Hello,
I just face a strange problem. I think its not Spring-related, but I hope that someone could help anyway.
I have a PdfPrinter-class used by my SaleService which generates Order-Pdfs via iText and then delegates to PdfPrinter which prints files via Ghostscript which works very well in testcase and when printing a file while server-startup...
When I start my server >>AND PRINT A FILE ON SERVER-STARTUP<< I can invoke the print-method from clients and all files are well printed. I may close and restart one or more clients and can print again without problems...
When I invoke print() from client while NOT printing a file at server-startup, server and client do hang and nothing is printed...
The biggest problem. There is no Exception... Nothing... Simply not printing... :-(
The unknown problem occurs in the line where the printerjob is printed:
job.print(doc, aset);
when I out-comment this line, the server will obviously not print but it will not hang... So there must be the problem... But as I said, no Exception is thrown...
here is my implementation of PdfPrinter:
public class PdfPrinter {
public PdfPrinter() {}
public static void printPdf(String filename) {
System.out.println("filename: "+filename);
Doc doc = new PdfDoc(filename);
// Gets the format of the document
DocFlavor flavor = doc.getDocFlavor();
// Creates a new attribute set
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
PrintService defaultService =
PrintServiceLookup.lookupDefaultPrintService();
System.out.println("defaultService: "+defaultService);
//PrintService[] services = PrintServiceLookup.lookupPrintServices(dFlavor, aset);
DocPrintJob job = defaultService.createPrintJob();
System.out.println("PrintJob created: "+job);
try {
System.out.println("printing");
job.print(doc, aset);
} catch (Exception e) {
e.printStackTrace();
}
}
}
Perhaps there is some serverside printer-init stuff that I missed to enable client-invoked-printing and someone yet had the same problem and could gave me a hint.
Again. Everything is fine when I print a file on server-startup, but i want to prevent my server from printing a file on every startup to enable printing for clients... ;)
Thanks for help...
