Deactivate automatic
line feed
If automatic line feed is activated, the printer also executes a line
feed when a carriage return command is received. This function can
also be controlled via the menu item Auto LF.
Function
Start unidirectional
printing
Stop unidirectional
printing
To optimize throughput, printing of lines normally takes place al-
ternately forwards (from left to right) and backwards (short line
seeking, bidirectional printing).
In order to improve the alignment of lines lying underneath one
another you can stipulate with this function that each line be print-
ed starting from the left margin (unidirectional printing). You
should use this option when precise vertical alignment of the indi-
vidual lines is desired (bit image graphics, IBM graphic characters,
tables).
