PostNet

  • 2 minutes to read

PostNet was developed by the United States Postal Service (USPS) for faster mail sorting and routing. Unlike most other bar codes where data is encoded in the width of the bars and spaces, PostNet encodes data in the height of the bars. PostNet bars have the same width but different heights.

using System.Windows.Forms;
using DevExpress.XtraPrinting.BarCode;
using DevExpress.XtraReports.UI;
// ...
public XRBarCode CreatePostNetBarCode(string BarCodeText) {
    // Create a barcode control.
    XRBarCode barCode = new XRBarCode();

    // Set the barcode's type to PostNet.
    barCode.Symbology = new PostNetGenerator();

    // Adjust the barcode's main properties.
    barCode.Text = BarCodeText;
    barCode.Width = 400;

    Bands = {
        new DetailBand() {
            Controls = { barCode }
        }
    }
