NewLeaf is a Dyalog APL namespace which turns arrays of data into smart reports. These can be printed, previewed on screen or saved in Adobe's Portable Document Format (PDF) for electronic distribution. It has been developed over many years with constant input from customers, and there can be very few things that APLers want that it cannot easily produce.

The kind of thing you might want to generate in bulk would be a 'letter to shareholders' such as:

Sales Report from NewLeaf

This has a table of figures (which might be specific to the letter), an embedded chart (from RainPro, of course) and a bitmap of the charman's signature. If you just want a fast print of some large tables, NewLeaf again makes life very easy:

A 4-page report from a matrix of text and numbers

This took all of 14 lines of code to produce, and several of those were comments! Of course it would probably take a lot more code than this to assemble the data in the first place.
