Hi there! Sorry to hear the KODAK STEP Prints app crashes when you click the print button. Let's get to the bottom of this. To help me understand better, could you please tell me:

- Have you tried restarting the app or your Mac?
- Did the app ever work fine on your macOS 10.15.7 before, or is this happening from the start?
- Is your KODAK STEP printer properly connected to your macOS device (via Bluetooth or USB)?
- Are you using the latest version of the KODAK STEP Prints app from the App Store?

While you check on that, here’s a simple step-by-step you can try:

1. Restart the App and Mac
Quit the KODAK STEP Prints app completely. Then restart your Mac. Sometimes this clears temporary glitches.

2. Check App Updates
Open the App Store, go to Updates, and make sure the app is the latest version available.

3. Reinstall the App
If you haven’t already, uninstall and reinstall the app to fix possible corrupted files.

4. Printer Connectivity Check
Make sure your printer is turned on and connected properly. For Bluetooth printers, verify your Mac’s Bluetooth is on and paired with the printer.

5. Paper and Cartridge Check
Make sure there is enough photo paper loaded and that the cartridge is properly inserted in the printer.

If after these steps the app still crashes when printing, let me know—and we can dig deeper, such as checking app permissions, error logs, or possibly resetting the printer device itself.

Would you like guidance on any of the steps above? Also, please share if the problem started recently or after any particular change.
