What are the potential pitfalls of using virtual PDF printers like FreePDF or PDFCreator in PHP?

Potential pitfalls of using virtual PDF printers like FreePDF or PDFCreator in PHP include compatibility issues with different operating systems, dependency on third-party software, and limited customization options. To mitigate these risks, consider using a PHP library like TCPDF or FPDF to directly generate PDF files without relying on external tools.

// Example using TCPDF library to generate a PDF file
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', 'B', 16);
$pdf->Cell(0, 10, 'Hello World', 0, 1, 'C');
$pdf->Output('example.pdf', 'D');
