Question

我尝试使用以下代码打印JPanel：

try {
    PrinterJob gap = PrinterJob.getPrinterJob();
    gap.setPrintable(this);
    boolean top = gap.printDialog();

    if(top){
        gap.print();

    }

} catch (PrinterException ex) {
    JOptionPane.showMessageDialog(null, " ERROR DEL PROGRAMA", "ERROR \n " + ex , JOptionPane.INFORMATION_MESSAGE);
}

但是，它会出现选择打印机的配置菜单。我不想选择打印机，我希望它是默认打印机或者在代码中选择打印机。

如果您不想显示打印对话框，请删除＆＃39; gap.printDialog（）＆＃39;，您只需要使用＆＃39; gap.print（）＆＃39;

你可以做一些像这样的事情：

PrinterJob gap = PrinterJob.getPrinterJob();
PageFormat pf = gap.defaultPage();

//Manually assign some of the basic print settings (More advanced things may require you to write your own code)
gap.setJobName("My Print Jnb");

//Set custom page size?
Paper paper = new Paper();
paper.setSize(595, 842);
pf.setPaper(paper);

//Set page orientation?
pf.setOrientation(PageFormat.LANDSCAPE);

//Create the print job with our manual settings
gap.setPrintable(this, pf);

try
{
    //And finally print it out
    gap.print();
}
catch (PrinterException e)
{
    JOptionPane.showMessageDialog(null, " ERROR DEL PROGRAMA", "ERROR \n " + ex , JOptionPane.INFORMATION_MESSAGE);
}
