Cognitive Solutions A799 manual Recognizing data from the printer, Batch mode response

Recognizing data from the printer

An application sending various real time and non-real time commands to which the printer responds can determine which command a response belongs to by the table below.

Responses to transmit peripheral device status (1B 75) and transmit paper sensor status (1B 76) are non-real time responses and will arrive in the order in which they were solicited.

Batch mode response			Response recognized by:
ASCII	HEX
ECS u 0	1B 75 0		0	0	0	0	0	0	x	x	Binary
ESC v	1B 76		0	x	x	0	0	x	x	x	Binary

Unsolicited status mode (USM)			Response recognized by:

Bar codes

These commands format and print bar codes and are described in order of their hexadecimal codes.

These commands describe operation for 80mm paper. If the printer supports 82.5mm paper, the dot spacing is the same but there are 640 printable dots rather than the 576 printable dots on 80mm paper.

Select printing position of HRI characters

ASCII	GS H n
Hexadecimal	1D 48 n
Decimal	29 72 n
Value of n:	Printing position
	0	= Not printed
	1	= Above the bar code
	2	= Below the bar code
	3	= Both above and below the bar code
Default:	0	(Not printed)

Prints HRI (human readable interface) characters above or below the bar code.
