Would someone who uses this model (Epson R1800) (or similar) with roll paper please tell me how one cuts the print from the roll? Does it require you to feed additional paper through so that you can cut it with scissors? How much paper does one waste in doing so? I like the idea of roll paper, but since this printer doesn't automatically cut the paper as some of the higher end printers do, I need some input from those that have used it.
