You can print any part of fuseki/joseki tree from any database (Full, professional etc).

Open fuseki/joseki window and place position from which you want start variation subtree print.
Set Page Setup->General->Diagram Type to Variation.
Set Page Setup->General->To Move Number to the number where variation subtree finish.
Set Page Setup->General->Max Number of diagrams to big number (for example 100).
Set diagram size and other options in Page Setup->Diagrams.
