Force target printer in Java
提问by jtnire
Is there a way to force the target printer in java, using HashPrintRequestAttributeSet ?
有没有办法在 java 中使用 HashPrintRequestAttributeSet 强制目标打印机？
I don't want the user to be able to change the printer in the printdialog
我不希望用户能够在打印对话框中更改打印机
Thanks
谢谢

Had to figure this out the hard way, but for the future generations, here's some of my code:
不得不以艰难的方式解决这个问题，但对于后代，这是我的一些代码：
PrintService[] printServices;
PrintService printService;
PageFormat pageFormat;
String printerName = "Your printer name in Devices and Printers";
PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet();
printServiceAttributeSet.add(new PrinterName(printerName, null));
printServices = PrintServiceLookup.lookupPrintServices(null, printServiceAttributeSet);
pageFormat = new PageFormat(); // If you want to adjust heigh and width etc. of your paper.
pageFormat = printerjob.defaultPage();
PrinterJob printerjob = PrinterJob.getPrinterJob();
printerjob.setPrintable(new Server(), pageFormat); // Server was my class's name, you use yours.
try {
printService = printServices[0];
printerjob.setPrintService(printService); // Try setting the printer you want
} catch (ArrayIndexOutOfBoundsException e) {
System.err.println("Error: No printer named '" + printerName + "', using default printer.");
pageFormat = printerjob.defaultPage(); // Set the default printer instead.
} catch (PrinterException exception) {
System.err.println("Printing error: " + exception);
}
try {
printerjob.print(); // Actual print command
} catch (PrinterException exception) {
System.err.println("Printing error: " + exception);
}

My code to solve this :
我的代码来解决这个问题：
String printerNameDesired = "My Printer";
PrintService[] service = PrinterJob.lookupPrintServices(); // list of printers
DocPrintJob docPrintJob = null;
int count = service.length;
for (int i = 0; i < count; i++) {
if (service[i].getName().equalsIgnoreCase(printerNameDesired)) {
docPrintJob = service[i].createPrintJob();
i = count;
}
}
PrinterJob pjob = PrinterJob.getPrinterJob();
pjob.setPrintService(docPrintJob.getPrintService());
pjob.setJobName("job");
pjob.print();

I just solved this problem by running cmd command in Java
我刚刚通过在 Java 中运行 cmd 命令解决了这个问题
static void changeWindowsDefaultPrinter(String printerName) {
String cmdLine = String.format("RUNDLL32 PRINTUI.DLL,PrintUIEntry /y /n \"%s\"", printerName);
ProcessBuilder builder = new ProcessBuilder("cmd.exe", "/c", cmdLine );
builder.redirectErrorStream(true);
Process p = null;
try { p = builder.start(); }
catch (IOException e) { e.printStackTrace(); }
BufferedReader r = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = new String();
while (true) {
try {
line = r.readLine();
} catch (IOException e) {
e.printStackTrace();
}
if (line == null) { break; }
System.out.println( "result " + line);
}
}
And It's Wroked for Me :D
这对我来说很糟糕：D
