public EscPosBarcode textPrintingPosition(byte textPrintingPosition)

Selects the print position of Human Readable Interpretation (HRI) characters when printing a bar code.

Parameters:

textPrintingPosition -

height

public EscPosBarcode height(int n)

Sets the bar code height to n dots.

The original ESC/POS Manual defines the bar code height in dots, but the actual size of a dot and the default value for n and may differ for each device.

For instance, the default bar code height for devices with dot size of 0.125mm (1/203 inches) is 162.

Known default values:

Datecs DPP-350: 162 Leopardo A7: 36

Parameters:

n -

Returns:

width

public EscPosBarcode width(int n)

Sets the bar code width.

The units for n depends on the printer model - usually 2 ≤ n ≤ 6 with default value 3.

Known models range and default values:

Datecs DPP-350: 2 ≤ n ≤ 4 with default value of 3 Leopardo A7: 1 ≤ n ≤ 4 with default value of 2
