I'm on a Mac OS10.9 and printing with an Epson 4880 on a 10" roll of luster paper. I'm trying to print a 9" wide image centered on 8x10 paper with a 1/2" border on all sides (from 8x10 original proportions - so approx 7x9" image). The printer is cutting the paper to 10" wide x 9.25" size - it is centering the image on this, but I want my final cut page to be 8x10 so the image has a fairly equal 1/2" border on all sides without extra trimming required. I'm getting my 1/2" border on the width but just over 1" border on the height.
I set up a custom 8x10" size under page setup, and zero out all the margins in this dialog. I've actually tried both 10 wide by 8 high, and 8 wide by 10 high (w/ reversing the orientation) Then under printer settings in the Epson driver, I select the simple "roll paper" (not banner , borderless, etc.). I've In LR print module, I'm using a 7x9" cell and zero out all the margins there.
Any suggestions? Thanks.
