我有麻烦打印到标签打印机,代码在一个打印4“标签”,任何帮助(附加标签的图片)
Code Bellow打印给兄弟QL-500标签打印机.它打印到3.5“by 1.1”标签
如果有人可以帮助我更好地了解代码,这也是很棒的

解决方法
哇,我不能告诉你我喜欢用Java打印多少东西,当它的工作,这是伟大的…

如果您尝试并指定纸张尺寸和页边距,我知道PrintDialog有一些不一致的情况,而且老实说这是另一天的问题.
我发布的代码能够在Dymo LabelWriter 400 Turbo上相继打印两个标签,而不会出现问题
更新
还应该提到,我认为你基本上缺少PageFormat.setPaper
更新与Barbaque BarCode
从文件示例中打印…
Barcode b = BarcodeFactory.createCode128("Hello");
b.setResolution(72);
File f = new File("mybarcode.png");
// Let the barcode image handler do the hard work
BarcodeImageHandler.savePNG(b,f);
.
.
.
public static class PrintFromFile implements Printable {
@Override
public int print(Graphics graphics,int pageIndex) throws PrinterException {
int result = NO_SUCH_PAGE;
if (pageIndex == 0) {
graphics.translate((int)pageFormat.getimageableX(),(int)pageFormat.getimageableY());
result = PAGE_EXISTS;
try {
// You may want to rescale the image to better fit the label??
BufferedImage read = ImageIO.read(new File("mybarcode.png"));
graphics.drawImage(read,null);
} catch (IOException ex) {
ex.printstacktrace();
}
}
return result;
}
}
直接打印到图形上下文
Barcode b = BarcodeFactory.createCode128("Hello");
b.setResolution(72);
.
.
.
public static class PrintToGraphics implements Printable {
private Barcode b;
private PrintToGraphics(Barcode b) {
this.b = b;
}
@Override
public int print(Graphics graphics,int pageIndex) throws PrinterException {
int result = NO_SUCH_PAGE;
if (pageIndex == 0) {
result = PAGE_EXISTS;
int x = (int)pageFormat.getimageableX();
int y = (int)pageFormat.getimageableY();
int width = (int)pageFormat.getimageableWidth();
int height = (int)pageFormat.getimageableHeight();
graphics.translate(x,y);
try {
b.draw((Graphics2D)graphics,0);
} catch (OutputException ex) {
ex.printstacktrace();
}
}
return result;
}
}
最后但并非最不重要的是,直接从“examples”目录下载
public class PrintingExample
{
public static void main(String[] args)
{
try
{
Barcode b = BarcodeFactory.createCode128("Hello");
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintable(b);
if (job.printDialog())
{
job.print();
}
}
catch (Exception e)
{
e.printstacktrace();
}
}
}
