That said, I don't actually see where these jumpers actually *are* (there is a suspicious looking cutout behind which is just empty space) so it's possible that it actually is parallel but still has the baud rate label for no good reason. I agree that the 20-pin interface would be more conducive to parallel rather than serial. - Josh

I've not seen thermal fax paper in office supply shops over here for about 10 years. Can you still find it in the UK (I've got a few HP thermal printers, including the 9866 on top of my 9830, that use it). Over here there were 2 common widths. 210mm and I think 216mm The latter was the one used in most American printers, the former was much easier to find. I obtained an HP printer (2761 or some such) that was designed to use the wider paper. All I could find in the local shop was the narrower stuff. It would use that provided the roll was in exactly the right place, otherwise the head would go off the edge of the paper and snag on the paper as it came back. So I grabbed some brass rod, cut a couple of thin slices, drilled a centre hole and carefully faced them off to be just the right thickness to put the roll where I needed it. Worked fine and I was happy -- unitl I went to another branch of the same office shop. They had the 216mm rolls. -tony

duell 10 printers, the right thin right -- You can still get it, but its becoming rarer... http://www.amazon.co.uk/Star-Thermal-Warning-Strip-W210mmxL15mx12-7mm/dp/B00 0J63NHW/ref=sr_1_1?s=officeproduct&ie=UTF8&qid=1417471012&sr=1-1&keywords=fa x+paper Dave G4UGM
