Without an example of exactly what the output looks like all we can do here is guess. Upload an image to imgur.com and post the link here.

One thing comes to mind. With most colour printers when you start to print a document you get to choose some options for this particular job. For any that are ONLY black ink jobs like text or line drawings, I always tell it to print Black ONLY for two reasons. BOTH of these are because the printer's default setting is to print using all colours, and BLACK in that mode means it will print ALL FOUR colours of ink. This wastes the three colour inks AND means that too much ink is used not always exactly lined up with each other so it can be a bit fuzzy. See if you can find the black-only printing option for text documents.

Next item is this, since some of your docs WILL have colour and need all four inks. Look through your manual for a maintenance process to adjust the ALIGNMENT of the ink nozzles. Many printers have a self-adjusting process you can trigger manually for this adjustment. It is to ensure that each colour of ink that is supposed to line up with the other colours actually does that.

Last thought is about paper. At one time you needed special ink jet papers to use such a printer, and you still need special paper for good PHOTOS. But these days for simpler jobs you should be able to use any good copier grade of paper, especially if the paper claims to be multi-purpose. But really cheap paper may NOT work well because it lacks a surface treatment that prevents ink from blotting.

If you can't print an alignment page, that may be because HP doesn't allow it with 3rd party (as in not-HP non-genuine aftermarket) ink cartridges.

At least that printer was made before 2016 so can run such cartridges though with a "can't guarantee quality" warning message, since the firmware makes it so you can't align them. Later models will refuse to print or even brick the printer with unauthorized cartridges, a feature called HP Dynamic Security ostensibly for protecting your safety (and of course just incidentally, their wallet).

Don't do business with companies like this. There have been too many times I've had to transplant DRM chips in genuine HP cartridges with one from an empty, because the chip in a brand new cartridge was no good. When H&P were still alive, HP products were the best in the world and seriously overbuilt to last for decades (yes, I am still using their 1990s printers that originally came with drivers on floppy disk... with Windows 11). Those days are long gone.
