Black borders cropped and not even on an EPSON P600

Hi all,

I am new to this forum, looks amazing. Hi to everybody.

I tried to look around for my printing problem but I cant solve it. It starts to drive me crazy. I am looking for help and advice.

I am trying to print a 4x6 with a black borders.

If I define my page set up as:
1. 4x6 sheet borderless (not processed shoot), Zoom to fit activate or not, no margin but with a black stroke border = Print as presented in file 01, the black borders are cropped but most annoying one is shallower...
