include("PrintSendLPR.php");

$lpr = new PrintSendLPR(); 
$lpr->setHost("10.0.0.17"); //Put your printer IP here 
$lpr->setData("C:\\wampp2\\htdocs\\print\\test.txt"); //Path to file, OR string to print.

$lpr->printJob("someQueue"); //If your printer has a built-in printserver, it might just accept anything as a queue name.
?>
