I have a Star Micronics 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: http://support.microsoft.com/?id=322090
. 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 (VB.NET), but it did not work.

I need to make this printer cut the paper under VB.NET (with
the printer installed under windows).

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. And also the
OPOS driver that has a function to send the cut command does not work
if the printer is installed in windows.

I think that a solution would be to use SendBytesToPrinter from
Rawprinterhelper class, but I just dont know how this function works.

Hello, 


It might be like Epson Auto-Cutter, in Epson TM88IIP, if I am not
wrong you can use ESC c 14(ASCII) or 1B 63 31 4 (HEX) to cut the
paper.

1 - You can also send the commands directly to the printer, as if you
were opening a file.

2 - The printer also might have a property with auto-cutter depending
on the paper style. This can be defined in the Control Panel, on the
printer properties.
