- Method Detail
  - textPrintingPosition
```
public EscPosBarcode textPrintingPosition(byte textPrintingPosition)
```
    Selects the print position of Human Readable Interpretation (HRI) characters when printing a bar code.
    
    Parameters:
    
    textPrintingPosition -
    
    Returns:
  - 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

Parameters:: n -
Returns:

write

public void write(java.io.OutputStream out)
           throws java.io.IOException
```
