Failed to open a connection to the device (-21345)

Did you install the package I linked to already?

Try that, then restart. Then uninstall and reinstall the printer through Printers & Scanners. If you can't re-install, try getting the 5.1 driver package, restarting, and trying again. Let me know how it goes:  https://support.apple.com/kb/dl1888?locale=en_US

I downloaded the software package from your earlier post & installed it. I got printing back but not scanning. I uninstalled/installed in System Preferences but scanning still not working.

At this point I am unsure of what next steps to take.

I appreciate your help. It is 10:25p on the east coast. Whatever you suggest will be tried tomorrow.

Thanks again for your time & help.

If you installed the 5.1 I linked above, and then reinstalled using system preferences, I would see if any HP software is available for reinstallation. What model device is this?

[Mpk7]

HP Officejet Pro L7500. I tried the driver software from HP but it had the expired certificate.

I will try another go at this in the morning.

[BryanCustomPure]

Install that one (with the expired cert) and then the package I linked to. Let me know.

Things seem to be back to normal at this time.

Thanks again for your time & help.

I went to 'HP Customer Support - Software and Driver Downloads'

and downloaded the driver. It worked.

I have an officejet 6500

Thanks a lot BryanCustomPure.  I followed your steps in resolving my printer/scan connection issues and it worked out well.  I am now able to scan my documents without any connection failures.  Keep up the great work.  😊
