I had a few issues with this a while ago, and amongs some of the fixes was this missing font error.
Try to look for 2 lines like these
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
change these 2 line to
$pdf->SetFont('FreeSans', '', 11);
$pdf->setHeaderFont(Array('FreeSans', '', 10));
$pdf->setFooterFont(Array('FreeSans', '', 10));
