Overview of Server Direct Print
Server Direct Print function enables the TM printers with SDP (Server Direct Print) support to obtain the print
data from the Web server and print the data. The Web server application performs printing by including
print data in the response to a print request from the TM printers with SDP support.
A TM printer with SDP support periodically sends a print request ((1) in the figure above) to the Web server.
The Web server application includes print data in the response ((2) in the figure above) to a print request
from the TM printers with SDP support. (When no print data exists, the Web server returns an empty
response.)
If print data for the TM printer is included in a response, the TM printers with SDP support controls the TM
printer in order to do the printing ((3) in the figure above).
The print data can be printed in the ePOS-Print XML format.
Upon receipt of a response of print data including print layout from the Web server application, the TM
printers with SDP support converts the ePOS-Print XML format into the print layout and prints it.
If the spooler is enabled in the TM printers with SDP support, print data can be saved in the spooler, which
allows an operation in which the next print request can be processed regardless of the printer status.
*1
In a system consisting of multiple printers, if forwarding is set in the TM printers with SDP support, print data
can be printed from another printer when it cannot be printed from the printer.
*1
It also allows you to control display of a Customer Display connected to the printer.

: TM-i series (TM-i Firmware Ver.4.0 or earlier) and TM-DT series (TM-DT Software Ver.2.6 or earlier) are not
supported.
