Hi All,
I have a server-wide blazor web application that I've written. Part of the application connects to a printer via a TCP connection and sends a byte array. It works when I run it from my computer, but when it is hosted on the webserver, the connection is stopped after about 128kb of data is transmitted.
Is there a configuration setting in IIS that limits outgoing connections to 128kb? Seeing as the connection (and other TCP connections the application uses) are successfully created and some information gets through, I don't think this is a firewall issue.
Thanks!

If the web application is hosted on the Internet and your printer is on a local network then the printer must be accessible from the internet.
