These files hold templates to be used with the Label applet or the Labeller applet. As enveloppes are mostly fed sideways int a printer, the templates EnvB6 and EnvB5 have been set up in this way. For these 2 templates you need to have the addressees name and address selected in th OvPro document. Then select the the correct template (Menu>Applets>Label>, then click on the Label applet icon on the Button bar. A document is with the addressees name and address inserted. This document can be edited before you print it. The other templates are for Zweckform labels, comparable to the Avery labels, but found in German speaking countries.
