Transmit printer ID, remote diagnostics extension

ASCII	GS I @ n
Hexadecimal	1D 49 40 n
Decimal	29 73 64 n
Values of n:	Refer to table
Range of n:	32–255 (not all defined, but reserved)

Eighteen remote diagnostic items are defined in the following table: eight printer ID items and ten printer tally items. A group of four remote diagnostic functions is assigned to each diagnostic item. Most of the diagnostic items are maintained in non-volatile memory (NVRAM), but some are maintained in read-only memory (ROM).

The first item group in the table includes an example of data to send and to receive. Data sent from the host to write to NVRAM must contain all digits required by the remote diagnostic item. All data must be ASCII. The printer returns all ASCII data. It is preceded by the parameter n to identify the diagnostic item and is followed by a carriage return (0D) to signify the end of the data.

Each returned message is defined as: n + data + <CR>

The command performs the remote diagnostic function specified by n as described in the following table.

Value of n

ASCII	Hex	Dec	Remote diagnostic item	Function
Space	20	32	Serial #, 10 digit ASCII	Write to NVRAM Example, send 14 bytes to printer:
				GS I @ 0x20 1234567890
!	21	33	Serial #	Write to NVRAM, and print on receipt to verify
				Example, send 14 bytes to printer:
				GS I @ ! 1234567890 This will print on receipt:
				Serial # written: 1234567890
#	23	35	Serial #	Return Serial #, preceded by n to identify Printer
				returns 12 bytes in above example: #1234567890<CR>
$	24	36	Class/model #, 15 digit ASCII	Write to NVRAM
%	25	37	Class/model #	Write to NVRAM, and print on receipt to verify
‘	27	39	Class/model #	Return Class/model #, returns 17 bytes
+	2B	43	Boot firmware part #, 12 digit ASCII	Return Boot firmware part #, returns 14 bytes
/	2F	47	Boot firmware CRC, 4 digit ASCII	Return Boot firmware CRC, returns 6 bytes
3	33	51	Flash firmware part #, 12 digit ASCII	Return Flash firmware part #, returns 14 bytes
7	37	55	Flash firmware CRC, 4 digit ASCII	Return Flash firmware CRC, returns 6 bytes
Ç	80	128	Receipt lines tally,	Write to NVRAM Example, send 12 bytes to printer:
			8 digit ASCII numeric,	GS I @ Ç00010000 To set receipt lines tally to 10,000
			max 99,999,999
ü	81	129	Receipt lines tally	Write to NVRAM, and print on receipt to verify
				Example, send 12 bytes to printer:
				GS I @ ü00010000 This will print on receipt:
				Receipt tally written: 10,000
é	82	130	Receipt lines tally	Clear receipt lines tally to 0
â	83	131	Receipt lines tally	Return receipt lines tally, preceded by n to identify
				Printer returns 10 bytes in above example:
				â00010000<CR>
ä	84	132	Knife cut tally, 8 digit ASCII numeric,	Write to NVRAM
			max 99,999,999
à	85	133	Knife cut tally	Write to NVRAM, and print on receipt to verify
