Note: (1) The amount of remaining roll paper differs greatly depending on the type of roll paper.
Use these values only as guideline.
(2) If the sensor detects the Paper Near-End during printing, the printer stops only after it
has printed all the data that it has received in the reception buffer.
(3) Under the centronics interface specification, this Paper Near-End (PNE) detection is
valid only when Paper Near-End of the software switch is enabled. If PNE of the software
switch is set disabled, PNE detection is ignored.
Under the serial interface specification, PNE is always valid.
(4) If roll paper loosens too easily when its external diameter is becoming small, PNE may
not be detected correctly.
