Product: HP Photosmart C4480
Operating System: macOS 10.14 Mojave

Error message: 

"One or more components of the HP printing software are corrupted or missing. The print job cannot be completed. To fix this situation, HP recommends reinstalling the print driver software. " I downloaded HP driver, but got this message: "The package was signed with certificate that has expired.  If you acquired this package recently, it may not be authentid.  Do you want to continue with installation anyway?"   Apple software update certification expired 10/24/19.  Afraid to install new driver.  This happened on two different older HP Printers and two different MAC desktops.  Running both Macs on Mohave 10.14. Help please.  Do I uninstall my software and then install new driver?  Crippled at the moment. Thanks for help
