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.
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 and
Tear-Off Media Handling to sense a label and then
detect its removal prior to printing the next label.
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.
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.
See RAM, Nonvolatile Memory, DRAM, and Flash
Memory.
Nonvolatile memory stores variables that must be
preserved when the printer is turned off, such as
configuration parameters and printer usage statistics.
Acronym of Nonvolatile Random-Access Memory.
See Nonvolatile Memory.
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.
Printed Circuit Board Assembly. A PCB with
components (ICs, resistors, capacitors, etc.)
installed.
