Hi !
Of course, for "Print Request Generation", you need GLM + and WWI Generation server of SP 31 and higher. (Now SP 32 is available). you can check that in service market place.
In short, to use all the features in GLM +, you need wwi generation server(EHS WWI 3.2) with support package 31 or higher and also the WWI Generation servers has to be in Unicode mode.
