    /* Collation and copy flags.
     * The Windows PRINTDLG struct has a nCopies field which on return
     * indicates how many copies of a print job an application must render.
     * There is also a PD_COLLATE member of the flags field which if
     * set on return indicates the application generated copies should be
     * collated.
     * Windows printer drivers typically - but not always - support
     * generating multiple copies themselves, but uncollated is more
     * universal than collated copies.
     * When they do, they read the initial values from the PRINTDLG structure
     * and set them into the driver's DEVMODE structure and intialise
     * the printer DC based on that, so that when printed those settings
     * will be used.
     * For drivers supporting both these capabilities via DEVMODE, then on
     * return from the Print Dialog, nCopies is set to 1 and the PD_COLLATE is
     * cleared, so that the application will only render 1 copy and the
     * driver takes care of the rest.
     *
     * Applications which want to know what's going on have to be DEVMODE
     * savvy and peek at that.
     * DM_COPIES flag indicates support for multiple driver copies
     * and dmCopies is the number of copies the driver will print
     * DM_COLLATE flag indicates support for collated driver copies and
     * dmCollate == DMCOLLATE_TRUE indicates the option is in effect.
     *
     * Multiple copies from Java applications:
     * We provide API to get & set the number of copies as well as allowing the
     * user to choose it, so we need to be savvy about DEVMODE, so that
     * we can accurately report back the number of copies selected by
     * the user, as well as make use of the driver to render multiple copies.
     *
     * Collation and Java applications:
     * We presently provide no API for specifying collation, but its
     * present on the Windows Print Dialog, and when a user checks it
     * they expect it to be obeyed.
     * The best thing to do is to detect exactly the cases where the
     * driver doesn't support this and render multiple copies ourselves.
     * To support all this we need several flags which signal the
     * printer's capabilities and the user's requests.
     * Its questionable if we (yet) need to make a distinction between
     * the user requesting collation and the driver supporting it.
     * Since for now we only need to know whether we need to render the
     * copies. However it allows the logic to be clearer.
     * These fields are changed by native code which detects the driver's
     * capabilities and the user's choices.

Display a dialog to the user allowing the modification of a PageFormat instance. The page argument is used to initialize controls in the page setup dialog. If the user cancels the dialog, then the method returns the original page object unmodified. If the user okays the dialog then the method returns a new PageFormat object with the indicated changes. In either case the original page object will not be modified. 
Params:
page –    the default PageFormat presented to the user
                   for modification
Throws:
HeadlessException – if GraphicsEnvironment.isHeadless()
returns true.
