I print all my own covers on plain paper with an EpsonStylus CX7400. Because I just print from the default Windows Photo Viewer, the image is not quite the right size and I have a lot of white border (on UGC, DVD, and DS cases). But seeing as my collection is mine, all that matters is I like it. And I do.
1169 (for some reason, my NES games have not been entered in my database, so it is really over 2000) games, across 24 systems (including handhelds), gaming since 1986, but collection since 2001.
