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 positioned under it. The
sensor is used only during Peel-Off and Tear-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 tagstock, supplied in roll or fanfold format.
Media is further described by the type of sensing
used to detect the Top of Form position of its
predetermined length. Transmissive media uses a
liner gap, notch or hole between labels and
Reflective media uses a horizontal black mark
located on the back of the tagstock or label liner.
Continuous media uses no sensing method and the
operator determines which label length is desired.
Media Cutter An optional device attached to the front of the printer
that cuts the media after it is printed into individual
labels or after a specified number of labels.
Media Sensor The assembly 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.
Nonvolatile memory is preserved because RAM is
housed on the controller board, which contains an
independent, battery-operated power supply. When
printer power is turned off, the battery supplies the
power needed to keep stored data active. Nonvolatile
memory also includes storage in disk.
NOVRAM 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.
