Just a quick suggestion: I'd try
1. quit Archicad and any pdf reader/printer software you're using (Adobe, Aymuni etc)
2. Re-install the font in question using the original source
3. Re-start the machine
were you able to resolve this issue regarding the font?.. I had similar problems once before except when a consultant received my pdf files he had replied that font was disoriented and not legible in which I had to embed the font within the pdf (Adobe, Aymuni etc0 settings.) if you were able to fix your problem disregard this post. If not reply and I could give you a step by step example.
Haven't worked it out yet. Was suggested to reinstall the font. Not quite sure how to do that. If there is a procedure for embedding the font into the pdf file I would be interested in trying that. Thanks!
The pdf printing is acting as described -- somthing shows but not legible. I tried a different font which then does work. Would like to keep with the tekton pro (architectural type) font. If there is a similar Windows type font available I would be interested in using it to make it work.
