I'm sorry for the frustration. First, the latest version is wPro.2020.07.00.18.  Can you confirm you are on that, via Help -> About, Version?

Second, can you specify..

- Are you printing via "Print Selected Forms"-> Letters Only?

- What happens when you hit the print button? Nothing? Or do you you get the print confirmation dialog, but nothing outputs to the print? If so what does the print confirmation dialog say?

- Can you try printing to file? (Choose Print, Check File (PDF))
