Hi Vinay,

Generally you write direct to device.

You need to know the language that the printer works.

A common used printer is Zebra that has a proprietary language called ZPL:

Healthshare documentation:

After you setup the device  you need to use then:

Hi Vinay,

In this case You need to write the postscript to the printer.

Maybe this project can help you: https://github.com/bwipp/postscriptbarcode

Like Stephen suggested, but without using ZEN Reports, you can  use the the library Barcode4j: http://barcode4j.sourceforge.net, (this library is used by the Zen Reports), you can use Java Gateway to call the library direct from your COS code.
