Engine As shown in the block diagram, the Host Side is made up of: s3300-162 ■ Driver - a Windows software application that translates printed data to one of the printer languages, and creates a spooler file. ■ Web-based Application - offers various printer additional functions: management of printing jobs, printer administration, status monitor for monitoring printer status in real time on the Web, independent environment on OS. ■ Stand-alone Application - similar in functionality to Web-based applications. ■ Port Monitor - manages the network communication between spooler and Network Interface Card, or various additional applications and Network Interface Card, (this is, at first, make communication logical port, manage the data, transfer them from spooler to network port, and offer the result of printing). The Firmware Side is made up of: ■ Network Interface Card - relays communications between Host and kernel using various network protocols ■ Kernel - manages the flow control of emulation procedure, receiving data from Host or Network card and printing with engine & rendering job ■ Emulation - interprets the various output data from selected emulation ■ Engine - prints rendered bit-map data to paper with size and type required by Kernel. And then, for Job Spooling function for Multi-User, Multi-Printing that occurs in Network printing and various additional printing functions, this Kernel use max. 10 Queuing systems in a memory.
