Hp LaserJet M2727dnf - Githubissues

Hi, hope this is the right place for this prob.

My MFP needs the proprietary HP-binary-plugin (e.g. hplip-3.22.4-plugin.run) to work correctly. I am using a network setup. (Printer: 192.168.1.233 on localnet and 10.0.0.29 on different network, Airsane: 192.168.1.234, IPP_Service_Host: 192.168.1.10) the printers http service pages shows an WS-Discovery Service so we should have a WSD up and running. But it seems to not register in MDNS/WSSD/ZEROCONF and so airscan is not able to detect it. I tested my normal setup with an avahi-reflector and also moved the printer to the same network segment as airscan. It made no difference.

while tcpdumping a hpaio:// scan (scanimage --test --verbose --progress) i was able to see the WSD XML the printer reported:

And i was able to forge a curl post for wsdiscovery - So airscan stuff should work

curl --verbose --header Accept: --header "Content-Type: application/soap+xml; charset=utf-8"  --header "Transfer-Encoding: chunked" --user-agent "gSOAP/2.7" --data @req  10.0.0.29:8289/StableWSDiscoveryEndpoint/schemas-xmlsoap-org_ws_2005_04_discovery

avahi (thx to reflector) lists the printer on localnet and different net

airscan-discover -d

e.g.
MDNS: resolve-ipv4("_ipp._tcp", "HP_LaserJet_M2727nf_MFP_fax @ odroidn2"): 192.168.1.10:631
WSDD: directed probe: trying if=enp0s3, addr=192.168.1.10
WSDD: HTTP POST http://192.168.1.10/StableWSDiscoveryEndpoint/schemas-xmlsoap-org_ws_2005_04_discovery
WSDD: HTTP resolving 192.168.1.10 80
WSDD: HTTP trying 192.168.1.10:80

But airscan only seems to scan Printers reporting _ipp._tcp and _ipps._tcp, which is not ideal in my case. The printer does not provide ipp and so the ipp service address is provided via DrPsychick docker-cups-airprint logfile airscan-discover -d (valid 3weeks) pcap success scanning hpaio (valid 2weeks)
