The demand for "high quality" in this context refers to the driver’s ability to produce crisp, legible receipts. In a retail setting, a faded or garbled receipt can lead to customer disputes and returns. The APD manages the rasterization of text and graphics, ensuring that barcodes scan correctly and that fonts remain sharp. By offloading some of the processing work to the driver software, the TM-T81 can print at its advertised high speeds, preventing bottlenecks at the checkout counter during peak hours.
