Looking into the stack trace, the problem seems that your code is 
infinetly recurse:

SolapaServicioImpresion..ctor -> calls EnumeratePrinters -> calls 
solapaServicioImpresion..ctor-> calls EnumeratePrinters -> ....

You can also see that gtk_enumerate_printers was already called earlier. 
No idea why you get the EntryPointNotFoundException, but I suspect it to 
be related  to the recursion issue. This is for sure not a problem in Gtk#.
