What are some common challenges when trying to output a barcode as a file using TCPDF in PHP?

One common challenge when trying to output a barcode as a file using TCPDF in PHP is that the barcode may not be displayed correctly or may not be generated at all. This can be due to incorrect settings or parameters passed to the TCPDF library. To solve this issue, ensure that you are using the correct barcode format and that the necessary libraries are properly included. 

// Include the TCPDF library
require_once('tcpdf/tcpdf.php');

// Create new TCPDF object
$pdf = new TCPDF();

// Add a page
$pdf->AddPage();

// Set barcode format and parameters
$barcodeText = '1234567890';
$barcodeType = 'C39';
$barcodeDisplay = $pdf->write1DBarcode($barcodeText, $barcodeType, '', '', '', 18, 0.4, $style, 'N');

// Output the PDF as a file
$pdf->Output('barcode.pdf', 'F');
