如何使用标准的Windows打印对话框而不是Java对话框进行打印。我在用标签打印机打印条形码时遇到了问题。当我通过Java-Print对话框打印时,我得到一个错误,告诉我要打印的文档的格式是错误的。当我打印到XPS文件,然后通过Windows打印它时,一切工作正常。希望有谁能帮我。
问候

try {
Code128Bean bean = new Code128Bean();
final int dpi = 150;
//Configure the barcode generator
bean.setModuleWidth(UnitConv.in2mm(2.0f / dpi)); //makes the narrow bar width exactly one pixel
bean.setBarHeight(10);
bean.doQuietZone(false);
//Open output file
File outputFile = new File("out.png");
OutputStream out;
out = new FileOutputStream(outputFile);
//Set up the canvas provider for monochrome PNG output
BitmapCanvasProvider canvas = new BitmapCanvasProvider(out, "image/x-png", dpi, BufferedImage.TYPE_BYTE_BINARY, false, 90);
// 200x 10
//Generate the barcode
bean.generateBarcode(canvas, barcode);
//Signal end of generation
canvas.finish();
out.close();
paintComponent(labelArtikelbezeichnung.getText());
String working_dir = System.getProperty("user.dir");
try {
Runtime rt = Runtime.getRuntime();
String command = "C:\\WINDOWS\\system32\\rundll32.exe C:\\WINDOWS\\system32\\shimgvw.dll,ImageView_Fullscreen " + "" + working_dir + "\\out.png";
System.out.println(command);
Process pr = rt.exec(command);
BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream()));
String line=null;
while((line=input.readLine()) != null) {
System.out.println(line);
}
int exitVal = pr.waitFor();
System.out.println("Exited with error code "+exitVal);
} catch(Exception e) {
System.out.println(e.toString());
e.printStackTrace();
}
} catch (IOException ex) {
System.out.println("Error creating the Barcode");
}程序将打开Windows打印和传真对话框,我可以从中进行打印。程序调整了图像的大小,一切都工作得很完美。

这可能是由标签打印机本身导致的错误,而不是Java。尝试使用Java将数据写入XPS文件,然后从Java打印该文件。
