I want to connect HP LaserJet Professional m1132 MFP printer, but fail. And I find model shows "HP LaserJet Professional m1132 MFP, hpcups 3.14.3, requires proprietary plugin".
what is the meaning of "requires proprietary plugin", it means I need install manually the hp plugin at this docker? or I need install hp plugin on my mac that connect to CUPS server? or others? Thanks.

i followed the instructions for container setup using command:
docker run -d --name=printsvr
--net="host"
--privileged=true
-e "CUPS_USER_ADMIN"="admin"
-e "CUPS_USER_PASSWORD"="pass"
-e TZ="Asia/Shanghai"
-e HOST_OS="Synology"
-e "TCP_PORT_631"="631"
-v "/volume1/docker/airprint/config":"/config"
-v /dev:/dev
-v "/volume1/docker/airprint/avahi":"/etc/avahi/services"
-v /var/run/dbus:/var/run/dbus "mnbf9rca/cups-google-print"

but when i tried to login to the webui, there is always login loop whatever credentials i input (of course i tried the one in my command).
any hint?
