Character Height and CPI
This sequence allows you more control over how characters will look when they are printed out
on the printer. With this command you can change both the character height and the character
width. This allows you to print in wide characters for increased readability. To change character
size, use the following escape sequence:
ESC [ n1 ; n2 Sp B
1B 5B 3B 20 42
Where:
n
1
= one of the values from the following table.
n1 values Char Height
ASCII HEX amount of increase
100 313030 = normal height
200 323030 = twice normal height
Figure 8 – Character Height Multipliers
Note: Changing the height of a character set will change the distance the
paper moves in response to a Line Feed Command.
n
2
= a width multiplier in the range of 1 (.01x) to 1000 (10x). For example, a
value of 50 would be .50 X 10 CPI = 5 CPI, and a value of 200 would be 2.00 X
10 CPI = 20 CPI. The result is variable to within a decipoint, so that a value of
128 would be 1.28 X 10 CPI = 12.8 CPI.
The table above lists all of the available CPIs on this emulation and the values used to select
them. This command will work with any alphanumeric font.
A new CPI selection will cancel the horizontal size selected with this command, and selecting a
new horizontal size cancels the previous CPI selection.
