print speed
Measured in inches per second (ips), the rate at which media travels past the
printhead.
printhead
The mechanism inside the printer that prints. The printhead consists of 896
thermal elements (the 4406 contains 672 elements).
printhead elements
The parts of the printhead that print by placing a mark on the label when
heated. Each element is 0.00485 square inches in area (the printhead for the
4406 is 0.006575 square inches), and is switched on and off separately in order
to react with the media or thermal transfer ribbon to create a mark on the label.
printhead range
The range over which the resistance of the wires that carry energy to the
printhead elements can vary before sending a warning. The wires are tested
with each Printhead Test.
printhead test
A test that takes place each time the printer is turned on, or receives a specific
command from the host. This test makes sure the resistance of the wires that
carry energy to the printhead elements are within the acceptable range, which
ensures the temperature of the elements is within the acceptable temperature
range.
ready
The state in which the printer is able to print; the normal operating state of the
printer.
Ready/Busy line
Pin 11 of the rear panel connector. Indicates the printer is ready or not ready.
ribbon save
An optional device for some Intermec printers that disengages the thermal
transfer ribbon while labels are being fed forward, or any other time printing
does not take place. The 4400 printer does not offer this option.
RS-232
Standard for serial binary data interchange. The standard covers the physical,
electrical, and functional characteristics of the interface.
