        Bug Description:

        Spooling print jobs takes far too long. Using the javax.print libraries, a
        print job where can spool 1053 pages in less than 15 seconds. Using the new
        javafx libraries, this takes about 20 minutes. This calculates being to over
        60 times slower than the javax.print APIs.

        Realize that printing, in general, is limited to the physical printing of the
        pages, but the user experience here is a factor as well. Previously, a user
        could start a print, wait 15 seconds, exit the application, and then just
        wait for the printer to finish.

        An instance where this may be even more of a factor is printing to a virtual
        printer, like a "Print to PDF" printer. Doing this on my desktop, printing
        to a PDF file does not add any appreciable amount of time, so I have my 1053
        page PDF ready to go in roughly 15 seconds. With the javafx API, this would
        take 20 minutes of actual user time.

        One option would be to make the wait time smaller. There are some 1 second
        waits in the print code, which is far too long in my situation.

        A better possibility would be to make the notify() more aggressive. In
        waitForNextPage(), "pageDone" is set to true, but never notifies threads
        waiting on it to wake up. This seems like an oversight. Since a thread is
        waiting on this flag, like implPrintPage(), it seems like code changing the
        value of this flag should notify it so it can re-check the value.

        The proposed change seems as safe as the existing code, since nothing in the
        existing code prevents the printing thread from sporadically waking up at
        this point anyway. This change would just encourage that to happen every
        private boolean waitForNextPage(int pageIndex) {
        pageDone = true;
        currPageInfo = newPageInfo;
        newPageInfo = null;
        currPageIndex = pageIndex;
        currPageFormat = getPageFormatFromLayout(currPageInfo.getPageLayout());
        //Suggested Addition Start
        synchronized (monitor) {
        //Suggested Addition End
        return true;

               private void implPrintPage(PageLayout pageLayout, Node node) {
                       while (!pageDone) {
                            synchronized (monitor) {
                                try {
                                } catch (InterruptedException e) {
