It has a lot of time and nerves and numerous Google queries used until I had the LabelWriter extent that it has postage printed with addresses so that I just had to stick the labels only to the letter. The uninitiated can be revealed's so him not so goes like me: you have to go to properties and then shimmy to the label format and select the correct printer menu by right-clicking. Officially documented which is nowhere.
The follow-up costs are quite high, if one takes the Dymo labels. In third-party prices are bearable, but the print quality is not outstanding.
