Example 1 with PrinterURI

use of javax.print.attribute.standard.PrinterURI in project jdk8u_jdk by JetBrains.

the class UnixPrintServiceLookup method addPrintServiceToList.

private int addPrintServiceToList(ArrayList printerList, PrintService ps) {
    int index = printerList.indexOf(ps);
    // Check if PrintService with same name is already in the list.
    if (CUPSPrinter.isCupsRunning() && index != -1) {
        // Bug in Linux: Duplicate entry of a remote printer
        // and treats it as local printer but it is returning wrong
        // information when queried using IPP. Workaround is to remove it.
        // Even CUPS ignores these entries as shown in lpstat or using
        // their web configuration.
        PrinterURI uri = (PrinterURI) ps.getAttribute(PrinterURI.class);
        if (uri.getURI().getHost().equals("localhost")) {
            IPPPrintService.debug_println(debugPrefix + "duplicate PrintService, ignoring the new local printer: " + ps);
            // Do not add this.
            return index;
        }
        PrintService oldPS = (PrintService) (printerList.get(index));

            IPPPrintService.debug_println(debugPrefix + "duplicate PrintService, removing existing local printer: " + oldPS);
            printerList.remove(oldPS);
