POunable to print UTF8 document using Java Print Service API on windows

Body
copied!<p>I have been trying to print a text document containing Russian letters using the Java Print Service API on windows OS, but no luck so far. The printer prints the file, but the unicode characters get garbled. </p> <p>While running the program, the VM argument <strong>-Dfile.encoding=utf8</strong> was specified</p> <h2>Following is the code</h2> <pre><code> import java.io.DataInputStream; import java.io.FileInputStream; import java.io.UnsupportedEncodingException; import javax.print.Doc; import javax.print.DocFlavor; import javax.print.DocPrintJob; import javax.print.PrintException; import javax.print.PrintService; import javax.print.PrintServiceLookup; import javax.print.SimpleDoc; import javax.print.attribute.HashPrintRequestAttributeSet; import javax.print.attribute.PrintRequestAttributeSet; import javax.print.attribute.standard.Sides; public class PrintUtf8Doc { public static void main(String[] args) throws UnsupportedEncodingException { FileInputStream textstream=null; DataInputStream da=null; byte buff[]=new byte[1024*20]; try { textstream = new FileInputStream("D:\\test\\russian.txt"); da=new DataInputStream(textstream); da.read(buff); } catch (Exception e) { e.printStackTrace(); } if (textstream == null) { return; } // Set the document type DocFlavor myFormat = DocFlavor.BYTE_ARRAY.AUTOSENSE; // Create a Doc Doc myDoc = new SimpleDoc(buff, myFormat, null); // Build a set of attributes PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet(); aset.add(Sides.DUPLEX); System.out.println("Host Encoding: "+myFormat.hostEncoding); PrintService service = PrintServiceLookup.lookupDefaultPrintService(); DocFlavor flavs[]=service.getSupportedDocFlavors(); for(DocFlavor flavor: flavs){ System.out.println(flavor.toString()); } // Create a print job from one of the print services if (service!=null) { DocPrintJob printJob=service.createPrintJob(); try { printJob.print(myDoc, aset); } catch (PrintException e) { e.printStackTrace(); } } } } ------------------------------------------------------------------- The supported flavors are printed in the console Host Encoding: UTF8 image/gif; class="[B" image/gif; class="java.io.InputStream" image/gif; class="java.net.URL" image/jpeg; class="[B" image/jpeg; class="java.io.InputStream" image/jpeg; class="java.net.URL" image/png; class="[B" image/png; class="java.io.InputStream" image/png; class="java.net.URL" application/x-java-jvm-local-objectref; class="java.awt.print.Pageable" application/x-java-jvm-local-objectref; class="java.awt.print.Printable" application/octet-stream; class="[B" application/octet-stream; class="java.net.URL" application/octet-stream; class="java.io.InputStream" </code></pre> <hr> <p>I tried even changing the docFlavor to "application/octet-stream; class="java.io.InputStream" and passed the inputStream to the SimpleDoc() constructor, but still it was the same issue</p> <p>Looks like even if the platform encoding was set to UTF8, the Java Print Service on windows is not able to ode the bytes correctly.</p> <p>Is there any setting that needs to be done or corrected? Any suggestions would be of great help</p>
