Send Cut Code to Printer VB.NET

I have a Star SP300 (POS) printer. It is installed as a windows printer with Generic Text Only drivers. I'm using RawPrinter Helper Class to send data to the printer. See: <[login to view URL]> . It works correctly printing the text. My only problem is that this printer has an AutoCuter feature (to cut the ticket paper) but to make it work, I have to send a special code to the printer. I tried using the SendStringToPrinter method from the rawprinteerhelper class, but it did not work. Just tell me how to make this printer cut the paper under VB.NET (with the printer installed under windows) and you win the bid. One problem is that this printer is serial (COM1) so, I cannot just open the port and send the data because when it is installed as a printer, the com1 is under exclusive access by windows. I think that a solution would be to use SendBytesToPrinter from Rawprinterhelper class, but I just dont know how this function works.
