HP Sprocket

HP Sprocket. The HP Sprocket is a line of portable, wireless photo printers designed and marketed by HP Inc. Primarily utilizing ZINK Technology (Zero Ink), these compact devices allow users to print small-format photographs directly from a smartphone or tablet computer. The product line emphasizes social sharing and physical keepsake creation from digital images stored on platforms like Instagram and Facebook.

Overview

The Sprocket series was introduced by HP Inc. as part of its expansion into the personal and mobile printing market. It directly competes with similar portable photo printers from companies like Canon with its IVY mini printer and the Polaroid Lab. The core technology enabling its inkless operation is licensed from ZINK Holdings, which uses embedded dye crystals in specialized paper. This approach aligns with HP Inc.'s broader strategy in the instant printing segment, complementing its larger Sprocket Studio format printers.

Features

Key features of HP Sprocket printers include their pocket-sized, battery-powered design for true portability. They employ the ZINK Technology process, where heat from the printer activates color-forming crystals in the ZINK Paper, eliminating the need for traditional ink cartridges or toner. Most models include a built-in rechargeable battery and feature a simple interface often consisting of a single power button. The printers are designed to produce durable, sticky-backed prints suitable for use in scrapbooking, journaling, or as instant adhesive decorations.

Models and specifications

The product line has seen several iterations since its launch. Early models, such as the original HP Sprocket, established the basic form factor and Bluetooth connectivity. Subsequent releases like the HP Sprocket Plus offered slightly larger 2.3 x 3.4-inch prints compared to the standard 2.1 x 3.4-inch credit card size. Later models, including the HP Sprocket Select and HP Sprocket 2nd Edition, incorporated improved print speed and image processing capabilities. All models specify print resolution in terms of dots per inch (dpi) and are compatible exclusively with the proprietary, dye-based ZINK Paper.

Connectivity and software

Connectivity is primarily established via Bluetooth Low Energy or direct Wi-Fi connection to a mobile device. The companion application, HP Sprocket App (available on iOS and Android), is essential for operation. This software provides tools for editing photos, applying filters, adding emoji and text overlays, and creating collage layouts. The app integrates directly with mobile device gallery storage and social media platforms, allowing for printing from Snapchat and WhatsApp. Some models also support Near-field communication (NFC) for tap-to-print functionality.

Use cases and applications

Typical use cases center around social and creative activities. Users frequently employ the printer for creating physical photo booth souvenirs at events like weddings and birthday parties. It is popular for crafting personalized bullet journal entries, planners, and photo album pages. The adhesive backing enables the decoration of items like laptop computers, water bottles, and school supplies. It also sees use in educational settings for project-based learning activities and in small retail environments for on-demand product label printing.

Reception and reviews

Critical reception from technology reviewers and publications like CNET and TechRadar has often highlighted the convenience and fun factor of the Sprocket, while noting the ongoing cost of ZINK Paper as a significant consideration. Reviews frequently compare the print quality and color saturation to that of drugstore photofinishing, suitable for casual sharing rather than archival purposes. The product has been recognized with industry awards, including the 2017 CES Innovation Award in the Digital Imaging category. Market analysis from firms like IDC often cites the Sprocket line as a key player in the niche but growing mobile printer segment.
