Best Practices & Common Mistakes

Best Practices

Use High-Quality Labels: Invest in high-quality 2x1 labels designed for thermal transfer printing. These labels adhere better and provide better print quality.
Regular Cleaning: Clean the printhead regularly with a cleaning pen or swab to remove dust and residue. This maintains print quality and extends the life of the printhead.
