hi phrasespot,
the prestashop version is 1.3.7.0
i did not modify anything. in the PDF.php are some lines commented out, but i don't think it has to do with the problem.
line 485 - 486
/* $pdf->Cell($width, 0, self::l('Total products (tax excl.)').' : ', 0, 0, 'R');
$pdf->Cell(0, 0, (self::$orderSlip ? '-' : '').self::convertSign(Tools::displayPrice($priceBreakDown['totalProductsWithoutTax'], self::$currency, true, false)), 0, 0, 'R');*/
line 537-538
/* $pdf->Cell($width, 0, self::l('Total').' '.(self::$_priceDisplayMethod == PS_TAX_EXC ? self::l(' (tax excl.)') : self::l(' (tax incl.)')).' : ', 0, 0, 'R');
$pdf->Cell(0, 0, (self::$orderSlip ? '-' : '').self::convertSign(Tools::displayPrice((self::$_priceDisplayMethod == PS_TAX_EXC ? $priceBreakDown['totalWithoutTax'] : $priceBreakDown['totalWithTax']), self::$currency, true, false)), 0, 0, 'R'); */
