I have this same problem. I have a Mac, fully updated, printer works fine with other things. I updated my turbotax desktop software. I asked it to save it as a pdf. When it asks you to name the file it comes up 'JoeShmoe24' Change it to JoeShmoe24.pdf and it will save it properly. Then you can print. As for printing from their desktop, definitely an issue there that they need to fix.
