HP deskjet 1050 all in one printer software/driver not found for Mac OS 10.15.7

[esma1234]

Hi, my HP deskjet printer just stopped being able to connect to my MacBook Pro (OS 10.15.7) using the usb adapter.  Everything about the printer, the adapter, etc is fine, except for the software/driver for my printer, as I uninstalled it, and can not re-install it properly since my operating system does not seem to have compatible driver for my printer.  Any idea how to get around this?  Thanks.

I am having the exact issue and I wish that Apple or HP would resolve this ASAP. I was looking through some posts and they mentioned that they got their certificate revoked or something. **bleep**. Need help urgently. I need to print a lot of things.

The solution is to download (and install) this package which will update drivers AND THE CERTIFICATE:
ftp://ftp.hp.com/pub/softlib/software12/HP_Quick_Start/osx/Installations/Essentials/hp-printer-essen...

If the link comes up blank, try right clicking and saving it.

Easy Admin did nothing. Easy Startup did nothing. 5.1 drivers did nothing. This worked for me!

If this solved your issue, please thumbs up and mark as solved!

Hi, I tried this, and at the same time I did reset the SMC and NVRAM as recommended on apple support website, and either that or the above link/installation worked and my HP 1050 all in one printer is working again!  the strange thing is that, when I downloaded the driver/software installation package from the above link, it destroyed itself, not sure if it did anything really, but the bottom line is that my problem is fixed either by this package or by resetting SMC and NVRAM, in the exact steps as listed on the apple website!
