Amateur user needs help with rotation problem

Hi, I have long struggled with some .jpgs printing out rotated. I have browsed past solutions involving Ghostscript setting boxes and registry key edits. As a total novice, I would be very grateful for a step-by-step guide to fixing this problem. I have version 4.04 and cannot see the settings screen a previous solution showed, nor find orientation settings in my settings menu.

Thanks for any help!
