how to generate and print 20x20 datamatrix barcode using labview?

Along with the barcode certain datas are to be added to the right of it.

We have previously used Zebra barcode printers - they have some software (Bartender) that allows you to make ActiveX calls to populate a barcode template with data and print it.

Which printer are you using ?

Hello,

You can use an external tool (e.g. Zint Barcode Generator) or an online service (e.g.http://datamatrix.kaywa.com/ ) which can generate a datamatrix picure and load that picture into LabVIEW.

I use a .NET dll file found at http://www.onbarcode.com/products/net_barcode/.

It is a trial application and occasionally adds the word trial across the barcode.  I get around this by searching for red pixels and if I find one, I just regenerate the barcode until no red pixels found. It's very quick.

Thanks to your reply. I'm using ZEBRA Zt410 printer.

could any one tell me how to generate a 20x20 data matrix using labview.

Since you started a duplicate thread - I'm going to continue in here.

We have given you a number of different options to generate/print a barcode using LabVIEW.

Do you have the Bartender software installed with the Automation (ActiveX) option? Can you print a label from within the Bartender Software? Do you know how to call ActiveX functions in LabVIEW? For the latter, if you Google 'calling ActiveX LabVIEW' you will get a lot of results. Once you know how to do that, you just need to know which Bartender ActiveX functions to call.

I've attached a couple of screenshots from some quick code my colleague put together before to initialise Bartender, open a label template, fill in a field and print a label. Don't forget the close the references when your application exits. For more information you'll need to read the Bartender documentation.

I need to generate data matrix barcode using labview, i dont need to generate a barcode from other application and call that barcode into labview.

i know to call activeX functions.I also used actixeX option (windaq apllication), i have bartender software installed but the thing is that i dont have batender software installed with activeX.

You need to find a VI that someone, somewhere created a means to go from text to the barcode image.  There's a good chance such a VI doesn't exist.

Otherwise you need to figure out the encoding scheme behend this barcode and create a VI yourself that does this.

They are the one 2 things you can do if you don't want to use some external program that is already written to do this.
