Answer 1

you can use tcpdf to render pdf from html. it provides more flexibility
https://tcpdf.org/examples/
see this code, this will generate dummy invoice.
<?php
function generateInvoice(){
$invoice_no = 0001;
require_once('tcpdf/tcpdf.php');
class MYPDF extends TCPDF
{
public function Header() {
}
// Page footer
public function Footer() {
// Position at 15 mm from bottom
$this->SetY(-15);
// Set font
$this->SetFont('helvetica', 'I', 12);
}
}
// create new PDF document
$pdf = new MYPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set header and footer fonts
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
// set margins
$pdf->SetMargins(0, 0, 0);
$pdf->SetHeaderMargin(0);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
// set auto page breaks
$pdf->SetAutoPageBreak(True, 0);
// set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
// set some language-dependent strings (optional)
if (#file_exists(dirname(__FILE__).'/lang/eng.php')) {
require_once(dirname(__FILE__).'/lang/eng.php');
$pdf->setLanguageArray($l);
}
// ---------------------------------------------------------
//set custom font
//$fontname = TCPDF_FONTS::addTTFfont('OpenSans-Semibold.ttf', 'TrueTypeUnicode', '',12);
// use the font
$pdf->SetFont($fontname, '', 12, '', false);
// add a page
$pdf->AddPage();
$pdf->setFontSize(40);
$pdf->Write(0, 'Company', '', 0, 'C', true, 0, false, false, 0);
$pdf->setFontSize(12);
$y = $pdf->getY();
$pdf->writeHTMLCell(100, 90, '18', $y+10, '<table cellspacing="0" style="background:#000;" cellpadding="1">
