A system and method for bulk mail oriented transaction printing of variable documents by evaluating particular data such as zip code data in a VI PDL. A queue can be configured with information regarding a particular rendering job, which includes the VI data fields including required postal information, a particular postal information format, and a thickness adjustment with respect to each item of mail associated with a bulk mail. The rendering job can be received for production and a number of records associated with the job automatically parsed into one or more postal bundles, based on predefined information and postal regulations. Such an approach can also be utilized to automatically generate and render the required bundle labels.
