A:AnswerI did print some 4 x 6 pictures on generic photo paper, and there was a little bit of smearing where I touched. Not sure if this would still be a problem if using better paper. It's all I had on hand. Picture quality was pretty good. And even with this printer being just a little slower in the number of pages it prints, it still came out in pretty good time. I would just maybe give it a little time before touching the printed area right away. But I've had that happen with my last printer as well.
A:AnswerMy husband's laptop does print to this printer, so yours should work, too, on wi-fi, I would assume bluetooth as well. There is a USB port on the front of the printer, just under the power switch, on the left of the paper tray.
A:AnswerThe paper tray only comes out about 2.5" further than the tray, and does not affect the printing. It is just enough to stop the papers from falling to the floor/desktop. Operation not affected whether in or out.
