Unsupported device HP Color LaserJet Pro M283fdw about node-hp-scan-to HOT 3 CLOSED

Hi,

The reason it fails is that your printer is not supported because there is no WalkupScanToCompManifestURI or WalkupScanManifestURI in the DiscoveryTree. That's why you can also read Unknown device! (see

These allow the application to register a computer as a target.

I don't know how the - Scan to Computer - feature works on this device. Without a complete record of the communication under Windows using the original hp software with the device, it's impossible to do the retro-engineering to make this device work in this project.

Ah I see, thanks for the explanation. I've been researching this myself since I made this post and I found some threads on HP's support forum from customer service reps which (vaguely) mention that "scan to computer" was removed from some MFP models due to bugs. I guess it was easier to just deprecate the function entirely and push people to use "scan to network path" instead. Annoying considering these printers are also stuck on SMB v1!

Is there a way I could record the communication between the printer and Windows? I'd be happy to provide more info if it would help diagnose the problem and extend functionality to any other printers similarly afflicted.

I used wireshark to capture the network traffic while interacting with the application and the device and I've been able to understand what were happening : https://github.com/manuc66/node-hp-scan-to/blob/043466417ed3e198c5e0d338e718d17c005a3054/protocol_doc/HP%20Officejet%206500%20E710n-z.md

Hopefully the trafic was in clear text not http with that printer so it was a bit easier. If you are facing https traffic you may try to use this kind of technique : https://briannalaird.com/tutorials/decrypt-https-traffic-in-wireshark-on-a-windows-machine
