mPDF document auto height (POS printer)

Question

I\'m trying to create a PDF file using mPDF class and I need it to auto-height my document and not create blank spaces at bottom.

Here\'s two images of two different gen

Answer 1

Solved.

I had one issue in my code that was creating that amount of space and it was on CSS structure.

body { font-size: 80% }

And changing to 100% solved the blank space, but I also look into the mPDF class and I found the _setPageSize() function.

public function write($html, $url)
{   
    /*
     * Writing and remove the content, allows the setAutoTopMargin to work
     *
     * http://www.mpdf1.com/forum/discussion/621/margin-top-problems/p1
     */
    $this->mPDF->WriteHTML($html[0]);
    $this->mPDF->page   = 0;
    $this->mPDF->state  = 0;
    unset($this->mPDF->pages[0]);
    
    // The $p needs to be passed by reference
    $p = 'P';
    $this->mPDF->_setPageSize(array(56, $this->mPDF->y), $p);

    foreach($html as $content)
    {
        $this->mPDF->addPage();
        $this->mPDF->WriteHTML($content);
    }

    $this->mPDF->Output($url);
}
