Sorry if this appears a completely dim question but I have no experience whatsoever of roll paper holders. I've been offered one of these by the vendor who sold me the printer for less than 40% normal price. I've had a roll sitting around for a while for occasional longer prints but I planned to just cut a length from the roll and reverse the curl by wrapping round a plastic tube. Where do you cut the paper on a roll paper feeder? - if it's where the finished print emerges from the printer, that's wasting an awful lot of paper.
