auto=1立即PRINT，否则timeOut毫秒后PRINT，如printPage(0,5000)；


function printPage($auto=1,$timeOut=10000) {
if ($auto == 1) {
echo "
< SCRIPT LANGUAGE="JavaScript" >
< !-- Begin
if (window.print) {
window.print();
}
else {
alert('No printer driver in your PC');
}
// End -- >
< /script >
n";
}
else {
echo "
< SCRIPT LANGUAGE="JavaScript" >

< !-- Begin
if (window.print) {
setTimeout('printCheck()','$timeOut');
}
else {
alert('No printer driver in your PC');
}
function printCheck() {
agree = confirm('OK to print now?');
if (agree) window.print();
}
// End -- >
< /script >
n";
