Hello all! I'm new here on this forum and I am going crazy over this used Vivitar slide printer that I just got. I feel like the biggest idiot, but this thing didn't come with a user guide and I cannot for the life of figure out how to load the dang thing. Am I missing something or what?? I can't fina manual anywhere online, even if I wanted to buy one...what it up?? Can someone help me out?? Thanks!!!!!
