n n Roll paper end detector
Located in the roll paper path. This detector detects paper out. However, roll

Detectors and printing
The printer will either stop or continue printing according to the ESC c 4 setting
when a paper-end is detected. The roll paper near-end detector and roll paper
end detector are both available. (Refer to 5-2 The PAPER LED)
When stop printing mode is selected, the printer automatically goes off-line when
the roll paper near-end detector or the roll paper end detector detects paper out.
Therefore, the printer should go on-line after setting the paper to restart printing.
Switching on-line is executed by closing the printer cover.
