Generate invoices, statements and reports on the server, at volume

The problem

Documents are generated by rendering HTML in a headless browser, or by a print server nobody wants to own. Both are heavy, both fail in ways that are hard to reproduce, and both put a moving part between a business event and a PDF that has to be right.

The approach

Call the engine in-process from the service that already has the data. Compose the page directly, or fill a template you keep under version control. There is no separate service to scale, no font that renders differently on the build machine, and nothing to license per document.

How you can check it

The same code path is exercised by the worked examples in this SDK for every server-side language it supports, and the output is byte-comparable across platforms because there is one engine underneath all of them.
