I know when I open the package of HP ink & place the cartridge in my printer I can always depend on the alignment page printing perfectly...& every print request I send thereafter.
Staples sent out a 10.00 coupon but of course when I went to the store to purchase the HP Ink I could not apply so I purchased a 9.00 ream of paper and used the coupon. Somehow not sure this was a great deal but oh well!!! :)
