When viewing the HTML page in the browser, the barcode label is correctly displayed. When printing the barcode label, however, it displays lines in between. This happens only with Internet Explorer 5.5; it works fine on Internet Explorer 5.0 and above.

Microsoft no longer supports IE 5.5, please upgrade to a newer version. Several different methods of creating online barcodes are explained in IDAutomation’s Internet Barcode FAQ and Free Online Barcode Creator.
