Yes, curled paper is not your friend. As fft81 said you need a tube to decurl the paper. I made one "device" out of PVC-drain pipe, 3" it was. But I used a bed sheet from Ikea and cut it to the width of the tube, lenght 3 feet. I made a slit to the pipe and slid the bed sheet to it. Just mangled the pre cut roll sheet diagonally twice opposite corners, takes about 30 seconds and you can print. The paper must be tight between the cloth and the pipe. There are same kind of derollers for sale, but I'm sort of DIY person.
