A finishing assembly suited to use in a printing system includes a plurality of finishing modules, each of which performs a finishing function. The plurality of finishing modules includes a compiler module which compiles sheets into a set of sheets and at least one stacker module, downstream of the compiler module, which is configured for receiving compiled sets of sheets compiled by the compiler module and stacking a plurality of the sets of sheets into a stack. Optionally, at least one sheet processing module is intermediate the compiler module and the stacker module and receives a compiled set of sheets compiled by the compiler module and processes the compiled set of sheets.
