Quoting from the manual at the web link shown:
Changing the Language (Windows Only)
You can change the display language for the DYMO Label software so that you can work
in a language that is most familiar to you. Changing the language only affects the text and messages in the software. Features available in the software are determined by the operating
system locale.
To change the display language
1. Choose Preferences from the Edit menu.
2. Select the General tab.
3. Under Language, select the language you want.
4. Click OK.
The language changes immediately without restarting DYMO Label software.
If it's the USB port on the computer, try just using another port. If it's the label printer itself, you may need to contact the company to see if replacement parts are a available. I think I would just purchase another printer since they aren't any more expensive than they are.
You should have the text box to type in. You can click on the dotted line and move the whole box up or down so the entire text will be mostly centered on the label.
The default language is usually set to English. Turn machine on press "settings" and use the up or down arrow keys to select LANGUAGE and press "OK" use the up and down arrow keys to select the language you want and press "OK". Hope this is of some use to you.
