TCPDF no footer on page if condition is met?

Question

I am trying to set a conditional statement where a footer is set or not.

    if($data['voucher']===0){
        $pdf->setPrintHeader(false);
        $pdf->setPrintFooter(false);
        $pdf->AddPage();
        $pdf->SetXY(0, 10);

        $pdf->create_invoice();
    }
    //CUSTOM CONTENT
    //END 
    $pdf->setPrintHeader(true);
    $pdf->setPrintFooter(true);

But the footer is still set. However if I set

$pdf->setPrintHeader(true);

the header is set but footer doesn't react.

The Header() and the Footer() functions - are defined in an extended class.

Headers and footers aren't printed until the page is ended, which is normally called when you add a new page with Addpage(); So you should end the page manually and then turn headers/footers back on.

 if($data['voucher']===0){

            $pdf->AddPage();
            $pdf->setPrintHeader(false);
            $pdf->setPrintFooter(false);
            $pdf->SetXY(0, 10);

            $pdf->create_invoice();


            $pdf->Endpage();  //END THE PAGE AND TURN HEADERS/FOOTERS BACK ON
            $pdf->setPrintHeader(true);
            $pdf->setPrintFooter(true);
        }
        //CUSTOM CONTENT
        //END 
        $pdf->Addpage(); // Any new page created now will again have headers footers
