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.

Function
Write to NVRAM Example, send 14 bytes to printer:
GS I @ 0x20 1234567890
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
Return Serial #, preceded by n to identify Printer
returns 12 bytes in above example: #1234567890<CR>
Write to NVRAM
Write to NVRAM, and print on receipt to verify
Return Class/model #, returns 17 bytes
Return Boot firmware part #, returns 14 bytes
Return Boot firmware CRC, returns 6 bytes
Return Flash firmware part #, returns 14 bytes
Return Flash firmware CRC, returns 6 bytes
Write to NVRAM Example, send 12 bytes to printer:
GS I @ Ç00010000 To set receipt lines tally to 10,000
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
Clear receipt lines tally to 0
Return receipt lines tally, preceded by n to identify
Printer returns 10 bytes in above example:
