However, the print position cannot be reset beyond the left margin.
With this command specially composed symbols which are not
available in the character set used can be printed.
Function Dec. Hex. ASCII
Delete buffer 24 18 CAN
This command deletes all printable characters in the line buffer.
Functions set by commands are not reset, nor is the receive buffer
deleted.
Function Dec. Hex. ASCII
Activate automatic 27 53 49 1B 35 31 ESC 5 1
line feed
Deactivate automatic 27 53 48 1B 35 30 ESC 5 0
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 Dec. Hex. ASCII

Stop unidirectional 27 85 40 1B 55 30 ESC U 0
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).
