Thermal Head Print Control for Barcode Quality and Speed

The patent applies different print densities to different regions of the print medium. Specifically, a first print density is used for a first region containing barcodes or logos that require high quality, while a second (lower) print density is used for a second region with general text and information. This allows the system to improve print quality where needed without sacrificing overall print speed.

The patent implements region-specific print quality control by identifying a first region requiring high print quality (containing barcodes or logos) and a second region with standard requirements. The system prints the first region at a first print speed and the second region at a second print speed, where the first print speed is lower than the second print speed. This selective approach improves print quality for critical elements while maintaining high productivity for the overall printing process.

The patent reduces thermal head wear by applying high print density only to specific regions requiring high quality (first region with barcodes or logos) while using lower print density for other regions (second region with general information). This selective high-density printing maintains print quality where necessary while significantly reducing the cumulative wear on the thermal head, thereby extending its operational lifespan.
