            'onclick'   => 'jsfunction(this.id)',
            'class'     => 'go'

You just need to use "sales" helper, instead of "xxx". Use below code, it will help to fix this out.

app/local/FirstGood/PrintCard/Block/Adminhtml/Sales/Order/View.php

<?
class FirstGood_PrintCard_Block_Adminhtml_Sales_Order_View extends Mage_Adminhtml_Block_Sales_Order_View {
    public function  __construct() {

       parent::__construct();
       $this->addButton('button_id', array(
        'label'     => Mage::helper('sales')->__('Some action'),
        'onclick'   => 'jsfunction(this.id)',
        'class'     => 'go'
       ), 0, 100, 'header', 'header');
    }
}
