Hi there! I understand that you're experiencing a printer connection issue with Coloring Games, including apps like Coloring Book, Painting, and Glow Draw. Let’s dive in and see if we can resolve this together.

To start, could you let me know the type of printer you’re using and how it’s currently connected to your computer? Is it a wired connection or wireless? Additionally, are there any specific error messages you're seeing apart from "No connection to printer"?

Once I have a bit more information, I can guide you through some troubleshooting steps!

Brother DCP L2550DW. Wireless Nothing but the message above

Thank you for the details! Since your Brother DCP L2550DW is wireless and showing a "No connection to printer" message, let's go through some troubleshooting steps to get it reconnected.

### Step 1: Verify Printer Status
1. Check Power: Make sure your printer is turned on and there are no blinking lights or error messages indicating a different problem.
2. Wireless Status: Ensure that your printer is connected to the same Wi-Fi network as your computer. You can often check this on the printer's display.

### Step 2: Restart Devices
Sometimes, a simple restart can resolve connectivity issues:
1. Restart the Printer: Turn off the printer, wait for about 10 seconds, and then turn it back on.
2. Restart your Computer: Restarting can help refresh the connection.

### Step 3: Check Wireless Connection
1. Full Wi-Fi Connection: Make sure your Wi-Fi is functioning properly. You can try connecting another device (like your smartphone) to the Wi-Fi and see if it connects.
2. Reestablish Connection: If the printer is not connected to Wi-Fi, refer to your printer’s manual or follow these steps:
- On the printer's control panel, navigate to "Network" settings.
- Select "Wireless Setup Wizard" and follow the prompts to reconnect your printer to Wi-Fi.

### Step 4: Update Drivers and Software
Make sure that the drivers for your Brother printer are installed and up-to-date:
1. Go to the Brother support website and download the latest drivers installed for your printer model.

### Step 5: Check Router Settings
If you're still having issues, it might be a good idea to check your router settings, such as authentication methods, to ensure they're compatible with the printer. Sometimes, changing the security settings to 'WPA2/WPA3-Personal' may help (source).
