A:AnswerIt is a two cartridge printer so if the tricolor ink runs low on a single color before the other two run out you would need to replace the entire tricolor cartridge.
A:AnswerYes, it has wifi. I just purchased this printer and I have printed several documents from my laptop via wifi. I have not tried from my phone yet, but according to the instructions that feature is available.
A:AnswerNo, you do not need a PC to setup the printer. You can set up the printer using the HP Smart App on your iPad, iPhone or any other mobile device.
A:AnswerNo, you cannot scan to a USB thumb drive on this printer. I would recommend looking at the HP Envy Photo 7855, Officejet Pro 8035, 9015 or 9025 printers, which would have the front USB port so that you can scan to a USB thumb drive.
A:AnswerYes, it scans multiple pages in one scan. The top has an automatic document feeder that flips up. You don’t see it’s there in the picture. Very slick.
