Have you used Instax SP-3 printer with X-E3?

If yes, I've got a couple of questions.

1. Is connecting the camera to the printer quick, easy, and reliable, or is it like connecting to Camera Remote, which is slow, painful, and unreliable?
2. If I set the crop mode on the camera to square and transfer the photo to the printer, is it the square crop I see in the viewfinder and image review the same as what the Instax printer uses?

Thanks.
