Label Liner (backing) The material labels are attached to during their
manufacturing process. Attachment is usually
accomplished with an adhesive. After printing, labels
can
be easily removed from the liner and the liner
discarded
or recycled.
Label Taken Sensor A sensor located at the front of the printer to detect the
presence of a label extended out the front of the
printer.
The sensor is used only during Peel-Off Media Handling
to sense a label and then
detect its removal prior to
printing the next label.
Media Material onto which data is printed by the printer. The
types of media supported by the printer are die-cut
labels or tag stock, supplied in roll or fanfold format.
Media is further described by the type of sensing
used
to detect the Top-of-Form position based on the
label
length indicators used. Transmissive (Gap)
media uses
a liner gap, notch, or hole between
labels, and
Reflective (Mark) media uses a horizontal
black mark
located on the underside of the tag stock
or label liner.
Continuous media (with no label length
indicators) uses
no sensing method, and the
operator determines which
label length is desired.
Media Sensor The sensor used to detect the presence of media in the
paper path as well as the gap, notch, or hole
position of
Transmissive media or the horizontal
black mark on
Reflective media.
Memory See RAM, Nonvolatile Memory, DRAM, and Flash
Memory.
Nonvolatile Memory Nonvolatile memory stores variables that must be
preserved when the printer is turned off, such as
configuration parameters and printer usage statistics.
NVRAM Acronym of Nonvolatile Random-Access Memory. See
Nonvolatile Memory.
Parity (check) Parity checking is the addition of a non-data bit to data,
resulting in the number of “1 bits” being either
always
even or always odd. Parity is used to detect
transmission
errors. Parity represents value in the
check digit of the
received or transmitted data.
PCBA Printed Circuit Board Assembly. A PCB with
components (ICs, resistors, capacitors, etc.)
installed.
