    Where can I find more information about this bug as we print to IP network printers and would like to understand how it affects us and how to prioritise getting the bugfix rolled out.

    Thanks

      Our product uses the System.Net.Sockets.TcpClient class of .NET Framework when printing to IP network printers. The TcpClient object gets a System.Net.Sockets.NetworkStream object after connecting to the IP printer in order to use it for sending ZPL or EPL commands. The bug was that internally, we were closing/disposing such stream object early and in some networks that causes the following exception:

      [Cannot access a disposed object. Object name: ‘System.Net.Sockets.Socket’]
