What are some best practices for handling client-side printing requests in a PHP application?

When handling client-side printing requests in a PHP application, it's important to ensure that the content being printed is properly formatted for printing and that the appropriate headers are set to trigger the print dialog. One common approach is to use CSS media queries to define styles specifically for printing. 

<?php
// Check if the print parameter is set in the URL
if(isset($_GET['print'])) {
    // Set appropriate headers to trigger the print dialog
    header("Content-type: application/pdf");
    header("Content-Disposition: inline; filename=print.pdf");
    
    // Output the content to be printed
    echo "<html><head><title>Print</title><link rel='stylesheet' type='text/css' href='print.css' media='print'></head><body>";
    echo "<h1>Printed Content</h1>";
    echo "<p>This is the content to be printed.</p>";
    echo "</body></html>";
    exit;
}
?>
