Enum Class Align

java.lang.Object

java.lang.Enum<Align>

io.github.chkrishnatej.rp3200.Align

All Implemented Interfaces:

Serializable, Comparable<Align>, Constable

public enum Align
extends Enum<Align>

Horizontal alignment of a printed line (ESC/POS command ESC a n).

ESC/POS printers only honour an alignment change at the start of a line, so switching alignment in the middle of a line takes effect from the next line. Alignment also positions QR codes and barcodes.

In templates, use the [left], [center] and [right] tags instead.
