I have look for a way to print shipping labels for FLat Rate Shipment Method but unable to find one . I tried extension cubex Address label Extension but its not working and giving me error
Fatal error: Class 'Cubix_AddressLabel_Block_Adminhtml_System_Config_Form_Fieldset_Modules_AddressLabel' not found in /home4/user/public_html/demo/app/code/core/Mage/Core/Model/Layout.php on line 590
Is there any other way ?
