printing and  (5 Views)

I must admit I getting a little bit fed up now but... I want to produce printed output from a vb software.
I have tried printform but this is too limited as u can't exceed the screen resolution of the PC that the software is executing and the results differ b/w XP and vista anyway.
I have tried integrating with word but this is slow and clumsy and if using word simultaneously as executing the application causes spurious results.
I have version 11 of crystal reports that appearantly can't be integrated with visual studio.
I have looked at visual studios report template but I'm afraid I have absolutely no solution where to start with it and can't find any tutorials that assist.
The sorts of reports I need to produce are delivery notes invoices and more...
So I think my difficulty is... what is using to produce printed documents from visual studio 2005 express
