IPP (Internet Printing Protocol)
IPP is an industry standard protocol for printing, as well as managing print jobs and media
sizes, and supports authentication and encryption, making it a capable and secure printing
solution. IPP is an IP-based protocol and can be used locally or over the internet.
Note: To configure IPP for secure/encrypted printing, specify a user name, password, and
digest authentication (for Windows only). Every client that tries to print to the printer over IPP
must enter this information. The user name and password are sent in plain text to the printer. If
you specify digest authentication, the password is secured before it is sent to the printer.
To change IPP settings:
1. Launch your web browser.
2. Enter your printer’s IP address in the browser’s Address field.
3. Click Properties.
4. Select the Protocols folder on the left navigation panel.
