In magento admin panel, on invoice view page, we can see there is "print pdf" option.

we want to display "print pdf" on order view page.

Answer 1

you have to loop on the invoice collection of your order (even if you have just one invoice per order, Magento store a 1-* relation).

And for each invoice generate the link.

I let you theme as you want.

$adminHelper = Mage::helper("adminhtml");
foreach ($order->getInvoiceCollection() as $invoice) {
    $printInvoiceUrl = $adminHelper->getUrl('adminhtml/sales_order_invoice/print', array('invoice_id' => $invoice->getId());

    //render your button
}
