Disable filter in a custom column in sales order grid

Question

I am using layout handles in adding custom column to my Orders grid. How can i disable the filtering input field?

Here is my code: app/design/adminhtml/default/default/layout/company

<?xml version="1.0"?>
<layout>
<sales_order_grid_update_handle>
    <reference name="sales_order.grid">
        <action method="addColumnAfter">
            <columnId>printed</columnId>
            <arguments>
                <header>Printed</header>
                <index>printed</index>
                <width>80</width>
                <renderer>Company_myModule_Block_Adminhtml_Sales_Order_Renderer_Printed</renderer>
                <type>text</type>
            </arguments>
            <after>status</after>
        </action>
    </reference>
</sales_order_grid_update_handle>
<adminhtml_sales_order_grid>
    <!-- apply layout handle defined above -->
    <update handle="sales_order_grid_update_handle" />
</adminhtml_sales_order_grid>
<adminhtml_sales_order_index>
    <!-- apply layout handle defined above -->
    <update handle="sales_order_grid_update_handle" />
</adminhtml_sales_order_index>
</layout>

    /**

    $readConnection = $resource->getConnection('core_read');

    /**

     */
    $table = $resource->getTableName('orderprint/orderprint');


    $query = 'SELECT orderprint_id FROM ' . $table . ' WHERE order_id = '
             . $value . ' LIMIT 1';

    /**
     * Execute the query and store the result in $sku
     */
    $value = $readConnection->fetchOne($query);
    //return $value;


    if($value) {return '<span style="font-weight:bold;">Yes</span>';}
    else {return '<span style="color:#900; font-weight:bold;">No</span>';}
    ///return '<span style="color:#900;">'.$value.'</span>';
    }
}
