Thanks! The issue is not PDF generation per se. The only bottleneck is the charts, they are rendered on CANVAS element directly. The charts are mainly sparklines and line chart. Replacing them will be a non-trivial task. Your suggestion of converting HTML -> PDF is a great one but then again the rendered HTML will require static charts (as GIF or JPG). I will probably go down this route: Screenshot of Report -> Image -> PDF. Inefficient, yes. Heavy file, yes. But it will work :)
