List & Label tries to load the export extension module cmll29ex.llx from the main DLLs path by default. All export formats are thus automatically available when passing LL_PRINT_EXPORT as target to LlPrint(WithBox)Start.
If you want to deactivate the export modules, use LL_OPTIONSTR_LLXPATHLIST and pass the file name preceded by a ^, i.e. "^cmll29ex.llx". The same option may be used to load the module from a different path.
If you want to load the export modules from a different directory, you should also use this option. For example, you can use "c:\programs\<your application>\cmll29ex.llx, to load the export modules from your application directory.
