Question:

I’m encountering an issue when trying to connect to a network printer (BC-99AC) using PHP. Here’s the error message I’m receiving:

Cannot initialise NetworkPrintConnector: IP: 192.168.123.100, Port: 9100, Error: Connection timed out, Error Code: 110

I’ve verified that the printer is powered on and connected to the network correctly. Additionally, I’ve checked the IP address (192.168.123.100) and ensured that there are no firewall rules blocking the connection.

Here’s the relevant code snippet:

try {
    $connector = new Mike42EscposPrintConnectorsNetworkPrintConnector("192.168.123.100", 9100);
    $printer = new Mike42EscposPrinter($connector);
    // Other printing logic here...
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}

Despite these checks, I’m still experiencing the connection timeout issue. Can anyone provide guidance on how to troubleshoot and resolve this problem? Are there any additional steps I should take or configurations I should check?

Any help would be greatly appreciated. Thank you!

What did I try:

In attempting to connect to the network printer, I tried the following:

1. Verified that the printer is powered on and connected to the network.
2. Confirmed the IP address (192.168.123.100) and ensured it is correct.
3. Checked for any firewall rules blocking the connection.
4. Used the provided code snippet to establish the connection.

What I expected was that the code would successfully connect to the network printer without encountering any errors. However, despite these checks, I still encountered a connection timeout issue with Error Code 110.

Any insights into why the connection is timing out and how to resolve this issue would be greatly appreciated. Thank you!
