bulk pdf generation with html2pdf in codeigniter - php

Question

I am using HTML2PDF library in codeigniter.I am trying to generate bulk pdf using it.
In which i am facing issue like same content in every pdf or pdf have no content.I have already did my homework.Yeah but there is always showing perfect for generated first pdf (For account :3)
As per me there is must be issue of below code :
ob_start();
require_once($template_config.'template.php'); //
$content = ob_get_contents();
ob_clean();
Issue : It works for first time but for second time it flush all the content of content variable and due to that duplicate PDF or without content PDF generate.
I have tried like below
1) create object in generatetemplate.php and pass to common.php
2) tried with include_once //getting same conent in every pdf and if i am doing echo then showing no content for 2nd and 3rd pdf
File structure :
application
controllers
generatetemplate.php
libraries
common.php
html2pdf
html2pdf.php
template.php
common.php :
function print_content($customerdata){
$this->load->library('/html2pdf/html2pdf');
$template_config=$this->config->item('template');
ob_start();
require_once($template_config.'template.php'); //
$content = ob_get_contents();
ob_clean();
$content = str_replace("<CUSTOMER_ADDRESS>",$CUSTOMER_ADDRESS,$content);
$this->CI->html2pdf->pdf->SetDisplayMode('fullpage');
$this->CI->html2pdf->writeHTML($content);
$this->CI->html2pdf->Output($download_path,"F");
}
generatetemplate.php
function __construct() {
parent::__construct();
$this->load->library("common");
$this->load->library('html2pdf');
}
function get_customer_data(){
$this->db->order_by("id","DESC");
$this->db->where('id IN (1,2,3)');
$query = $this->db->get("customers")->result_array();
foreach($query as $key=>$accountdata){
$this->common->print_content($accountdata);
}
}
Any help and ideas will be appreciated.

I have tried below code and its work for me.
Common.php
function print_content($customerdata){
$this->load->library('/html2pdf/html2pdf');
$template_config=$this->config->item('template');
ob_start();
require_once($template_config.'template.php'); //
$content = ob_get_contents();
ob_clean();
$content = str_replace("<CUSTOMER_ADDRESS>",$CUSTOMER_ADDRESS,$content);
$this->CI->html2pdf = new HTML2PDF('P','A4','en'); // Just added this line and its work for me.
$this->CI->html2pdf->pdf->SetDisplayMode('fullpage');
$this->CI->html2pdf->writeHTML($content);
$this->CI->html2pdf->Output($download_path,"F");
}
