Printed receipts often show faint text or fine lines that are difficult to read. These issues can affect customer satisfaction and the professional image of a business. Traditional firmware‑based density adjustments reached their limits. Earlier Bold Line options expanded pixels too aggressively, which led to blurred edges and reduced readability.
BIXOLON’s upgraded Windows POS Driver applies a refined pixel‑addition method. Instead of expanding pixels uniformly, they are added one at a time in specific directions—left, top, right, and bottom. This controlled process enhances visibility while preserving clarity, especially for fine details.
Pre-Upgrade: Uniform Pixel Expansion
