A:AnswerYou need a device to install the software on (a PC or Mac) that will do the wireless setup.

A:AnswerDid not measure it with a wattmeter but it actually needs a lot of peak power - when it starts up, my lights dim down for the moment. That's why I can imagine that it takes around 2kW of peak power at start up (normal wattage when printing is around 350-450W).
A:AnswerThis printer does NOT print any envelopes nor post cards. The sign inside tray clearly says NO ENVELOPES. Attempted to print on post cards but every single time it jams. So the answer is STRICTLY NO ENVELOPES / POST CARDS can be printed with this printer.
A:AnswerYou can print in black. Just select that when choosing to print or copy.
I do not know how long the cartridge lasts without use. I print often.
