processing.
Develop print-job management, buƯ er management and high-speed image/data handling.
Develop line-driver software coordinating thermal printhead strobing, paper-feed motor and print
timing.
Develop firmware for normal, high-speed, bold, image and cutter operating modes.
Develop and maintain firmware architecture, drivers and hardware interfaces.
Model-Based Development & Control
