Question: HP Printer Drivers 5.1 Fail to Install

My HP printer drivers became invalid due to the recent developer certificate issue, so I followed HP's guide to completely uninstall and reinstall the drivers:

https://support.hp.com/us-en/document/c06960563


HP's site says that, for my printer (CP1518ni), I should install Apple's HP Printer Drivers v5.1 package. I downloaded this package from Apple here:

https://support.apple.com/kb/dl1888?locale=en_US


This installer fails with an error: "This volume does not meet the requirements for this update." So now I have no HP drivers at all, and I cannot install new ones.


(Unfortunately, HP's "Easy Start" and "E-Print" drivers don't work for this printer, nor does Air Print.)

MacBook Pro 15″, macOS 11.0

Answer:
Answer:

I had the same problem and could not get the drivers to install. Eventually I used "Pacifist" which installed the drivers to their "default location". I now have a working printer and scanner again.

If you checked the date of that Apple download HP Printer Drivers v5.1, it is from 2017 and could not possibly solve your expired certificate problem. There should be a Software Update that appears on Big Sur (just as it did on Catalina) that offers you the HP Printer Drivers v5.1 Update, which resolves the certificate issue.


Once the Software Update version of the HP drivers is installed, you must visit System Preferences : Printers & Scanners, and with the HP device connected and powered, right click on the printer icon, and choose Reset print system… . You then re-add the same device, selecting certificate updated drivers for it, and then once it is back in your Printers gallery, right-click again and make it the default printer.

Thanks, @putnik! Pacifist did the trick. Once I forcibly reinstalled the drivers from that package, they started working again.


@VikingOSX, I thought the same thing, but HP's document on this failure insists that they just need to be re-installed. I don't fully understand what happened with their dev certs, but I guess they were right.

Apple Support, and Software Update would be two different solutions, with the one coming from Software Update being the latest, and the one from Apple Support Downloads dating to 2017.


Those that applied the HP Printer v5.1 Update following my Software Update instructions were able to regain use of their HP printers.

I have a Canon LBP6030w which also went flakey when I upgraded to Big Sur. The drivers from Canon Support were available, downloaded quickly, and solved the issue immediately when I reinstalled the printer. Oddly, the pages "printed" with no text; though the frames printed there was no content. That was a pain, but it didn't drive me to re-installing the OS to print a damned sales report. HP, though. The old hardware is so durable, but they don't give a darn for Mac OS support.

Once you you have opened the package in Pacifist, you have to copy / paste the files of the package in the corresponding folders on your hard drive (/Library folder which is at the root of the drive, not the one in your User folder). Be careful not to delete the content of the existing folders on your hard drive, but just add the files from the package. Once done, you can install the printer in the settings panel.

Best

Thank you. I used "Install" on Pacifist and I now see the drivers in /Library>Printers>hp. When I open Printers & Scanners and "+" to add a printer, I don't see anything to add. Does the printer have to be physically connected and powered on for it to appear?


Reason I'm asking is I am testing this for my father, who is in another location, and I don't have an HP printer, so I'm testing the process to walk him through it.
