Hundred dollars for the printer, probably 20 cents a day for the consumables (paper, toner, electricity). The paper is recyclable. At one page a day, I would guess lifetime will be dominated by mechanical lubrication or degradation of capacitors, dust clogs, etc.

Hundred dollars for the printer, I think Zou are absolutely over spending here. Electricity can be saved by having shutoff and turn on with a timer.

That could be actually nice!
