    I have a question about Sockets and Asyncstreams...

    I'm using sockets to talk directly to port 9100 on a thermal receipt printer. It works great but I can only establish a 1 to 1 relationship. I'd like to have multiple tablets print to the same printer. The printer has multi-session enabled so I can print from multiple tablets (if I close the session). The problem is that I need to disconnect from the first tablet before the second will start printing.

    So my question is how can I tell that my stream has completed to know to disconnect? I'm using this to write to the stream:

    Dim ReceiptBuffer() As Byte
    ReceiptBuffer = s.GetBytes(
    Is there an event that says that the buffer is empty?

    There is no "complete" event. I guess that the printer doesn't send any result back, right?

    You can always use a timer and close the connection after a few seconds.
