Batch Printing

First of all, this is a question coming from an older post;

In this earlier post the standard Archi-lab printing node was changed so that the print node accepts a list of printsettings so that a list of sheets could get the appropriate size settings.

One of the functions in this node is to select to combine the sheets into 1 file or seperate files, but this function is broken, it doesn’t work.

How can i get this function to work again so that i can batch print multi-size sheets into 1 file.
Advise would be very welcome.
