Q:

Remove Tax from PDF Invoice (HELP!)

I've been searching around and struggling to find a conclusive answer to this.
I've followed the steps mentioned here:
http://nsmchami.wordpress.com/2014/03/15/magento-remove-tax-from-invoice/
Which has removed the "Tax" header in the column, but it's still displaying the price, like so:

So the question is how can I remove this price from the Invoice PDF? 
Any help will be hugely appreciated.

A:

Rewrite the model Mage_Sales_Model_Order_Pdf_Items_Invoice_Default and remove this
    // draw Tax
    $lines[0][] = array(
        'text'  => $order->formatPriceTxt($item->getTaxAmount()),
        'feed'  => 495,
        'font'  => 'bold',
        'align' => 'right'
    );

the model Mage_Bundle_Model_Sales_Order_Pdf_Items_Invoice and remove this:  
            $tax = $order->formatPriceTxt($_item->getTaxAmount());
            $line[] = array(
                'text'  => $tax,
                'feed'  => 495,
                'font'  => 'bold',
                'align' => 'right'
            );

and the model Mage_Downloadable_Model_Sales_Order_Pdf_Items_Invoice and remove this 
    // draw Tax
    $lines[0][] = array(
        'text'  => $order->formatPriceTxt($item->getTaxAmount()),
        'feed'  => 495,
        'font'  => 'bold',
        'align' => 'right'
    );
