Me Too!!

Using a Photosmart D7400 series that literally worked yesterday. 

So HP's solution is to send us to a 3rd party, unsupported open source site and hope?  

That's pretty lame.  On the apple support site, Apple seems to blame HP: https://discussions.apple.com/thread/251951948

Is this a temporary fix to send us out to Guttenprint?

Having this same problem on our HP Deskjet 2512. Have r2einstalled as others have and nothing. We are both using MacBooks running with Catalina. My  husband was running on Mojave until he got this problem and installed Catalina. So problem was with Mojave, too.

That is not the solution it seems, although perhaps A solution.

This thread has an HP driver package that worked for me.

Linking to that package and installing it looks like it adds an HP Utility application.  Adding the USB printer with that application doesn't look like it actually adds the printer to the System, and a test page doesn't print.  Is there another step to take?  Thx.

I installed that package on my Mojave MacBook Pro, after deleting the printer from my system preferences, then restarting. 

then I added a new printer, selected my photosmart D7400 series, and it worked fine on Mojave for me. 

I did the same thing on my wife’s notebook running Catalina, and it did start printing again, although it threw out a bunch of errors that “XXX will damage your system”. But it got us up and running for now.

Thanks Bryan, That did work. I did have to delete my printer and re-add it. I also got a weird error message while printing but it did work. Thanka again!

Glad to be of service!
