Chapter 1
Overview
Check the followings for HTTPS communication.
Prepare a certificate and secret key for the server, then register them to the printer.
Self-signed certificates can be created by TM-DT series devices with version 4.0 or later of the TM-DT
software, TM-i series devices, and TM-T88VI devices. For instructions on how to create a self-signed
certificate, see Technical Reference Guide of the printer. Name and common name of the self-signed
certificate are the printer’s IP address.
Common name of the server certificate and the host name of the printer must be the same. Otherwise,
HTTPS communication will fail with an error.
Embed a CA (certificate authority) certificate, which is used to authenticate the CA signature on the server
certificate, in your program. Otherwise, HTTPS communication will fail with an error.
When creating an iOS application, make sure to satisfy the requirements of ATS (App Transport Security).
Comply with requirements for HTTPS communication of your application development environment.
To send print data to the printer from an application on a HTTPS Web site, make sure to use HTTPS instead
of HTTP to communicate with the printer. Otherwise, the communication will fail with an error.
