 cpi means that there will be
a
charac-
ter every 12/120 inch. Therefore, the command to es-
tablish character spacing of 10 cpi would be <ESC>E12.
The command for 1 cpi
(1
inch column width) would be
<ESC>ECO.
Some common settings for HMI are:
<ESC>E08
15 cpi
<ESC> E09
13 cpi
<ESC>ElO
12 cpi
<ESC>Ell
11 cpi
<ESC>EI2
10 cpi
Invalid parameters are ignored. Zero digits MUST be en-
tered, i.e., both n1 and n2 must have values entered whether
the
HMI
value is "9" «ESC>E09) or "120" «ESC>ECO).
