• With a parallel interface printer, data (printer ID, printer information) sent with this command is
temporarily stored in the printer send buffer like other transmitted data (except ASB). When the host
goes into reverse mode, the printer then sends the data sequentially from the beginning of the send
buffer. Send buffer capacity is 99 bytes. Data exceeding this amount is lost; therefore, when using this
command, promptly change into reverse mode to start the data receive process.
[Notes for printer ID]
■Each printer ID is composed of 1 byte of data (when 1 ≤
n
≤ 3, 49 ≤
n
≤ 51).
■Printer model ID differs, depending on the printer model (when
n
= 1, 49).
■Transmits specified printer information, as follows:
• For the parallel interface model, bit2 is “DM-D (customer display) is not installed.”
■There is one to one correspondence between the version ID and the firmware version. The details differ,
depending on the printer models.
