Add to your arguments the filter argument with false value:

<arguments>
            <header>Printed</header>
            <index>printed</index>
            <width>80</width>
            <renderer>Company_myModule_Block_Adminhtml_Sales_Order_Renderer_Printed</renderer>
            <type>text</type>
            <filter>false</filter>
</arguments>
