How can differences in printer settings affect the printing of PDF files generated using mpdf in PHP?

Differences in printer settings can affect the printing of PDF files generated using mpdf in PHP by causing formatting issues, such as incorrect page sizes or margins. To solve this issue, you can set specific printer settings within the mpdf configuration to ensure the PDF file is printed correctly on different printers.

// Set printer settings in mpdf configuration
$mpdf = new \Mpdf\Mpdf([
    'mode' => 'utf-8',
    'format' => 'A4',
    'margin_left' => 10,
    'margin_right' => 10,
    'margin_top' => 10,
    'margin_bottom' => 10,
    'margin_header' => 5,
    'margin_footer' => 5,
    'orientation' => 'P'
]);

// Generate PDF content
$mpdf->WriteHTML('Hello, World!');

// Output PDF file
$mpdf->Output('filename.pdf', 'D');
