The HP Smart Tank Plus 651 is a cartridge-free inkjet all-in-one that prints, scans, copies and faxes, with a 35-sheet automatic document feeder on top. It uses refillable ink tanks fed from bottles, and HP includes enough ink in the box for a long run of pages. Dual-band Wi-Fi and the HP Smart app handle setup and mobile printing. It suits home offices and schoolwork where volume is steady and running costs matter more than speed; compared with cartridge all-in-ones it trades a higher upfront outlay for far cheaper pages, and it is slower than laser rivals.
