If you’re experiencing image print quality issues with the Kodak Photo Printer app, there are several key troubleshooting steps you should follow to address the most common causes:

1. Check Original Photo Quality
- Low-resolution images can result in poor print quality. Kodak recommends using photos with at least 1280x2448 pixels to ensure sharp prints6.

2. Update and Reinstall Printer App
- Make sure you are using the correct and updated “KODAK Photo Printer” app from the App Store or Google Play. If issues persist, try deleting and reinstalling the app to remove any corrupted files or settings that might be affecting print output1.

3. Confirm Bluetooth and Device Connection
- Check that your phone is properly connected to the printer via Bluetooth; unstable connections can cause incomplete or degraded print jobs. If not connected, remove the device from your Bluetooth list and reconnect as directed by Kodak support1.

4. Printer Driver and Software Troubleshooting
- For PC printing, ensure you have the latest Kodak printer drivers installed. Outdated drivers can cause image artifacts, color problems, or lines on prints. Visit the manufacturer’s website for the most recent updates3.

5. Check and Adjust Printer Settings
- In your print dialog, make sure the media type is set appropriately (e.g., “Other Photo Papers” rather than a different brand). Also verify you’ve selected the correct paper size, quality setting, and orientation. Printing from different applications may yield different results; if one app prints poorly, test with another (like the Kodak app or a photo editor)23.

6. Inspect Cartridges and Paper
- Cartridge problems, such as ink sticking due to long periods of inactivity, can affect print quality. If you suspect a cartridge issue, gently remove and reinsert it, or replace if necessary4.
- Make sure you are using the recommended photo paper and that it is loaded correctly.

7. Try Different Export Formats
- If your images are not printing correctly, exporting or saving your photos in a standard color profile (such as sRGB) can prevent compatibility issues5.

8. Contact Support if Needed
- If you have tried all troubleshooting steps and still experience poor print quality, consider reaching out to Kodak’s customer support for additional help. Their agents can guide you through more advanced diagnostics or warranty claims68.
