ABSTRACT:
An apparatus for determining the print region for individual sheets of paper for use in a printer is provided. A paper sheet feeder for feeding the individual sheets of paper is supported on the printer. A sensor detects the presence of a sheet of paper fed by the paper sheet feeder. A microprocessor measures the length of the individual sheet of paper based upon the detection from the detector and provides a measurement value. The microprocessor computes the size of a possible print region of each sheet paper based upon this measurement value and displays the size of a possible print region on a display. Memory associated with the printer stores the size of the possible print region for setting the internal condition of the printer upon the introduction of power to the printer.
