Yes, otherwise how you going to connect to it? But you do not need a
computer.
Several options
1. You can buy a print server (they cost $20-$50)separatelly from printer
but then you will additional box and AC adapter. Or you can by the one that
is very small and do not need power (it takes it from printer port).

2. You can buy printer with already built in network interface.

I suggest a small compact printer with print server port (sometimes called
ZEBRANET).
Like this one Zebra TLP2844
http://www.systemid.com/barcode_printers/zebra_tlp2844.asp
Those printers support EPL or ZPL language. It's a simple language and
you do not need a driver for it.
Your ASP.NET application simply sends data via TCP/IP and printer
prints....
No need to have computer on a kitchen. And you do not need separate exe
running in background..
You do not need a driver for those printers. They use EPL language which
is very easy language.
you basically send it commands like ^PO10,20^FSMy Name^XA
And it will print My Name position (10,20)
Below is the code to send bytes to TCP/IP printer.
George
public bool SendBytesToPrinter(byte[] p)
{
try
{
IPEndPoint ipEndPoint;
ipEndPoint = new IPEndPoint(IPAddress.Parse(_sName), 9100);
Socket socket;
using (socket = new Socket(
AddressFamily.InterNetwork,
SocketType.Stream,
ProtocolType.Tcp
))
{
socket.Connect(ipEndPoint);
socket.Send(p);
socket.Close();
}
return true;
}
catch (Exception e)
{
//TODO: do something with exception
return false;
}
}

Hi, I finished a asp.net restaurant/bar system, but when the waiter
clicks "send itens" on IE palmtop, it needs to send the itens to a
printer wich will be on the kitchen... What is the best approach doing
that? The pc on kitchen should have a exe running in background that
listens the itens wich arrives on the database and prints it?
What you suggest? Thanks!
