[This review was collected as part of a promotion.] I'm so glad HP still sells this model ink for my older model 270 HP printer. No wireless, but it's still working after 21 years. This ink is fast drying & there is no lag time for it to"dry" like some of the newer ink jets have. Never any smudges or clumping with this ink. I wish HP sent the recycling bags out like they used to last year, so I can properly dispose of my used cartridges.
