Using roll paper ... I'm wondering what is the 'default' margin for the z3100 and presumably the z3200 as well. Mine has a 4mm left margin and a 6mm right margin. I'm guessing that this isn't normal.
It's easy enough to kludge the left margin, so that it prints 5mm, but I can't get the right margin to print less than 6mm. Even using the HP Print Preview to move the print 1mm to the right doesn't work, because it just cuts off 1mm of the image and still leaves a 6mm margin. Both the top and bottom print 5mm, which is what I suppose they're all supposed to be.
Very confusingly, this doesn't always happen. I've wondered if there can be a problem with paper load, that could be throwing something out? Is there an adjustment inside the machine, that can be made to rectify this?
