Product: HP OfficeJet 4650 All-in-One Printer
Operating System: macOS 10.13 High Sierra

I had no problem printing two-sided until I switched to a different HP printer.  Now the 4650 printer no longer shows the two-sided button when the "print" screen comes up.  I have tried solutions that appear in this forum and on the HP site and they haven't helped.  Based on one suggestion, I shut down the printer, unplugged it, and restarted it.  Didn't help.  I went to the touch screen on the printer, pressed copy, pressed settings, and pressed two-sided.  Didn't help.  When I open the printer driver the settings button is the only button that isn't highlighted, so I can't click on it.  I downloaded new software and it didn't make a difference.  However, during the download a pop-up screen appeared temporarily that said that the installation of an "extension" was not allowed, so I should start over.  The same thing happened when I tried again.  It's frustrating because nothing seems to work.
