In Adagio AP, the vendor zip code is being sent to Print Boss as part of the address line instead of in the zip code field. I have checked with Stu at Wellsprings and he confirmed the data in the Raw Capture feature of Print Boss. Is this a known issue or feature? Please let me know if you need further information.
The information that is sent to Print Boss is controlled by the specification you (or your Adagio consultant) have designed. You'll need to look there to determine the problem and solution.
