As shown in the block diagram, the Host Side is made up of:
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.
