The **HP ENVY Pro 6455** is a wireless all-in-one inkjet printer designed for printing, scanning, copying, and faxing. It is **Instant Ink Ready**, meaning it can automatically order ink and deliver it to your door, potentially saving up to 50% on ink costs through HP’s subscription service[1].

Key features include:
– **Print speed:** About 7 pages per minute in color and 10 pages per minute in black and white; text print quality is good but slightly slower than average inkjets[1][2].
– **Print technology:** Uses inkjet with HP 67 cartridges, including standard and high-yield ink options[1].
– **Scanner:** Flatbed scanner with up to 1200 x 1200 dpi resolution and an Automatic Document Feeder (ADF) for batch scanning or copying up to letter size[1][2][3].
– **Copy and fax:** Supports copying (fair quality compared to other all-in-ones) and integrated fax capabilities[1][2].
– **Connectivity:** Wireless (Wi-Fi) and USB support; no display screen on the printer[2].
– **Paper capacity:** Main tray holds 100 sheets; output tray holds 25 sheets[1][2].
– **Auto duplex printing:** Supports automatic two-sided printing with no loss of print quality[2].
– **Energy efficient:** ENERGY STAR certified[1][4].

In terms of use:
– Printing photos yields very good results but it does **not** support borderless photo printing[2].
– The scanner can handle black-and-white scans at around 7 pages per minute and color scans at about 3 pages per minute; it does not automatically scan both sides of a document, requiring manual flipping for double-sided scanning[3].
– Copying is relatively basic but straightforward, with front buttons for easy copy quantity selection[3].

Overall, the HP ENVY Pro 6455 is a mid-range home or small office printer that balances good photo and document quality, wireless convenience, and ink subscription benefits with modest speeds and no touchscreen interface[1][2][3].
