(not all defined but reserved)

Preforms the remote diagnostic function specified by n.

Eighteen remote diagnostic items are defined: eight printer ID items and ten printer tally items. Most of the diagnostic items are maintained in non-volatile memory (NVRAM), but some are maintained in read-only memory (ROM).

The table that follows describes the variables.

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.

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