Jerry, this helped me when I was having the same problem. I can’t reproduce it now but sure enough “print to file” was checked! This is all I can tell you though.

What should I do if Acrobat Reader DC is asking to save a file when a document is printed?
In case Acrobat Reader DC is prompting to save a file when you click Print, then click Advanced print dialog and deselect the Print to File option.


Make sure that you have selected a physical printer to print upon and not Adobe PDFXPS/Send note or any other virtual printer.
Print to File option was available on Print dialog itself until Acrobat 10.X versions.
