java - 在 Java 中强制目标打印机

Question

有没有办法使用 HashPrintRequestAttributeSet 在 java 中强制使用目标打印机？

我不希望用户能够在打印对话框中更改打印机

谢谢

必须通过艰难的方式来解决这个问题，但为了子孙后代，这是我的一些代码:

PrintService[] printServices;
PrintService printService;
PageFormat pageFormat;

String printerName = "Your printer name in Devices and Printers";

PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet();
printServiceAttributeSet.add(new PrinterName(printerName, null));
printServices = PrintServiceLookup.lookupPrintServices(null, printServiceAttributeSet);

pageFormat = new PageFormat(); // If you want to adjust heigh and width etc. of your paper.
pageFormat = printerjob.defaultPage();

PrinterJob printerjob = PrinterJob.getPrinterJob();

printerjob.setPrintable(new Server(), pageFormat); // Server was my class's name, you use yours.

try {
    printService = printServices[0];
    printerjob.setPrintService(printService); // Try setting the printer you want
} catch (ArrayIndexOutOfBoundsException e) {
    System.err.println("Error: No printer named '" + printerName + "', using default printer.");
    pageFormat = printerjob.defaultPage(); // Set the default printer instead.
} catch (PrinterException exception) {
    System.err.println("Printing error: " + exception);
}

try {
    printerjob.print(); // Actual print command
} catch (PrinterException exception) {
    System.err.println("Printing error: " + exception);
}
