By unchecking Interactive mode you can set this specific printer to only send jobs to the
server, without further user interaction. In that case, the printer will not pop up a browser
window. Nevertheless, messages will pop up in the tray area, informing about transfer, success
or failure.
When the Interactive mode is disabled, the HTTP action for interaction field also becomes
disabled.
Accept all certificates: By default, if HTTPS is set as protocol (see above), the Printer Driver
will only accept valid certificates on the server side for the transfer. However in some cases a
self-signed certificate may be seen as sufficient for the transfer. In that case, the root validation
of the certificate can be switched off by checking this option.
HTTP action for interaction
Enter the HTTP action as defined in the related Workflow HTTP Input plugin, including any
path components.
The final URL for interaction is composed of the HTTP action for interaction and the protocol,
host and port of the URL for print job submission, because both HTTP actions must run in the
same Workflow.
