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.
