Epson Secure Printing: what it blocks and how to turn it off
Symptom: the app says "Secure Printing is on. Turn it off on the printer, then try again." Or a brand-new Epson is found on the network, the test page appears to send, and nothing comes out — no error, no light, and the printer's own status page says it's available. Panel self-tests print fine.
Why it happens
Epson TM-series printers built for the EU and UK since 1 August 2025 ship with Secure Printing enabled, to meet the EU's Radio Equipment Directive. While it's on, the printer accepts jobs sent over the old unencrypted channels and then silently discards them.
| Channel | Secure Printing on | off |
|---|---|---|
| Raw TCP, port 9100 | Accepted, then discarded | Prints |
| ePOS-Print over HTTP (80, 8008) | Not served | Prints |
| ePOS-Print over HTTPS (443, 8043) | Prints | Prints |
Units sold outside the EU can carry the same firmware. If a new Epson anywhere shows this symptom, check the setting.
Turn it off
You need the printer's admin password. On recent models that's the serial number on the label underneath the printer; older models used epson.
- Find the printer's address — it's on the status sheet (open the roll cover, hold Feed).
- Open
https://printer-ipin a browser and accept the certificate warning. - Administrator Login, then Print → Secure Printing.
- Set it to Disable and confirm.
- Unplug the printer for ten seconds and plug it back in.
- Print the test page again.
Epson resets the security configuration to its defaults on firmware update. If a printer that worked for months stops right after an update, repeat these steps.
While you're in there, set your own admin password — anyone on the same network can reach an open receipt printer.
