Network Printer

Trying to print to a barcode printer on the network from a WebSphere Server app running on Unix. Following is my print method:

private final void sendToNetworkPrinter(String ipaddress, String port, String printerCommands)
throws JSpaException {

URL printerUrl;
URLConnection printerConnection;

try {
printerConnection = new URL("http://" + ipaddress + ":" + port).openConnection();
printerConnection.setDoOutput(true);

Writer out = new BufferedWriter(new OutputStreamWriter(printerConnection.getOutputStream()));
out.write(printerCommands);
out.close();
} catch....

When I step through the code, I see on a network monitor that the 'getOutputStream()' results in TCP SYN/ACK messages being exchanged between the server and the printer. But, the short ASCII print command string that the 'write()' method should send does not get sent by the server.

Any ideas?
 
I agree. Here's the link: http://aspose.com/file-tools
