Need macOS Sequoia 15.4 driver for HP Officejet Pro X476dw MFP

Addendum to above posting: I don't know for sure that the problem wasn't already present in 15.3. I was getting ready to install 15.4 on the MBP 16 M1 and so was using the already upgraded MBP 15 Intel to print some shared documents. Had I tried to print on the same machine before upgrading it, the problem might have appeared then.

Thanks for your reply. I didn't want to perform the installation via iOS, as HP Easy Start.app suggested, because I was quite sure that, whatever it does, it doesn't install anything on the MBP, which is where I'm experiencing the problem.

More to this saga: I make weekly backups of the machine with SuperDuper! Yesterday I decided to boot the last backup (of 15.3.1). My plan was to then use SuperDuper! to clone the clone to the MBP, effectively downgrading it fro 15.4 to 15.3.1. I would then boot the machine normally, and try to update the printer stuff using HP Easy Start.app. Unfortunately, the MBP would boot the clone. Something about an error, trying again. Since I had set thee boot disk in the System Settings before shutting the MBP 15 down, it just looped and I finally had to hold down the Option key while start to get back to the internal drive. I have never had a problem booting a clone, and I've been using SuperDuper! for as long as I've been using Mac's, it seems. Certainly since Apple's switch to Power PC. So my guess is, something has been changed by the upgrade to 15.4 in the firmware.

Thanks, DrewM, 4tbraun. Will try this later. Unfortunately, my HP OfficeJet Pro X476dw MFP has a printing problem that wouldn't seem to have anything to do with a driver. I'm trying to print an 11-page PDF document on A4 paper with large graphic areas (e.g., the complete page width x half the length of the page in portrait orientation). Even on the first page there is evident streaking about 2 cm wide on the right of the printed area., but after three pages like this it suddenly becomes much worse, until even the (black) text beneath the affected area in the graphic is totally missing. I have tried the built-in cartridges cleaning tools, even at the 3rd of 3 levels, but the problem persists. I've found a video demonstrating how to clean the print heads, but I can't see clearly from it what exactly the person is calling printheads. Just poking around in the general area seems predestined to damage something. So it looks as if I need to buy another printer, and you can bet your bottom dollar that it won't be HP, and maybe not even inkjet.
