What are some common issues when printing PDF files on dot matrix printers and how can PHP be used to address them?

Issue: One common issue when printing PDF files on dot matrix printers is that the formatting may not be preserved correctly, leading to misaligned text or missing characters. This can be addressed by converting the PDF file to a plain text format before sending it to the printer. PHP Solution: 

// Path to the PDF file
$pdfFile = 'example.pdf';

// Use PDF to text conversion tool (like pdftotext) to convert PDF to plain text
exec("pdftotext $pdfFile");

// Read the converted text file
$textFile = 'example.txt';
$text = file_get_contents($textFile);

// Send the plain text to the dot matrix printer
$printer = fopen('php://output', 'w');
fwrite($printer, $text);
fclose($printer);

// Remove the temporary text file
unlink($textFile);
