Description ESC c 3 n selects whether to output paper-end signals or not to a parallel
interface. The default setting is n=15. The paper roll low, paper roll end, and
validation sensors can be selected. When the sensors are selected to output
signals and any sensor detects a paper-end, the paper-end signal is output.
When all sensors are disabled, and a paper out is detected, status is always a
paper present. The paper roll low sensor is enabled when either bit 0 or bit 1 or
both is on. The paper roll end sensor is enabled when either 2 or 3 or both bits is
on. The validation sensor is enabled when either 6 or 7 or both bits are on. This
command is enabled only with a parallel interface and is ignored with a serial
interface.
The paper sensor(s) used to output paper-end signals are selected by using n as
follows:
Bit Off/On Hex Decimal Function
0 Off 00 0 Paper roll low sensor disabled.
On 01 1 Paper roll low sensor enabled.
1 Off 00 0 Paper roll low sensor disabled
On 04 2 Paper roll low sensor enabled.
2 Off 00 0 Paper roll end sensor disabled.
On 04 4 Paper roll end sensor enabled.
3 Off 00 0 Paper roll end sensor disabled.
On 08 8 Paper roll end sensor enabled.
