I have Epson SC-P800 printer and I use LR for printing. I print on Hahnemuhle 10x15 photo cards which are 100x150mm. To crop image in LR I use 4x6 aspect ratio which is the same as 10x15 (1:1.5). Then I use custom size in Print module: Paper Size: Width: 100mm Height: 150mm and Non-printable area is 0 for each of 4 sides (screenshot is attached). In Layout I use 0mm margins and Height/Width = 150mm/100mm
Driver setting are default.
When printed, image cropped approx 3-5mm by each side.
I am attaching original image and image of the print and hopefully you'll be able to see what I mean.
How can this be fixed?
P.S.updating this question with more relevant screenshot of image in Print module - you can see there that printed image is cropped.
I decided to print on more standard paper 4x6 inches or 102x152mm: 1) first I cropped image to 4x6 ratio: 2) then I selected 4x6 Sheet Feeder Borderless Auto Expand in Print module: as you see, there is author's signature is visible on the bottom and there is space between image border and dog's tail. 3) result on 102x152 paper is cropped (not space to the right of dog's tail and no author's signature):
So, I assume that there is no way to correctly print images on small papers when cropping really matters on Epson SC-P800.
