The HP Smart Tank 670 is a versatile all-in-one multifunction printer designed to handle printing, scanning, and copying tasks in one device. It uses thermal inkjet technology with four integrated ink tanks—one black and three color—which allows for high-volume printing without the need for frequent cartridge replacements. You can expect print speeds of up to 12 images per minute for black documents and 7 ipm for color, while draft mode can reach up to 30 ppm for black text, making it efficient for those who need to produce a significant amount of paperwork quickly. This model simplifies your workflow with automatic duplex printing, saving you the trouble of flipping pages manually. The hardware is powered by an 800 MHz processor and 128 MB of memory, ensuring smooth operation when processing documents up to a resolution of 4800 x 1200 optimized dpi for color prints. For scanning and copying, it features a flatbed CIS scanner with an optical resolution of up to 1200 dpi, supporting various file formats like PDF and JPG. Connectivity is flexible, as the printer supports Wi-Fi, Bluetooth, USB, and Wi-Fi Direct, allowing you to print wirelessly from mobile devices via Apple AirPrint or Mopria. The white and grey chassis houses a 150-sheet input tray and an LCD display with smart-guided buttons for easier navigation. Weighing about 6.3 kg and measuring 427.5 x 364 x 198.6 mm, it fits comfortably on a desk for home office use or small business environments where monthly volumes typically range between 400 and 800 pages.
