How to print label using zpl QLn220 printer, it's connected to my PC via Bluetooth. I want print function from c#.Net

additional information after comment below
Thanks. I tried and Finally posted question here. Actually my printer is connected via Bluetooth to COM3 standard serial port of my PC. I am trying to open that port using following code

C#

SerialPort sp = new SerialPort();
sp.PortName = "COM4";
sp.BaudRate = 9600;
sp.Parity = Parity.None;
sp.DataBits = 8;
sp.StopBits = StopBits.One;
sp.Handshake = Handshake.RequestToSend;
sp.Open();

while opening the port I am getting following error

"The given port name does not start with COM/com or does not resolve to a valid serial port.Parameter name: portName"

Some people suggested me to change port number I changed from COM3 to COM4 still getting same eeror.

Do you have a printer driver installed for this device? If so you may have to uninstall it.

Reading the error it seems the name you are giving is not matching the correct format or maybe not existant in your system.
Have a look to these links, they might help.

As has been said you need to develop systematic problem solving skills. At the moment you are poking at shadows.
Run this example (already mentioned) then work out how to proceed: http://msdn.microsoft.com/en-us/library/system.io.ports.serialport.getportnames(v=vs.110).aspx

The Zpl printer was connected to Standard Serial port via Bluetooth. I solved it by following this link Printing label and Barcodes using ZPL printer from C#.Net
