Ubuntu中的Java打印

Ubuntu中的Java打印,java,ubuntu,printing,Java,Ubuntu,Printing,我正在开发一个在Ubuntu中打印数据的小应用程序,问题是我的应用程序在windows中运行良好,使用: PrintService service = PrintServiceLookup.lookupDefaultPrintService(); FileInputStream fis = new FileInputStream(myfile); DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE; DocPrintJob job = se

我正在开发一个在Ubuntu中打印数据的小应用程序,问题是我的应用程序在windows中运行良好,使用:

PrintService service = PrintServiceLookup.lookupDefaultPrintService();

FileInputStream fis = new FileInputStream(myfile);

DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
DocPrintJob job = service.createPrintJob();

Doc doc = new SimpleDoc(fis, flavor, null);
job.print(doc, null);
fis.close();

然而在Ubuntu中,它只是不打印。对于我正在使用的打印API,Linux打印是否有任何特殊配置?还是我遗漏了什么?

我认为,您的打印机在操作系统中不是默认安装的。检查您的“服务”是什么。 您也可以从“打印”对话框中选择打印机,如下所示:

PrintRequestAttributeSet pras =
                new HashPrintRequestAttributeSet();
        DocFlavor flavor = DocFlavor.INPUT_STREAM.TEXT_PLAIN_UTF_8;
        PrintRequestAttributeSet aset =
                new HashPrintRequestAttributeSet();
        aset.add(MediaSizeName.ISO_A4);
        aset.add(new Copies(1));
        aset.add(Sides.ONE_SIDED);
        aset.add(Finishings.STAPLE);

        PrintService printService[] =
                PrintServiceLookup.lookupPrintServices(flavor, pras);
        PrintService defaultService =
                PrintServiceLookup.lookupDefaultPrintService();
        PrintService service = ServiceUI.printDialog(null, 200, 200,
                printService, defaultService, flavor, pras);
        if (service != null) {
            try {
                FileInputStream fis = new FileInputStream("c://test.txt");
                DocAttributeSet das = new HashDocAttributeSet();
                Doc doc1 = new SimpleDoc(fis, flavor, das);

                DocPrintJob job1 = service.createPrintJob();

                try {
                    job1.print(doc1, pras);
                } catch (PrintException e) {
                    e.printStackTrace();
                }
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }
        }
if (Desktop.isDesktopSupported()){
    Desktop desktop = Desktop.getDesktop();
    if (desktop.isSupported(Desktop.Action.PRINT))
    {
        try {
            File html1 = new File("c://file1.html");
            desktop.print(html1);
            desktop.print(html2);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
有些打印机不支持文本,只支持图像。您还可以使用操作系统本机方法简单地打印html文件,如下所示:

PrintRequestAttributeSet pras =
                new HashPrintRequestAttributeSet();
        DocFlavor flavor = DocFlavor.INPUT_STREAM.TEXT_PLAIN_UTF_8;
        PrintRequestAttributeSet aset =
                new HashPrintRequestAttributeSet();
        aset.add(MediaSizeName.ISO_A4);
        aset.add(new Copies(1));
        aset.add(Sides.ONE_SIDED);
        aset.add(Finishings.STAPLE);

        PrintService printService[] =
                PrintServiceLookup.lookupPrintServices(flavor, pras);
        PrintService defaultService =
                PrintServiceLookup.lookupDefaultPrintService();
        PrintService service = ServiceUI.printDialog(null, 200, 200,
                printService, defaultService, flavor, pras);
        if (service != null) {
            try {
                FileInputStream fis = new FileInputStream("c://test.txt");
                DocAttributeSet das = new HashDocAttributeSet();
                Doc doc1 = new SimpleDoc(fis, flavor, das);

                DocPrintJob job1 = service.createPrintJob();

                try {
                    job1.print(doc1, pras);
                } catch (PrintException e) {
                    e.printStackTrace();
                }
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }
        }
if (Desktop.isDesktopSupported()){
    Desktop desktop = Desktop.getDesktop();
    if (desktop.isSupported(Desktop.Action.PRINT))
    {
        try {
            File html1 = new File("c://file1.html");
            desktop.print(html1);
            desktop.print(html2);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

如果我将“myfile”替换为指向文本文件的路径,则您的代码在这里工作。您的系统中是否正确安装了打印机?你能在其他应用程序中打印吗?e、 g.gedit,gvim…?我可以使用cat“filename”| lpr从终端打印…通常“myfile”是来自打开的文件对话框的路径字符串…我删除了“eclipse”标记。这个标签是专门用来回答关于Eclipse(IDE)的问题的,我在Linux(Ubuntu12.10)上也遇到过同样的问题。我唯一能打印的文件是PDF和PS文件。纯文本、HTML、图像生成了一个空白页。也尝试了该对话框,它根本不起作用,我在那里看到打印机,当我单击“打印”时,没有作业发送到我的打印队列…:(对不起,我忘了将DocFlavor更改为“TEXT\u PLAIN\u UTF\u 8”。请尝试此操作,或者尝试将数据打印为html。我将此添加到答案中。
