Silverlight Component

Hi, I am building web based POS terminal. The problem is at the end of billing cycle, need to give print to the receipt printer (that I can do from browser) and also need to open a cash drawer (which can not be done using browser/javascript). I want object built in silverlight that I can use in webbase which will give printer command (some special chars needs to be sent to printer which I'll provide) so that printer will open the cash drawer. The thing is, you need to open the port of printer and send command directly to printer. Here is how you can do it in PHP [login to view URL] but I want it in silverlight so that it runs on client machine and not on server. Need it ASAP as it's quite urgent. Regards, Nayan
