Causes printing to occur from left to right for one line only.
1B 55 n
27 85 n
Causes printing to occur in only one direction of shuttle
movement (left to right).
Where:
n = NUL (hex 00) or 0 (hex 30) turns unidirectional mode off
n = SOH (hex 01) or 1 (hex 31) turns unidirectional mode on
Printing normally occurs in both directions of shuttle movement.
Unidirectional printing slows the printer down approximately
50%, but it is sometimes used when very accurate dot
placement is desired in graphics.

Enables the extension of the character bitmap so that they
touch in both horizontal and vertical directions as follows:
•
n1 = 1 or 49, n2 = 1 or 49 Normal character
•
2 < = n1 < = 4 or 50 < = n1 < = 52, n2 = 1 or 49 Double height
character (same with FS ! 8)
•
n1 = 1 or 49, 2 < = n2 < = 4 or 50 < = n2 < = 52 Double width
character (same with FS ! 4)
•
2 < = n1 < = 4 or 50 < = n1 < = 52, 2 < = n2 < = 4 or 50 <= n2
< = 52 Double width and double height character (same
with FS ! 12)
Where:
1 < = n1 < = 4 or 49 < = n1 < = 52
1 < = n2 < = 4 or 49 < = n2 < = 52
The default is normal character.
