I'm a big fan and endorser of HP printers and products. They are work horses and after years of experience don't trust anything but HP ink. It's pricey but you get what you pay for.
I purchased all XL cartridges for my HP Officejet Pro 9015e that requires the 962 cartridges. The XL color cartridges did not work. It gives me an error message. I don't know if my printer is going out or if the cartridges don't fit correctly. I use the Black XL all the time but had not tried the color XL because of the expense of buying all XL at the same time. I took the plunge and it didn't work.
