Have you restarted the computer since the issue began?    

No, but I will try.  I was able to print a 2019 return, but not the 2018.  I will try right now. 

Did you recently install a Window 10 update? 

That has messed with my drivers - which really *isn't* Intuit's/ProSeries fault.

I tried shutting down.  Still did not work.  

I probably did install a windows 10 update...not sure but I have everything updated automatically.  What did you do about it?

And youre sure its not printing to PDF by mistake? (Ive done this many times)

At the top of the Print window its set for Printer, not File (PDF)?

No, I checked that.  I tried to print to PDF last week but I was not able to e-mail it to them.  It came up in my Documents  but would not e-mail. That is why I am having to print them a return for them to pick up.  I feel like a fool.   So now while I am trying to print, I even unchecked the PDF and the DMS.  (I don't even know what DMS is).  I am really frustrated.

Also, this client is not the only one who I can't print.  I tried others.  I can print 2019 just fine.  It is only the 2018.  

As a work-around, can you print to PDF, then open to the PDF and print the PDF?
