Return pdf instance on Controller

use Magento\Framework\App\Action\Action;
use Staempfli\Pdf\Model\View\PdfResult;
use Staempfli\Pdf\Service\PdfOptions;

class GeneratePdf extends Action
{
	public function execute()
	{
    	return $this->renderPdfResult();
	}

	protected function renderPdfResult()
	{
    	/** @var PdfResult $result */
    	$result = $this->resultFactory->create(PdfResult::TYPE);
    	$result->addGlobalOptions(
      	  new PdfOptions(
         	   [
         	       PdfOptions::KEY_GLOBAL_TITLE => __('Return PDF'),
         	       PdfOptions::KEY_PAGE_ENCODING => PdfOptions::ENCODING_UTF_8,
         	       PdfOptions::KEY_GLOBAL_ORIENTATION => PdfOptions::ORIENTATION_PORTRAIT,
         	       PdfOptions::FLAG_PAGE_PRINT_MEDIA_TYPE,
         	   ]
        	)
    	);
    	$result->addPageOptions(
      	  new PdfOptions(
         	   [
         	       PdfOptions::KEY_PAGE_COOKIES => ${'_COOKIE'},
         	   ]
        	)
    	);
    	return $result;
	}
}

Header and Footer

Header and footer html can be added as follows:

Create your header.html and footer.html files inside your Module template dir

<!doctype html>
<!-- app/code/Vendor/Package/view/frontend/templates/pdf/header.html -->
<html>
	<body>
		Header text
    	</body>
</html>

<!doctype html>
<!-- app/code/Vendor/Package/view/frontend/templates/pdf/footer.html -->
<html>
		<body>
		Footer text
		</body>
</html>

Attach those files to the Controller pdf generation

<?php
namespace Vendor\Package\Controller\Actions;

use Magento\Framework\App\Action\Action;
use Magento\Framework\View\Element\Template\File\Resolver as TemplateResolver;
use Staempfli\Pdf\Model\View\PdfResult;
use Staempfli\Pdf\Service\PdfOptions;

class GeneratePdf extends Action
{
    /**
 	     * @var TemplateResolver
	     */
	    private $templateResolver;

	    public function __construct(
    	TemplateResolver $templateResolver,
    	Context $context
	    ) {
   	        parent::__construct($context);
	$this->templateResolver = $templateResolver;
	    }

        public function execute()
	    {
            return $this->renderPdfResult();
	    }

	    protected function renderPdfResult()
	    {
    	/** @var PdfResult $result */
    	$result = $this->resultFactory->create(PdfResult::TYPE);
    	$result->addGlobalOptions(
      	  new PdfOptions(
         	   [
         	       PdfOptions::KEY_GLOBAL_TITLE => __('Return PDF'),
         	       PdfOptions::KEY_PAGE_ENCODING => PdfOptions::ENCODING_UTF_8,
         	       PdfOptions::KEY_GLOBAL_ORIENTATION => PdfOptions::ORIENTATION_PORTRAIT,
         	       PdfOptions::FLAG_PAGE_PRINT_MEDIA_TYPE,
         	       PdfOptions::KEY_PAGE_HEADER_SPACING => "10",
         	   ]
        	)
    	);
    	$result->addPageOptions(
      	  new PdfOptions(
         	   [
         	       PdfOptions::KEY_PAGE_COOKIES => ${'_COOKIE'},
         	       PdfOptions::KEY_PAGE_HEADER_HTML_URL => $this->templateResolver
                    ->getTemplateFileName('Vendor_Package::pdf/header.html'),
                PdfOptions::KEY_PAGE_FOOTER_HTML_URL => $this->templateResolver
                    ->getTemplateFileName('Vendor_ Package::pdf/footer.html'),
         	   ]
        	)
    	);
    	return $result;
	    }
}

NOTE: Only the header or only the footer as html is not possible, either both or none. Otherwise top and bottom margins are ignored.

Troubleshooting

wkhtmltopdf should not be installed via apt-get. See:
- http://stackoverflow.com/questions/18758589/wkhtmltopdf-installation-error-on-ubuntu

Tiny or very small output on Mac:

It seems to be a bug on wkhtmltopdf version 0.12.4. It can be fixed by installing 0.12.3
