Printing a "Printable" object to a PDF file silently

How can I print a "java.awt.print.Printable" object silently to a PDF?
Few things to note:
I do not have the data as a pdf file
I'm working on existing code, so I cannot step away from the printable interface
So i can print it just fine with job.printDialog(). But I need to be able to do that silently (without user input). The available PDF printer is "Adobe PDF", I suppose others can be installed if needed.
Here's the basic code:
Printable printout = /*object*/;
Book pageable = new Book();
pageable.append(printout, pageFormat);
DocFlavor flavor = DocFlavor.SERVICE_FORMATTED.PAGEABLE;
PrintRequestAttributeSet patts = new HashPrintRequestAttributeSet();
// Add Filepath?
PrintService[] ps = PrintServiceLookup.lookupPrintServices(flavor, patts);
if (ps.length == 0)
throw new IllegalStateException("No Printer found");
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintService(ps[0]);
job.setPrintable(printout);

I eventually decided to step away from trying to do it in java and instead used a PDF printer which has the option to print silently to a predetermined path.
DocFlavor flavor = DocFlavor.SERVICE_FORMATTED.PAGEABLE;
PrintRequestAttributeSet patts = new HashPrintRequestAttributeSet();
PrintService[] ps = PrintServiceLookup.lookupPrintServices(flavor, patts);
System.out.println("Available printers: " + Arrays.asList(ps));
PrintService myService = null;
for (PrintService printService : ps) {
if (printService.getName().contains("PDF Writer - bioPDF")) {
myService = printService;
break;
}
}
if (myService == null) {
throw new IllegalStateException("bioPDF Printer not found");
}
PrinterJob job = PrinterJob.getPrinterJob();
job.setJobName(jobName);
job.setPrintService(myService);
job.setPrintable(printout);
job.print();

Java send txt file to Printer

I have made a program that generates text files (.txt) and then displays them in a textArea. I want to take this one step farther and be able to print the text file. It feels like I have tried everything but always get the same result. The text file always varies in length and is normally more than one page long. Using the code below my text file prints but instead of printing multiple pages it prints each page on one/sixth of the a single sheet in landscape. I just need it to print normally. Vertically on multiple pages. I am running on a Linux environment and it is an Epson printer. Any suggestions or feedback would be greatly appreciated.
public static void tryDoc(){
try{
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
pras.add(OrientationRequested.PORTRAIT);
DocFlavor flavor = DocFlavor.INPUT_STREAM.TEXT_PLAIN_UTF_8;
PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor, pras);
PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
PrintService service = ServiceUI.printDialog(null, 200, 200, printService, defaultService, flavor, pras);
if(service != null){
DocPrintJob job = service.createPrintJob();
FileInputStream input = new FileInputStream(FileName);
DocAttributeSet das = new HashDocAttributeSet();
Doc doc = new SimpleDoc(input,flavor,das);
job.print(doc, pras);
}
}
catch(Exception e){
System.out.println("Failed");
}
}

javax print not actually printing anything

Desperately trying to print a document using the following code. A document is being added to the printer queue but nothing actually comes out of the printer.
PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
PrintService printService[] = PrintServiceLookup.lookupPrintServices(null, null);
InputStream stream = new ByteArrayInputStream("hello world!\f".getBytes("UTF8"));
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
pras.add(new Copies(1));
DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
PrintService service = ServiceUI.printDialog(null, 200, 200, printService, defaultService, flavor, pras);
DocPrintJob job = service.createPrintJob();
DocAttributeSet das = new HashDocAttributeSet();
Doc doc = new SimpleDoc(stream, flavor, das);
PrintJobWatcher pjw = new PrintJobWatcher(job);
job.print(doc, pras);
pjw.waitForDone();
The print dialog I get shows the correct default printer (as below), plus the list of other available printers:
If I change the printer to "Microsoft print to PDF", I get an empty (0kb) pdf. Interestingly, if I tick "Print to File" I get a prn file with the correct contents ("hello world!FF").
What am I missing?

Correct way to send escape codes (raw data) to printer

In the context of a bigger application, my applet needs to print some data to a Zebra or a Dymo (depending on what the user has installed) label printer.
The data i receive is in an escaped form, data that i just need to send to the printer and let it interpret it.
Searching i've found two solutions.
Method 1:
byte[] printdata;
PrintService pservice = PrintServiceLookup.lookupDefaultPrintService(); //or get the printer in some other way
DocPrintJob job = pservice.createPrintJob();
DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
Doc doc = new SimpleDoc(printdata, flavor, null);
and method 2:
PrintStream printStream = new PrintStream(new FileOutputStream(“LPT1”));
printStream.print(“Hello World”);
printStream.close();
I need this to work cross-platform, with printers using the USB or the serial port.
What is the correct way to implement this behaviour?
One problem with method 2 is that i would need to find the URL of the printer in same way...

public String rawprint(String printerName, String conte) {
String res = "";
PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet();
printServiceAttributeSet.add(new PrinterName(printerName, null));
PrintService printServices[] = PrintServiceLookup.lookupPrintServices(null, printServiceAttributeSet);
if (printServices.length != 1) {
return "Can't select printer :" + printerName;
}
byte[] printdata = conte.getBytes();
PrintService pservice = printServices[0];
DocPrintJob job = pservice.createPrintJob();
DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
Doc doc = new SimpleDoc(printdata, flavor, null);
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
try {
job.print(doc, aset);
} catch(Exception e){
res = e.getMessage();
}
return res;
}
Works cool in javafx

Hex printouts are trustworthy. Call String.getBytes(encoding), then use System.out.format to print each byte as a hexadecimal number.

Printing a pdf file using javax.print

Hey everyone ,
I'm facing a real problem here while trying to print a pdf file using java print .
The problem is that when i send the file to the printer using print() method with cute pdf the file is well printed but with a real printer it couldn't be done .
`
try{
File file = new File(toprint);
InputStream is = new BufferedInputStream(new FileInputStream(file));
DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
DocPrintJob job = p.createPrintJob();//p here is my printservice printer
HashPrintRequestAttributeSet printRequestSet = new HashPrintRequestAttributeSet();
HashDocAttributeSet ds=new HashDocAttributeSet();
Doc doc = new SimpleDoc(is, flavor, null);
job.print(doc, aset);
}
catch(Exception e){
System.out.println("An exception occured while printing the file "+ e);
}
`
I've tried it so many times but it doesn't work.
Any ideas?

I think your printer may not have support for pdf, in this case you will have to render it using a pdf renderer.
Look at http://java.net/projects/pdf-renderer and pageable print page.
If you find it helpful I will provide code samples.
