Are there best practices for establishing a connection between a tablet and a network printer for printing PDF files in PHP?

To establish a connection between a tablet and a network printer for printing PDF files in PHP, you can use the PHP `printer_open()` function to connect to the network printer and then use a library like TCPDF to generate and print the PDF file. Make sure the tablet is connected to the same network as the printer for successful printing.

$printer = printer_open("\\\\network_printer_ip_address\\printer_name");
if ($printer) {
    $pdf = new TCPDF();
    // Generate your PDF content here
    $pdfContent = $pdf->Output('filename.pdf', 'S');
    
    printer_start_doc($printer, "Document");
    printer_start_page($printer);
    printer_set_option($printer, PRINTER_MODE, "RAW");
    printer_write($printer, $pdfContent);
    printer_end_page($printer);
    printer_end_doc($printer);
    printer_close($printer);
} else {
    echo "Failed to connect to printer.";
}
