A:AnswerYes. Just do a search for the model number asking if it supports AirPrint and a list of instructions will show up for connection to a PC or Mac.
A:AnswerYes, if you connect your computer to the printer with an ethernet cable during initial setup you can print from the computer. There are YouTube videos showing how to connect an ethernet cable to a smartphone.
A:AnswerBlack and all color starter cartridges come with the printer. I don't know how long they last, so I bought regular cartridges too at the same time.
