Cognitive Solutions A799 Initialize printer, Select paper sensors to output paper-end signals

Revision D 12/09Chapter 4: Programming Commands  37

Initialize printer

ASCII	ESC @
Hexadecimal	1B 40
Decimal	27 64
Default:	Character pitch:	15.6 CPI
	Column width:	44 characters
	Extra dot rows:	3
	Character set:	Code Page 437
	Printing position:	Column One

Clears the print line buffer and resets the printer to the default settings for the start-up configuration (refer to Default settings above).

Single-wide, single-high, non-rotated, and left-aligned characters are set, and user-defined characters or logo graphics are cleared. (Flash memory is not affected.) Tabs reset to default. Receipt selection state is selected.

Select paper sensors to output paper-end signals

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.

Bit	Position Hex		Decimal	Function

4, 5, 6, 7 –		–	–	Undefined
Range of n:		1–255
Default of n:		12

Specifies 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.
