      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>
