Hey @Lucie, the way you worded this question can be construed several ways, so I offer the following to help.
LightBurn uses the fonts you have installed on your computer, the same fonts you can select from your word-processing application. You can add fonts at any time using the process defined by your computers OS. Google can help with this.
We also offer a support for a special type of fonts known as SHX fonts. There are designed differently than “regular” fonts and are unique in that only single lines are used to create each letter shape, designed for Laser and CNC output. This video explains what they are and how to install and use them in LightBurn.
