Hi folks,
 
I'm writing a JPOS application that is listening to Signature Capture bar code scanner results and my DS9808 is only sending back a valid JPEG about one in every three scans. Am I possibly doing something wrong.
 
I've scanned the barcode for USB (IBM Hand-held), Enable Signature Capture and JPEG Signature Format (although it's the default) and I'll include some code below.
 
public class Listen implements DirectIOListener, DataListener, ErrorListener, StatusUpdateListener{
public void dataOccurred(DataEvent de) {
 
...
            if(type == 501){
                try{
                    System.out.println("Bytes size start " + bytes.length);
                    byte typeByte = bytes[0];
                    System.out.println("typeByte " +typeByte);
                    byte sigType = bytes[1];
                    System.out.println("sigType " +sigType);
                    byte[] size = new byte[]{bytes[2], bytes[3], bytes[4], bytes[5]};
                    byte[] image = Arrays.copyOfRange(bytes, 6, bytes.length);
                    String base64 = Base64.encode(bytes);
                    System.out.println("Bytes size end " + image.length);
 
                    String s = new String(image);
                    FileOutputStream outputFile = new FileOutputStream("C:\\Users\\jwilliams\\Desktop\\output" + System.currentTimeMillis() + ".jpg");
                    OutputStreamWriter outputSW = new OutputStreamWriter(outputFile, "ISO-8859-1");
                    outputSW.write(s);
                    outputSW.close();
                    outputFile.close();
                    System.out.println("File Closed");
                    sendBeepCode(scn, "20");

Thanks for any help in advance!
