A:AnswerHi David. The HP Envy Photo 7855 cannot scan 11x14". It can scan 8.5x14 using the automatic document feeder. The largest width it can scan is 8.5".
A:AnswerIf you have an older wireless router, it may be time to upgrade. The newer routers have a longer range and they handle more devices. If you are still having issues, visit https://support.hp.com
A:AnswerNo, the Envy Photo 7855 does not. The OfficeJet Pro 9015 can auto duplex scan/copy in 2 passes (it flips the paper over automatically) and the OfficeJet Pro 9025 has single pass duplex scanning/copying.
A:AnswerIf you're concerned about using archival materials for printing and selling artwork I'd recommend using a different printer that uses pigment based ink and this printer uses mostly dye based ink. Pigment based ink is more fully saturated with color and will be more archival. It's more expensive but worth it if you're serious about selling someone art that will last.
