The quality is excellent. My printer is an HP 4500 ENVY which requires both black and toner cartridges to operate. Unfortunately the cartidges seem now to be unavailable for purchase as a packaged pair and I am required to buy them individually at a quite high cost.
I’ve relied on the 61XL and 61 ink cartridges for many years, and they’ve always delivered excellent results. I really hope HP keeps them in stock because my printer/scanner still works perfectly, and I’d prefer not to replace it anytime soon. Highly dependable and well worth the cost.
