3.3.3. Raw Mode Print (TCP #9100) Specifications
This product provides Raw Mode Print communications that is used as a listen port for the Port: 9100,
as a printing mechanism running under the TCP/IP environment. With Raw Mode Print, all data that
flows between TCP sessions is considered data handled between the printer and PC. Bi-directional
data transmission is thus performed.

• The maximum number of sessions accepted on the Port: 9100 is settable using the
following setting items.
• 9100 Multi-session: Enable: 8; 9100 Multi-session: Disable: 1 A rejection of
acceptance (TCP reset) is issued from the product to all PCs that could not establish
connection if there is no request for connection of more than the maximum number of
sessions accepted.
• Data traveling from the printer in the direction of the PC is printer status (ASB status)
information obtained via the serial RS-232C.
• Only when there is a change in the status is status data from the printer obtained by an
interruption from the printer and sent to the PC.
• The end of 1 data is considered to be established at the cut off of a TCP session (TCP FIN,
TCP RST • TCP Session Timeout). Special communication procedures are not
performed on the printer at this time. In the event that special control is necessary, such
as stopping the printer, that is performed on the PC.
