In version 3.4.2 the method toPDF() calls “http://cdn.webix.com/extras/pt-sans.regular.ttf” (line 35386 in webix_debug) but that file does not exist on your CDN.
(earlier versions loaded “http://cdn.webix.com/edge/fonts/PTS-webfont.ttf” which does (still) exist on your CDN)
Thank you for reporting the issue. Please, check it again - it should be working now.
it works indeed, thank you !
