First thing I did not purchase HP 962XL. I purchase HP910 individual (4). I am not pleased because the price is too high for the amount of ink. You cannot print 200 sheets before your ink is out. I am search for other carriers.
I'm still using the ink that came with the new printer (amazed it's lasted this long) so I'm unsure how long this new ink will last. Based on my last printer the xl ink lasted close to a year and if these last that long I'll be pretty happy.
