Acrobat will not print

Help!  I am using WIndows 10 and until now I have had no problems printing from Acrobat.  However, I have just tried to print off several PDF files and Acrobat keeps going to the Save As screen and will not print.  I have tried to print old files with the same result.  I looked at the 'Print to File' check box and it was not ticked.

In trying to overcome the problem I have ticked the 'Print to File' box, clicked on OK, exited Acrobat and then opened it again, unchecked 'Print to File' and OK'd it - still the same result.  I therefore uninstalled Acrobat and reinstalled - same result.  

I just don't know what to do next.  Can anyone help please?
