Customer's software creates a file that contains checks, check detail and EOBs. The checks are drawn on multiple banks. The client wants the checks on check stock and the EOBs on plain 24#. Zytron created a front end processor and check templates to accommodate this specification. Check stock is loaded into one of the printer trays and blank 24# into the other. Our front end software inserts printer commands that cause the selection of the required tray. When a check is called the proper template is pulled from printer memory. When check detail exceeds the space on the check plain paper is pulled to continue print. In order to maximize postage two files are created. One is for machine inserting and OMRs (inserter commands) are added. The other is for bundles which exceed inserter capabilities. These are placed into 9X12 envelopes.
