4.9 Paper End Detection Circuit

A paper sensor built in the printer detects whether there is the printing paper, so that the
printer will not be turned on when it has no paper.
When the printer has no paper, PAPER (Pin 7) of the CPU is turned to "HIGH." If printing is
under way, it will stop after printing that line, and output an error. When the paper is set,
printing is automatically resumed.
