Clears the print line buffer and resets the printer to the default settings for the start-up conguration (refer to Default settings
above).
Single-wide, single-high, non-rotated, and left-aligned characters are set, and user-dened characters or logo graphics are

ASCII ESC c 3 n
Hexadecimal 1B 63 33 n
Decimal 27 99 51 n
Value of n:
If either bit 0 or bit 1 is on, the paper roll near-end sensor is selected as the paper sensor outputting paper-end signals.
If either bit 2 or bit 3 is on, the paper roll-end sensor is selected as the paper sensor outputting paper-end signals.

Range of n: 1–255
Default of n: 12
Species the paper sensor to output a paper-end signal. Multiple sensors may be selected to signal when paper has run out.
When multiple sensors have been selected, anytime one of the sensors detects a paper-end, the paper end signal is output.
When this command is executed a sensor is switched. The paper-end signal switching is delayed depending on the receive
buffer state.
Exceptions
The command is ignored, except in parallel communications.
