A:AnswerThe power button is located on the back side of the printer beside the USB port. Here is a link to the User Guide. There is a diagram that shows it's position on page 3:

A:AnswerYou would need a "USB Printer cable". You'll need to know about how far apart the printer and computer will be, and get one a little longer than the distance between them. If you've still got a USB printer cable from some time before, that cable will work just fine.
A:AnswerDid you ever find a printer that worked? I just got my XB7, and what a surprise, my 4 year old Officejet 7740 does not connect to it. Out of 42 devices on my network, I have one Leviton light switch, one Phyn Plus water leak detection module, and the HP printer that don't work.
A:AnswerHello there! That's a great question! The HP ENVY Pro 6055's setup cartridges have a yield of ~120 pages for black, and ~75 pages for the tri-color. I would highly recommend purchasing at least a HP 67 black cartridge so you do not run out of ink during an important print job. Thank you for your interest in the HP ENVY 6055 and have a great one!
