Dispose not working correctly

[xZeroKooLx]

Im using BasePrinter to print to a Epson epson tm-t82ii over a networked connection. The issue I'm facing though is that printer.Dispose(); does not seem to be full disposing of the connection. once i print using the following code no other applications or devices can send data to the printer until i close my application.

`private void PrintNumbers() { bool monitor = true; if (printer == null) printer = new NetworkPrinter(settings: new NetworkPrinterSettings() { ConnectionString = $"{targetAddress}:{targetPort}" });

    e = new EPSON();
    // Convert the bitmap to a byte array
    using (var ms = new MemoryStream())
    {
        bmp.Save(ms, ImageFormat.Png);
        byte[] img = ms.ToArray();
        // Print the image
        Setup(monitor);
        //printer?.Write(e.FeedLines(1));
        printer?.Write(e.CenterAlign());
        printer?.Write(e.PrintLine(customMsgRTextBox.Text));
        printer?.Write(e.FeedLines(1));
        printer?.Write(e.SetStyles(PrintStyle.Bold | PrintStyle.FontB | PrintStyle.DoubleHeight | PrintStyle.DoubleWidth));
        printer?.Write(e.PrintLine("YOUR LUCKY NUMBERS ARE:"));
        printer?.Write(e.FeedLines(1));
        printer?.Write(e.PrintImage(img, true, true, 350, 1100));
        printer?.Write(e.SetStyles(PrintStyle.None));
        printer?.Write(e.FeedLines(1))
        printer?.Write(e.FeedLines(1));
        printer?.Write(e.PrintLine("Thanks for visiting The Telegraph Gunning."));
        printer?.Write(e.PrintLine(DateTime.Now.ToString("dd/MM/yy hh:mm:ss tt")));
        printer?.Write(e.FeedLines(3));
        printer?.Write(e.FullCut());
        printer?.Dispose();
    }
}`

Have you tried using a using block to dispose of the printer instead of calling Dispose yourself? Could you put together a minimal reproduction that causes the issue?

Closing for staleness, let me know if you have a chance to reproduce this and we can reopen the issue. I haven't seen this issue before, so I don't have a reproducible example to investigate.
