How can PHP be used to automate printing tasks to a specific network printer without displaying a print dialog?

To automate printing tasks to a specific network printer without displaying a print dialog, you can use PHP with the help of the `printer_open()` and `printer_write()` functions. By specifying the printer name and sending the print data directly to the printer, you can achieve this automation without user intervention.

$printer = printer_open("\\\\computer-name\\printer-name");
if($printer){
    $content = "Your content to be printed";
    printer_write($printer, $content);
    printer_close($printer);
} else {
    echo "Failed to connect to printer";
}
