Printing Process
1
TM printers with SDP support sends a request (print request) to the Web server. This
request is sent periodically at the set timing.
2
When data to be printed exists, the Web server application creates an XML-format
response containing the data to be printed, and returns it to the TM printers with
SDP support.
When no data to be printed exists, an empty response is returned.
3
TM printers with SDP support prints the data to the specified printer.
4
TM printers with SDP support sends a printing result request (printing result). *
5
Upon receipt of the printing result, the application performs the required process.
The Web server automatically responds with an empty response.
*
: If the spooler is enabled in the TM printers with SDP support, a request (print result) is returned upon receipt
of a response (print request).
(For TM-i Firmware Ver.4.1 or later of the TM-i series. For TM-DT Software Ver.3.0 or later of the TM-DT series.
For TM-T88VI)
The printing flow is as follows:
1 : HTTP Request (Print request)
2.2 : HTTP Response (Print request)
6.2 : HTTP Response (Printing result)
5 : HTTP Request (Printing result)
