Digest Access Authentication

This section describes the flow and settings for carrying out Digest access authentication with the web
server.
TM Intelligent Printer
For Digest access authentication, the printer sends a dummy HTTP request before sending a print-related
request to the server. The server returns a response with HTTP status code "401 Unauthorized". The printer
sends a print-related request containing the user ID and password. The server carries out the Digest access
authentication process. Once authenticated, the server continues to carry out the print-related process.

Digest Access Authentication Settings

Digest access authentication requires settings for the TM intelligence printer and the server.
TM Intelligent Printer
Use EPSON TMNet WebConfig of TM-i/TM-DT to set your user ID and password required for Digest access
authentication.
For details, see "Server Direct Print Settings" for individual TM intelligent printers.
