The JSP already has the meta tag But it looks like PD4ML is ignoring it. Tried adding all the fonts and that also didn’t work. Any ideas? PD4ML July 24, 2017 at 16:51 #30095 Sounds like needed TTF fonts are not embedded to PDF or the TTFs do not define the mathematical character glyphs. Please send a sample HTML and its resulting PDF to support pd4ml com Author Posts Viewing 2 posts - 1 through 2 (of 2 total) The forum ‘HTML/CSS rendering issues’ is closed to new topics and replies.
