OPC
Organic Photo Conductor (OPC) is a mechanism that makes a virtual
image for print using a laser beam emitted from a laser printer, and it is
usually green or gray colored and a cylinder shaped.

functional layers. The layers are, from top to bottom, Application,
Presentation, Session, Transport, Network, Data Link and Physical.
PABX
A private automatic branch exchange (PABX) is an automatic telephone
switching system within a private enterprise.
PCL
Printer Command Language (PCL) is a Page Description Language
(PDL) developed by HP as a printer protocol and has become an

how fast a printer works, meaning the number of pages a printer can
produce in one minute.
PRN file
An interface for a device driver, this allows software to interact with the
device driver using standard input/output system calls, which simplifies
many tasks.
Protocol

RADIUS

higher the dpi, the greater the resolution.
SMB
Server Message Block (SMB) is a network protocol mainly applied to
share files, printers, serial ports, and miscellaneous communications
between nodes on a network. It also provides an authenticated
Inter-process communication mechanism.
