      org.freedesktop.portal.Print:
      @short_description: Portal for printing

The Print portal allows sandboxed applications to print.

Due to the way in which printing requires bi-directional communication
      using this portal will often require applications to make multiple requests:
      First use org.freedesktop.portal.Print.PreparePrint() to obtain print settings,
      use them to format your output, then use org.freedesktop.portal.Print.Print()
      to print the formatted document. It is expected that high-level toolkit
      APIS such as GtkPrintOperation will hide most of this complexity.

This documentation describes version 1 of this interface.

  <interface name="org.freedesktop.portal.Print">
    <!--
        Print:
        @parent_window: Identifier for the application window, see <link linkend="parent_window">Common Conventions</link>
        @title: Title for the print dialog
        @fd: File descriptor for reading the content to print
        @options: Vardict with optional further information
        @handle: Object path for the #org.freedesktop.portal.Request object representing this call

Asks to print a file.

The file must be passed in the form of a file descriptor open for reading.
        This ensures that sandboxed applications only print files that they have
        access to.

If a valid token is present in the @options, then this call will print
        with the settings from the Print call that the token refers to. If
        no token is present, then a print dialog will be presented to the user.

Note that it is up to the portal implementation to determine how long
        it considers tokens valid.

Supported keys in the @options vardict:
        <variablelist>
