With my previous ET-2500, it didn’t have edge guides which centred all the paper. I was able to set it so that I could print greetings cards with an A6 image on one half of A5 paper, so that I could fold the A5 into an A6 greeting card. The ET-2720 centres the paper so that this procedure isn’t possible. How can I over come the centring so that I can print on just one half of an A5 sheet?
