Postnet, also known as USPS POSTNET Barcode, USPS POSTal Numeric Encoding Technique Barcode, is a delivery point barcodes adopted by United States Postal Services.

Generate and create Postnet barcode using Java is one of the functions in OnBarcode's Barcode for Java Generating Java library (jar file), which supports generating & printing Postnet and 20+ other linear & 2D bar codes in Java application and software.

Postnet Generator and Reader library, SDK & application
Postnet Generator components and software include .NET POSTNET Generator, C# POSTNET Generator, VB.NET POSTNET Generator, ASP.NET POSTNET Generator, POSTNET Generator.

This document is providing a detailed Java sample source code about generating Postnet barcodes in Java class using Java Barcode generation component. Complete Postnet custmoization settings is included in Java Postnet generating guide.

Generating POSTNET barcode in Java class example:

	Postnet barcode = new Postnet();
	
	/*
	   POSTNET Valid data char set:
	        0, 1, 2, 3, 4, 5, 6, 7, 8, 9 (Digits)
	
	   POSTNET Valid data length: 5, 6, 9, 11 digits only, excluding the last checksum digit
	*/
	barcode.setData("01234");
	
	// POSTNET Short bar vs high bar ratio
	barcode.setShortTallRatio(0.4f);
	
	// Unit of Measure, pixel, cm, or inch
	barcode.setUom(IBarcode.UOM_PIXEL);
	// barcode bar module width (X) in pixel
	barcode.setX(3f);
	// barcode bar module height (Y) in pixel
	barcode.setY(75f);
	
	// barcode image margins
	barcode.setLeftMargin(0f);
	barcode.setRightMargin(0f);
	barcode.setTopMargin(0f);
	barcode.setBottomMargin(0f);
	
	// barcode image resolution in dpi
	barcode.setResolution(72);
	
	// disply barcode encoding data below the barcode
	barcode.setShowText(true);
	// barcode encoding data font style
	barcode.setTextFont(new Font("Arial", 0, 12));
	// space between barcode and barcode encoding data
	barcode.setTextMargin(6);
	
	//  barcode displaying angle
	barcode.setRotate(IBarcode.ROTATE_0);
	
	barcode.drawBarcode("C:\\postnet.gif");
