You can set defaults for these on your account's settings page

1. Find the desired product and click the "Edit" button
2. Go to the Label Display Settings section
3. Select "General"
4. Fill-in the "Font URL" field with a link the CSS font definition, e.g. https://fonts.googleapis.com/css2?family=Open+Sans
5. Fill-in the "Font family" field with the font's family name, e.g. Open Sans
6. Click Update

The URL must be a CSS font definition to be included via a link HTML tag, not a font file.
