I need some help. - Page 1

Hi.
Thank you for this amazing plugin.
This is what I did in main file:
ob_start();
include('ac_order_form.php');
$content = ob_get_clean();

// convert in PDF
require_once('/html2pdf/html2pdf.class.php');
try
{
$html2pdf = new HTML2PDF('P', 'A4', 'fr');
$html2pdf->writeHTML($content, isset($_GET['vuehtml']));
$html2pdf->Output('exemple01.pdf');
}
catch(HTML2PDF_exception $e) {
echo $e;
exit;
}
And in the "ac_order_form.php" file I put these code lines.
<style>
.main_wrapper{
width:816px;
height:1056px;
padding:30px;
border:1px solid black;
}
.column_wrapper{
width:100%;
}
.center_text{
text-align:center;
}
.main_title{
font-size:24px;
font-family:sans;
font-weight:bold;
color:black;
}
.main_description{
font-size:13.33px;
font-weight:400;
font-family:sans;
color:black;
}
.main_label{
font-size:11.58px;
font-weight:400;
font-family:sans;
color:black;
line-height:11.58px;
}
</style>
<page style="font-size: 10pt">

But "TCPDF ERROR: Could not include font definition file: sans" is occured and I am stuck.
A little help?
Thank you very much.

The name of the font is probably not "sans", but "dejavusans".

If you use that font through the document you could omit it in the style declarations and add:

$html2pdf->setDefaultFont('dejavusans');

Thank you for your service.
I've fixed the font problem but faced another problem.
"TCPDF ERROR: Some data has already been output, can't send PDF file"
Please help me one more.
Regards.

Try to comment out the two lines with images:
<img src="img.png" style="float:left;"/>
<img src="img.png" style="float:right;"/>

Are all the tags closed correctly?

Difficult to answer - searching Google for "TCPDF ERROR: Some data has already been output, can't send PDF file"
gives 25000 results.

You should check the HTTP headers, or maybe it's because of a BOM if your source code is written in utf8? (http://stackoverflow.com/questions/13702522/utf-8-bom-and-headers-in-php)

Cómo puedo hacer para que las tablas que aparecen en el pdf generado aparezcan centradas, utilizo el HTML2PDF??
Ayuda, por favor!
