HP HPIZ3X450 Sprocket 3x4 Zink Sticky Photo Paper 50-Pack

The HP HPIZ3X450 Sprocket Zink Photo Paper is a 50-pack of 3.5" x 4.25" sheets designed exclusively for the HP Sprocket 3x4 Photo Printer. Using Zink (Zero Ink) technology, each sheet contains embedded dye crystals that are activated by the printer's heat elements, producing full-color photos without any ink cartridges, ribbons, or toner. This makes the printing process clean, compact, and remarkably simple—just load the paper and print directly from the HP Sprocket app on a smartphone.

Each sheet features a peel-and-stick adhesive backing, turning every print into an instant sticker that can be applied to scrapbooks, journals, walls, laptop covers, or greeting cards. The premium glossy finish is engineered to be smudge-proof, waterproof, and tear-resistant, so photos maintain their appearance through handling, humidity, and everyday use. At 3.5" x 4.25", the prints are noticeably larger than those from the original HP Sprocket, allowing for more detail and visual impact in each image. For HP Sprocket 3x4 owners looking for a reliable, high-quantity refill that delivers vibrant, durable, stick-anywhere photos, this 50-pack provides a practical and creative solution.
