Question

I am developing an integrated Android application with a web service TomCat and laboratory (Eclipse Java EE) she arrived at a satisfactory level, performing queries, impressions on the default printer, all quiet, but as I get the service for Tomcat he does not perform printing it is as if there is no printer connected to the server.

The code below is used to perform printing when I am providing the service directly from Eclipse.

try{
InputStream prin = new ByteArrayInputStream(textoimp.getBytes());

INPUT_STREAM docFlavor = DocFlavor.INPUT_STREAM.AUTOSENSE;

SimpleDoc documentoTexto = new SimpleDoc(prin, docFlavor, null);

PrintService impressora = PrintServiceLookup.lookupDefaultPrintService(); // pega a impressora padrao 

PrintRequestAttributeSet printerAttributes = new HashPrintRequestAttributeSet();

printerAttributes.add(new JobName("Impressao", null));

printerAttributes.add(OrientationRequested.PORTRAIT);

printerAttributes.add(MediaSizeName.ISO_A4); // informa o tipo de folha

DocPrintJob printJob = ((PrintService) impressora).createPrintJob(); //the error occurs here , the printer is null

try{

printJob.print(documentoTexto, (PrintRequestAttributeSet)printerAttributes);//try to print

}

catch(PrintException e){ 

e.printStackTrace();
JOptionPane.showMessageDialog(null, "Não foi possível realizar a impressão !!", "Erro", JOptionPane.ERROR_MESSAGE); 

} 

prin.close(); 

} 

catch(Exception e){

e.printStackTrace();
return false;

}

But when the service is running within the Tomcat it does not work, can anyone help me?
