Dont buy if it not standard one. You may destroy you printer when you try to save some money..

Excellent. Such good cartridges

The XL versions of the HP970 cartridges offer about 3x the printing capacity as the standard cartridges, at a price premium more like 1.5x-2x, so the 970/971 XL cartridges are a no-brainer from my perspective.

It prints a lot of pages.

It arrived promptly, and it was exactly as depicted.
