I have been taking colour Print since a month, including ones on photo paper. Photo print turns very dark so I forcefully make them bright in software before printing. Ink usage seems pretty optimum. It give more time when printer is idle due to ink getting replenished. The main problem is doesn't support Linux, no Linux driver and neither it supports cups print server. ( this is very important to me)
And no you can't print from Android using otg cable since there's no driver available. It doesn't work with multiple USB devices. It is not a quality product. Save your money.
