1.The print data is output from PC:
through Wired-LAN and pass the PHY(IC750) and LAN I/F in IC300.
through Wireless-LAN and pass the WLAN module(IC850) and USB I/F2 in IC300.
through USB and pass the USB I/F1 in IC300.
through Wireless-LAN and pass the WLAN module(IC850) and USB I/F2 in IC300.
through USB and pass the USB I/F1 in IC300.
then the data is stored in IC400/401 through SDRAM I/F.
2. If necessary, the data is decompressed via JBIG.
3. Print I/F retrieve the data from IC400/401 and output it to LSU.
