The software to create the labels obtained free of charge from the website of Avery as a download. This offers the possibility to obtain a design template within Microsoft Office or the complete program as a download. The LabelAssistant of Zweckform is not really comfortable, but you can basically create the design for the labels.
By sticking the labels first I was still a bit of a problem, because not accompanied by a centering aid. While the labels have retaining tabs, but it's still not easy, the label really clean to center.
But all in all I am satisfied with the solution. The labeling is better and cleaner than with a felt pen in any case. And the printed result is convincing.
