The above Block Diagram is explained that:
Host Side is made up of
1) Driver that is Windows application software translate printed data to one of printer language and create spooler file.
2) Web-based Application that offer a various printer additional functions, management of printing job, printer
administration, Status monitor to monitoring the printer status by real time in Web, independent environment on OS.
3) Stand-alone Application that is a similar Window software as same as above 2.
4) Port Monitor that manages the network communication between spooler and Network Interface Card, or various
additional application 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).
Firmware Side is made up of
1) Network Interface Card is that relay the communication between Host and kernel using various network protocol.
2) Kernel is that manages the flow control of emulation procedure, receiving data from Host or Network card and printing
with engine & rendering job.
3) Emulation is that interprets the various output data from selected emulation.
4) Engine is that prints rendered bit-map data to paper with required size and type by Kernel.
And then, for Job Spooling function for Multi-User, Multi-Printing that is occurred in Network printing and various
additional printing functions, this Kernel use max. 10 Queuing systems in a memory.
