具有绝对定位的HTML到PDF

Question

I need to generate a PDF, which the user will print on a Specific form, so I have positioned the data in a way that the form will be filled in a proper way after printing.

As of now I have used absolute positioning like

<div class="page_container">
    <div class="first_name">
       John Smith
    </div>
</div>

The style is

.page_container {
    position:relative;
}

.page_container .first_name {
    position:absolute;
    left:50px;
    top:110px;
}

But I could not achieve the positioning in the generated PDF. I have tried with TCPDF and mPDF so far.

My question would be, is there any html to pdf library available to support the above code, else what could be the best alternative to achieve my requirement.

Additional Info: I develop this on Symfony2, I am also ready to use a core php library.
