Hershey Text is an Inkscape extension for rendering text with engraving fonts. Versions have been included as part of standard Inkscape distributions since version 0.91.
A new version, https://www.evilmadscientist.com/2019/hershey-text-v30/ Hershey Text v 3.0], has recently been released and is included with the current versions of both the AxiDraw software and the EggBot software. It will be included in Inkscape, starting in Inkscape 1.0.
