Printing a report in a shared printer

Question

Hi,

I´m trying to print a report and I´m using a PrintOptions to catch all printers in the network with the Printers.InstalledPrinters method. But I can´t catch the shared printers, only the local printers. 

Somebody knows other method to catch all local, shared printers of network. 
This aplication is web, not windows form.
