Hi SeydX,

I installed a new Epson ET-2756 printer in homebridge-print and got following error-message:

[4/9/2021, 3:41:29 PM] [PrinterPlatform] Epson ET-2756 Sensor: An error occured during adding filter services [4/9/2021, 3:41:29 PM] [PrinterPlatform] Error: Received unexpected response status 426 from the printer. at ClientRequest. (/homebridge/node_modules/homebridge-printer/node_modules/@sealsystems/ipp/lib/request.js:85:12) at Object.onceWrapper (events.js:422:26) at ClientRequest.emit (events.js:315:20) at HTTPParser.parserOnIncomingClient (_http_client.js:641:27) at HTTPParser.parserOnHeadersComplete (_http_common.js:126:17) at Socket.socketOnData (_http_client.js:509:22) at Socket.emit (events.js:315:20) at addChunk (internal/streams/readable.js:309:12) at readableAddChunk (internal/streams/readable.js:284:9) at Socket.Readable.push (internal/streams/readable.js:223:10)

Corresponding config enrty is:

            {
                "name": "Epson ET-2756",
                "address": "http://epson-et-2756:631/ipp/print",
                "polling": 30,
                "marker": true,
                "manufacturer": "Epson",
                "model": "Eco Tank ET-2756",
                "serialNumber": "123"
            }

If I use IP number instead of DNS name I got the same. With marker = false I gott also this error, but without details error message first time after restarting hombridge.

Maybe helpful additional information from Discovery app on my iPhone: mopria-certified = 1.3 rp = ipp/print TLS = 1.2 txtvers = 1 ty = EPSON ET-2750 Series

Thanks in advance.

Hi, any idea or newa for this issue?

  1. Start the web page of the Printer http://epson-et-2756 do not take care about the security hint . Epson uses private keys

  2. on the webpage login as administrator : Password is Allways the serialnumber of your printer.

  3. On top of page select "advanced Settings"

  4. on left side select : "services " Protocol"

There you should find " IPP settings" Activate them if not allready done and "ALLOW" them .

SAVE And then restart again

After a while the ERROR 426 will be disapeer .

It works now on My Epson ET 2550 and ET2821
