Changing tables/box in invoice pdf file

Hi,

I would like to hide table header and border in invoice print file (pdf). And also would like to hide “invoice” text which I marked in the attached image.

Plaese check enclosed image

Pièces jointes :

Home -> Setup -> Display

Best regards

Thank you Casati for your reply.

I could not enclosed to image as an attachment. So I think I didn’t correctly state my question.

But I find what I need;

File name : pdf_crabe.modules.php in core/modules/facture/doc
I disabled below code

[code]
$this->_tableau($pdf, $tab_top, $this->page_hauteur - $tab_top - $heightforinfotot - $heightforfreetext - $heightforfooter, 0, $outputlangs, 0, 0);[/code
