Hi! I understand you're experiencing poor print quality with your Nelko printer app. Let's work through this together to get your prints looking crisp again.

To start, can you tell me a bit more about what you're seeing? For example:
- Are the printouts faint, blurry, or missing sections?
- Is this issue happening with every print, or just sometimes?
- Have you noticed if it worsens after a period of printing, or right from the start?
- What kind of labels or paper are you using—are they original Nelko supplies?

Meanwhile, here are some common, easy steps we can try first to improve print quality:

1. Use genuine Nelko label paper — Using original supplies ensures compatibility and the best print results. Removing any green sticker on the label roll core can cause misidentification by the printer, so keep that intact.

2. Clean the print head — Thermal print heads can accumulate residue leading to fading or streaking. Carefully wipe it with a lint-free cloth and some isopropyl alcohol as per the manual.

3. Check printer settings in the Nelko app — Sometimes adjusting print density or resolution improves quality. Open the app, select your printer, and look for options to increase print darkness or quality.

4. Ensure the label size matches the app and printer settings — Mismatch can cause cut-off or poor quality. Set size to 4x6 or as per your label roll.

If you've already tried these or if the problem persists, let me know. We can then take a deeper look into app configuration and printer firmware if needed.

Does this help for now? Or would you like me to guide you through any specific steps?
