Question

我对Java的打印机Api没什么经验。现在我正在研究一个托管在linux服务器上的java entrprise应用程序，这个应用程序打印一些文档，实际上我正在使用

javax.print中

打包管理这种情况。这是我用来打印的代码：

FileInputStream in = new FileInputStream(fileToPrint);
DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
PrintRequestAttributeSet  pras = new HashPrintRequestAttributeSet();
pras.add(new Copies(1));
Doc doc = new SimpleDoc(in, flavor, null);
DocPrintJob job = myService.getPrintService().createPrintJob();
PrintJobWatcher pjw = new PrintJobWatcher(job,daProcessare);
job.print(doc, pras);
pjw.waitForDone();
in.close();


public PrintJobWatcher(DocPrintJob job,FatturaCodaInvio fileToProcess) {

    job.addPrintJobListener(new PrintJobAdapter() {

        public void printJobCanceled(PrintJobEvent pje) {
            System.out.println("Print Canceled");
            allDone(false,"Print Canceled");
        }
        public void printJobCompleted(PrintJobEvent pje) {
            System.out.println("Print Completed");
            allDone(true,"Print Completed");
        }
        public void printJobFailed(PrintJobEvent pje) {
            System.out.println("Print failed");
            allDone(false,"Print failed");
        }
        public void printJobNoMoreEvents(PrintJobEvent pje) {
            System.out.println("Print No More Events");
            allDone(true,"Print No More Events");
        }
        void allDone(boolean esito, String info) {
            synchronized (PrintJobWatcher.this) {
                System.out.println("Printing done ...");
                PrintJobWatcher.this.notify();
            }
        }
    });     
}

现在在某些情况下，我几乎无法控制打印机。例如，我无法承担如果我的打印机没有准备好或者有问题，那么我想在发送文件之前检查mi打印机的状态。要做到这一点，我谷歌搜索，我发现一些图书馆谎言cups4j可能可以帮助我。是否有人遇到过同样的问题？你能给我一些关于这个的建议吗？

使用javax.print在java中打印
