> But hell, you want to be able to print that photo on any old glossy paper you bought from someone, using a knock off cartridge, with any ink they shove into it. And it better come out looking like an Ansel Adams original, or damn it, HP screwed you as a consumer again!This is largely because other printers exist that can make acceptable prints on any glossy paper, using a knock-off or modded cartridge, with any ink bought from eBay. I have seen it with my own eyes.
Also, in my scenario, Grandparent is too technically inclined, takes all the photos, color-corrects all of them in Lightroom, and makes the prints on acid-free paper, using an inkjet that was custom-modded to have huge, refillable external reservoirs of archival-quality pigments before Epson EcoTank was even a thing. He guarantees color stability for 100 years. His cost per print is less than using an HP printer with HP ink cartridges. And some of his art photos are better than Ansel Adams prints, in my opinion.
For the rest of us, who take crap photos, we just go online to upload, print, and ship from a photo printing business--like Shutterfly, to name just one.
Don't coddle your parents. Drag them kicking and screaming into the 21st century, and make them administer the family photo-sharing web page, so their brains won't rot in retirement, and so Facebook won't get their meathooks into everybody. If you aren't willing to make photo printing into a full-blown hobby and do it properly, with a decent printer, you are far better off just paying a professional to do it for you, with a proper industrial photo printer. Get yourself a monochrome laser printer with a refillable toner cartridge, or the toner cartridge separate from the drum, so you can print your coupons and boarding passes and tabletop RPG character sheets, or whatever, and let HP color inkjets vanish into the hell of their own making.
