I do not understand too, I haven't isolated it, but later that week I
will try to make an example.
Shortly:
take a project where you are printing, add at <printer>_Begin() event
the Paint.Begin(<printer>), add 'Export' to the Startup and make it a
library.
run as executable it prints fine
Now make a new project that insert the previous project as library ,
call it, and try to print.
