        $storeID = Mage::app()->getStore()->getId();

        $collection = Mage::getResourceModel('catalog/product_collection')->addAttributeToSelect('*');

        $collection->getSelect()
                   ->joinInner(
                       array('e2' => 'printer_applicable_product'),

    }

        $toolbar = $this->getLayout()->createBlock('catalog/product_list_toolbar', microtime())

        $pager = $this->getLayout()->createBlock('page/html_pager', microtime());
        $toolbar->setChild('product_list_toolbar_pager', $pager);

        $this->setChild('toolbar', $toolbar);
        $this->getProductCollection()->load();

        return $this;
    }

    public function getPagerHtml()
    {
        return $this->getChildHtml('toolbar');
    }
}

app/code/local/HB/Printer/controllers/FinderController.php

class HB_Printer_FinderController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()
    {
        $this->_title($this->__('Products Finder'));     
        $this->loadLayout();     
        $this->renderLayout();

    }

    public function resultAction()
    {
        $this->_title($this->__('Printer Applicable Products'));
        $this->loadLayout();     
        $this->renderLayout();
    }
}

为什么不在当前页面显示消息。如何解决？

【解决方案1】：

您应该通过 Mage_Core_Controller_Varien_Action::_initLayoutMessages() 来初始化所需的布局消息

例子：

public function resultAction()
{
    $this->_title($this->__('Printer Applicable Products'));
    $this
        ->loadLayout()
        ->_initLayoutMessages('checkout/session')
        ->_initLayoutMessages('catalog/session')
    $this->renderLayout();
}

您需要初始化一个包含所需消息的会话模型。

还要记住 printer/finder/result.phtml 应该包含

$this->getMessagesBlock()->getGroupedHtml()
