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:

After you setup the device you need to use then:

You could also use ZEN Reports and the <barcode> element to render a number of barcode types

Hi Cristiano,

I am able to write the data on device directly from cache . I don't wan't to print barcode on barcode (zebra) printer. I want to print on A4 size paper from lazer printer through cups printing.

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.

Vinay, the typical approach to send to CUPS for TrakCare would be to use Zen reports or JReports. TrakCare's EPS print server can run the report automatically and send the result to the configured printer through CUPs.
