Call an .exe from Silverlight

Hi everybody,

I have a small "issue" in my Web Browser Application. I need print in default printer without asking to the user. To do that I found a way: convert my web Browser application into a Trusted application and it works, the problem is that due to company policies i can't distribute the certificate in all the client machines, so, my problem still continues.Iwasthinking of creatingan application in .Net  andit wasthis applicationwhichinvokeaprint function so my question is: Can I call an .exe from my Silverlight application??the application .exe would be executedlocally,i.eon the client machine

Thanks in advance
