I am not an expert, but I believe the Dear Jane software is standalone. That is, you don't need EQ5 or EQ6 in order to print out blocks. Owners of EQ5 or EQ6 may purchase Dear Jane as an add-on.
Here is a link to a description of Dear Jane:

Also, I noticed Amazon has some reviews of it. You might find additional information about it there.
