Performs the remote diagnostic function specified by
n.
Eighteen remote diagnostic items are defined: 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 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.
