The HP ENVY 6455e is a wireless all-in-one inkjet printer that can **print, scan, and copy**, but it does **not have a built-in fax function** (though faxes can be sent using the HP Smart app)[1][2]. It features **automatic two-sided (duplex) printing, an automatic document feeder (ADF) for up to 35 pages, and wireless connectivity via Wi-Fi 802.11b/g/n**[1][2][5].
The printer uses HP 67 series ink cartridges, including standard and XL sizes:
– HP 67 black cartridge: ~120 pages
– HP 67 tri-color cartridge: ~100 pages
– HP 67XL black cartridge: ~240 pages
– HP 67XL tri-color cartridge: ~200 pages
– HP 67XXL black cartridge: ~400 pages
– HP 67XXL tri-color cartridge: ~330 pages[1]
It comes with HP+ Smart Printing System features that include automatic updates and cloud-enabled printing from almost anywhere, but setup requires the HP Smart app, which some users find inconvenient. The printer has a power-saving sleep mode that has been reported to cause connection or printing delays unless the device is power cycled[3].
Physical specifications include dimensions about 17 x 14 x 7 inches, weight around 13.5 pounds, and an ENERGY STAR® certification for energy efficiency[2].
In summary, the HP ENVY 6455e is suitable for home or small office use requiring wireless multifunction capabilities and supports automatic duplex and document feeder functions but lacks native fax hardware. Users should be aware of HP Smart app dependency and potential sleep mode quirks reported by some customers[1][2][3].
