Background Forms
Xerox FreeFlow® Print Server IPDS supports both creating background forms from IPDS jobs and
merging IPDS jobs with background forms created either from IPDS or other PDLs.
For more information, refer to Using Background Forms in the Xerox FreeFlow® Print Server online help.
Barcode Symbology
Xerox FreeFlow® Print Server supports printing of many IPDS Bar Code Object Content Architecture
(BCOCA) barcode symbologies. Xerox FreeFlow® Print Server accepts and validates all BCOCA data
structured field values prior to printing the barcode. When there is an error in the barcode data, an
appropriate exception is reported to the host. All barcodes printed meet the symbology specification
standard for the selected barcode.
Applications can take advantage of the Xerox FreeFlow® Print Server ability to generate barcodes
based on the data supplied or they can generate barcodes using fonts or graphics as may have been
done in the past.
Xerox FreeFlow® Print Server also supports the new United States Post Office Intelligent Mail Barcode
or '4-State Customer Barcode' (4-CB), as part of the IPDS Gateway.The Intelligent Mail Barcode was
formerly called OneCode
Solution
Barcode.
The 4-CB uses the same barcode commands as all other supported IPDS barcodes. Please see the IBM
Bar Code Object Content Architecture Reference, S544-3766-06 for specific commands.The 4-CB has 4
modifiers that determine how many numbers the barcode uses:
• Modifier X'00' is a tracking code only and is 20 digits long.
The remaining modifiers all include various amounts of routing information.
• Modifier X'01' includes a 5 digit routing code.
• Modifier X'02' includes a 9 digit routing code.
• Modifier X'03' includes an 11 digit routing code.
If the modifiers do not contain the correct number of digits, or the modifiers are not all numeric, an
error will be posted. Additionally, the second digit of the barcode is checked for a number between 0
and 4. If this post office requirement is not met, an error will be posted. The barcode generated is
always 65 bars long no matter how many input digits are provided.
The 4-CB is available in two sizes: Optimal, which is approximately 2.9" long, and small, which is
approximately 2.575" long. The default size is optimal which is specified by entering the default value,
X'FF', in the module width field of the Bar Code Symbol Descriptor record. Any value in the module
width field between X'00'and X'FE' will result in a small size barcode.
The human readable interpretation (HRI) line can be located either above or below the barcode,
however, the post office prefers above. When an HRI line is requested it should be understood that
when the small barcode is in use the HRI line for modifiers X'02' and X'03' will be longer than the
barcode itself. This is because the post office requires it to be in a 10 point font.
