RS-422
Standard for the voltage and impedance levels for serial data transmission on
balanced lines. Similar to RS-232, but handles larger distances and faster
communication.
RS-485
Standard for allowing multiple devices to share a common set of serial data
communication lines. The signaling is very similar to RS-422. The maximum
number of devices allowed is 32.
scan
To read a bar code with a device known as a scanner that converts optical
information into electrical signals.
selective transfer
A procedure that copies selected formats, fonts, graphics, or pages stored in the
memory of one printer to the memory of another.
self-strip
An internal device for the printer that presents each label after it is printed,
with the backing removed so it may be applied immediately. Self-strip is a
standard feature on the 3400, 3440, and 3600 printers.
sensitivity
The responsiveness of thermal media, or of thermal transfer ribbon, to heat; it is
determined by the time required for a unit measure of heat to affect the media
or ribbon.
serial
A communication scheme in which the bits of a byte are transferred one at a
time. Often serial transmission is used to link host computers to terminals and
PCs to printers.
soft font
A file stored in the printer to provide the ability to print text using fonts that
are not resident in the printer.
Standard protocol
A communications protocol capable of controlling communications between
two devices connected by a single data communication line.
