When you design or print your labels, you can face the following issues:
Problem 1
In NiceLabel Desktop Designer you can't select printer internal fonts.
Problem 2
When printing to a remote printer, printer fonts or third-party TTF fonts convert to Arial or some other default Windows font.
Solution 1
The Blocking Untrusted Fonts feature prevents using printer fonts or third-party TTF fonts. Your system administrator can disable or limit this feature. Read more about the Blocking Untrusted Fonts feature in the Microsoft article.
Solution 2
Install printer driver locally on a computer where the remote printer is connected.
