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!
