Postamble
Sets the postamble that is appended to any data you scan.
Common postambles include cursor controls such as a tab or a
carriage return line feed. You can set Postamble to up to 20
ASCII characters.
Postnet
Enables or disables decoding of Postnet symbology. The Postnet
(Postal Numeric Encoding Technique) bar code was invented by
the U.S. Postal Office to encode ZIP information. Having your
letter printing system Postnet-capable enables you to receive a
discount on the postage. The U.S. delivery address coding can be
of three forms (1) 5-digit ZIP; (2) 5-digit ZIP + 4 code (3) 11-
digit delivery point code. So a valid Postnet bar code contains
either 32 bars, 52 bars or 62 bars. Postnet is a numeric
symbology. Different from most other symbologies, Postnet has
requirements to the actual bar height and width. The
information is encoded in the height and has nothing to do with
the spaces.
Preamble
Sets the preamble that precedes any data you scan. Common
preambles include a data location number or an operator
number. You can set Preamble to up to 20 ASCII characters.
Predefined Security Levels
Defines the security level to use when decoding bar codes. When
you select a lower decode security level, the SR61 can decode bar
codes with poorer print quality.
QR Code
Enables or disables decoding of QR Code symbology. QR Code
is a 2D matrix symbology containing dark and light square data
modules.
RSS 14
Enables or disables decoding of RSS 14 (Reduced Space
Symbology 14) 1D or stacked 2D codes. RSS 14 is a numeric
symbology that can read stacked omni-directional bar code
labels. It is a member of the EAN.UCC RSS symbology family.
