failed transmissions.
TIFF
Tagged Image File Format (TIFF) is a variable-resolution bitmapped
image format. TIFF describes image data that typically come from
scanners. TIFF images make use of tags, keywords defining the
characteristics of the image that is included in the file. This flexible
and platform-independent format can be used for pictures that have
been made by various image processing applications.
Toner Cartridge
A kind of bottle within a machine like printer which contains toner.
Toner is a powder used in laser printers and photocopiers, which
forms the text and images on the printed paper. Toner can be melted
by the heat of the fuser, causing it to bind to the fibers in the paper.

counterfeiting.
WIA
Windows Imaging Architecture (WIA) is an imaging architecture that
is originally introduced in Windows Me and Windows XP. A scan can
be initiated from within these operating systems by using a WIA-
compliant scanner.
