What potential pitfalls should be considered when using TCPDF for generating PDFs in PHP?

One potential pitfall when using TCPDF for generating PDFs in PHP is the generation of large PDF files, which can consume a significant amount of memory and potentially lead to performance issues or memory exhaustion. To mitigate this, it is recommended to optimize the content of the PDF, such as reducing image sizes or limiting the amount of data being processed. 

// Example of optimizing PDF generation by reducing image size
$pdf = new TCPDF();
$pdf->setPrintHeader(false);
$pdf->setPrintFooter(false);

// Reduce image size
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);

// Add content to PDF
$pdf->AddPage();
$pdf->SetFont('Arial', '', 12);
$pdf->Cell(0, 10, 'Hello, World!', 0, 1, 'C');

// Output PDF
$pdf->Output('example.pdf', 'I');
