Wow, first thanks for that effort and second MOST interesting!
(FYI: my first platform is also 10.13.6, and yes, it's failing on that.)
But, my testing on the 10.14 platform was also with a "dummy" return having essentially nothing, just tried to print the "Personal Information" page to no avail.
The "real" returns do indeed have numerous other income sources, lots of Schedule B and D entries, a few other complications as well, but again, that being a cause is difficult to see.
This issue is actually present in numerous different returns, most of which are ONLY Federal and MA (that's where this problem first occurred), then one with VT as well.
With your result, I will back up and try again with some very simple dummy setups, but there is something clearly curious here.
Lastly, thought it might be related to the printer, but the 10.13 and 10.14 platforms have DIFFERENT printers - what "printer" are you referencing?
Thanks again, let me see if I can make some headway based on your finding....
