PRINT DIRECTION

ESC U			Unidirectional/Bidirectional Printing
ASCII:	ESC	U	(n)
Control:	CTRL [	U	(n)
Decimal:	27	85	(n)
Hexadecimal:	1B	55	(n)

Causes the printer to print unidirectionally or bidirectionally. n indicates which is selected as follows:

•n = 1 or 49: Unidirectional printing

•n = 0 or 48: Bidirectional printing

When unidirectional printing is selected, data is printed only when the printhead is moving from left to right. Printing this way improves vertical character alignment.

When bidirectional printing is selected, data is printed when the printhead is moving in both directions. This is the default print mode.

Note: If set to ON, "PRINT STYLE, Bi-Directional Graphics / NLQ" in the configuration menu overrides unidirectional printing.
