Data Editing
Data Editing Overview
When a bar code is scanned, additional information can be sent to the host
computer along with the bar code data. This combination of bar code data and
supplementary user-defined data is called a “message string.” The features in
this chapter can be used to build specific user-defined data into a message
string.
There are several types of selectable data characters that can be sent before
and after scanned data. You can specify if they should be sent with all symbol-
ogies, or only with specific symbologies. Figure 3 shows the available elements
you can add to a message string:

Please Keep In Mind...
• Modifying a message string is not a mandatory requirement. Data editing
is sophisticated feature allowing highly customizable output for advanced
users. Factory default settings for data editing is typically set to NONE.
• A prefix or suffix may be applied (reference the Symbologies on page 65
chapter for these settings) across all symbologies (set via the Global fea-
tures in this chapter).
• You can add any character from the ASCII Chart on page 295 (from 00-FF) on
the inside back cover of this manual as a prefix, suffix or Label ID.
Enter prefixes and suffixes in the order in which you want them to appear on
the output.
NOTE
Additional advanced editing is available. See the Advanced Formatting
features in the HP USB Scanner Configuration and Firmware Utility.

Label ID Transmission:
Enable this option to
transmit the Label ID you
configure for the scanned

AIM ID: This function is used to identify and display the
common label identifier for its symbology. When enabled,
this ID code will be transmitted before the scanned bar
code data.
