Glossary
Alphanumeric - A term used to identify characters consisting of letters, numbers, and other
symbols such as punctuation marks and mathematical symbols.
Bar code - Alphanumeric characters that are represented using a system of printed lines,
which can be read by a computer.
Blackline - A registration mark, typically a black line on the underside of certain media that
is used to identify the starting position of a label.
Blowhole -
A registration mark, typically a notched or cutout in certain media’s that is used
to identify the starting position of a label.
Continuous media - Media that contains no gap and continues as one piece of media.
CTS (Clear to Send) - A handshaking signal used to provide information when a DCE or
modem is ready to receive data in an RS-232 communication link. Used in conjunction with
RTS.
Cutter - An optional device, mounted on the printer, which is used to cut media into custom
sized labels after printing
DCE (Data-Circuit-terminating Equipment - The modem or printer end of an RS-232
serial communication link. Modem serial ports and other peripherals are typically configured
as DCE.
Die-cut media - Media that is cut using a die to form individual labels that have a start and
stop point. Typically the excess material surrounding the label is removed from the backing
material.
Direct thermal - Method of printing with a special heat-sensitive media that directly contacts
heat elements of a thermal print head. (See Thermal print head)
DPI (Dots Per Inch) - A unit of measure term used to identify the print resolution capability.
Drive roller - Platen roller that is located below the print head that is used to drive media
through the printer.
DSR (Data Set Ready) - A handshaking signal used to provide information about the status
of an RS-232 communication link. Used in conjunction with DTR.
DTE (Data Terminal Equipment) - The terminal or computer end of an RS-232 serial
communication link. Serial ports on computers are typically configured as DTE.
DTR (Data Terminal Ready) - A handshaking signal used to provide information about the
status of the communication line connected to the DCE end of an RS-232 link. Used in
conjunction with DSR.
