Controlling the configuration of the printer Standard commands

Selecting unidirectional printing for one line
Function:
Via ESC < the next printing line is printed from right to left. This command will be
cancelled automatically by a carriage return (CR).
Switching the unidirectional printing mode on/ off
Function:
Normally printing is bidirectional (optimal printing path). Unidirectional printing
(printing in only one direction) is sensible, for example, inorder to ensure a pre-
cise positioning of the characterswhen printing a text or graphics, thus to produ-
ce a neat print format.
ESC U (n) activates or deactivates unidirectional printing, by which n serves as
an on/ off switch:
n=1activates the mode (unidirectionalon),
n=0deactivates the mode (unidirectionaloff).
Example:
Afterprinting three lines, a change is to take placebetween bidirectional and uni-
directional printing. Bidirectional printing begins.
