  3. I. Laser Beam Printer • Hardware & ASIC Control • Emulation : SPL, PCL, EPSON/IBM • Emulation Interface • Engine Control • Panel Control (LED, Key) • Host Interface : USB 2.0(or 1.0), Network Printer Driver Print Command 1. Convert the Image to PDL 2. Transfer the PDL F/W After processing the PDL, print the image

  4. II. Architecture of F/W Application Layer • Application Layer • (Emulation) • Kernel Layer • (pSOS+ & Kernel) Kernel pSOS+ • Hardware Access Layer • (Hardware Control) F/W Driver Module Board Support Package Hardware • Physical Layer • (Hardware)

  5. III. F/W Initialization • Turn on printer : Jump to reset vector, Start booting Booting • Initialize BSP • start kernel Kernel • Initialize the system of F/W • (Cache/Timer/Environment/Memory/Interface) • Initialize the parts dependent of model • Initialize the engine interface • Search a emulation
