What are some potential challenges when printing PDF files from a local network using PHP?

One potential challenge when printing PDF files from a local network using PHP is ensuring that the correct printer is selected for printing. This can be achieved by specifying the printer name or IP address in the PHP code before sending the print job. Additionally, ensuring that the PDF file is accessible from the local network and that the necessary permissions are set for printing can also be a challenge. 

$printerName = 'PrinterName'; // Replace 'PrinterName' with the actual name of the printer
$filePath = 'path/to/pdf/file.pdf'; // Replace 'path/to/pdf/file.pdf' with the actual path to the PDF file

// Send print job to the specified printer
exec("lp -d $printerName $filePath");
