[Mono-devel-list] Printing status and reporting engine

Well thanks for your project it is surely needed...

Nowadays I'm using specific code over iTextSharp to generate PDF files
and then exec'ing lpr on them, as my reporting solution.

I don't think anything is actively being developed in the printing classes. 
Neither Gnome-printing is correctly supported by GTK#. 

So that lots of work in the printing support subject is awaiting for
enterprising volunteers...

Could you help us? At least by pointing at bugzilla the not what is
missing (maybe just a task reminding case on the whole subject) but on
how it should be working (some small pieces of code that exercise
things and that work attached to specific cases) so that we can
implement missing things correctly?

Thank you, again

In truth there is but it is tyed to specific languages (and their
additional runtime libraries): VB.NET and JScript.NET that has
late-binding and Boo that has duck-typing allow for some
"Variant"-type functionality. C# is a strict-typing language...

Cool. AFAIK, JScript.NET also has such embedded evaluator. The BOOI
interpreter for the boo language has some pieces that could have been

Yes, I think things are mostly stubbed, not really implemented in that space.

As I said, I know no Report Generating tool for Mono. Some people
already expressed the need in the list, but some want a gigantic first
step, like if a tool as-fully-featured-as Crystal Reports or Microsoft
SQL Server Reporting Services, could be built from scratch in some few

Well I generate PDFs with iTextSharp that is a port of java's iText
(by one of the it's main mantainers). I think it is far from perfect,
but it certainly works.
