Basic questions about Zebra printers

¡Hi everyone!

 

I need to understand how to print labels with a Zebra GK420t printer. The only software I have is "ZebraDesigner for XML" and I have been able to design and print single labels with statict text, but what I need is to print a series of labels that you can use in laboratory work in a daily basis, e.g labels of samples with different ID from a data base. What I've done so far is to use data in MS Excel to create labels using MS Word 2010, which works well, but now I need to add QR codes to those labels.

 

To my understanding, I should be able to do that by using variables in ZebraDesigner, but I have no idea how to connect my data with the labels. I think there's something about programming in ZPL, but I can't figure out how, and most ZPL manuals have not been useful to me.

I'm sorry if these is a very basic problem, but I have not previous experience with label printers and I have nobody to ask (the printer was buyed in 2015 and nobody have figure out how to make it work properly).

 

Thank you in advance for any kind of help
