    Have you considered Point Of Sale (POS) printers in UPDF?
    I am looking at a technical reference for one right now and it has an
    interesting feature.
    There are two rolls of paper in this printer and you can print to them in
    the following
         - Print only on the left roll. This is torn off and given to the
         - Print on the left roll and print a duplicate to the right roll.
    This roll is called a "journal" roll.
         - Image the form size to be twice the size of the roll. Any print
    data that does not fit onto
              the left roll is overflowed and printed on the right roll. This
    way you can print two
              different things at one time.

    Also, the roll paper is 228 pels wide at 90 dpi. This translates into a
    form size of 2.5333333333333333333333333333333... inches. The length of
    the form can be between 1/72 of an inch to an infinite length.
