Hello,
I had the same problem with one of our computers (we have 2 businesses & 2 separate computers). Both computers have Windows 10 & QB Desktop 2021 and Computer 1 printed both the 1096 & 1099s just fine, but Computer 2 would only print the 1096. I ran the QB Tool Hub, did updates and tried everything mentioned in forums but nothing worked. I finally decided to uninstalled Adobe Acrobat DC and reinstalled it. IT WORKED!!!! I hope this helps.
