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.
