Abstract: A system for preparing shipping documents includes a processor, a keyboard, a display, a memory and a printer. Associated with the printer are a single sheet feeder, a batch feeder and an endless form feeder. The system is capable of preparing a wide variety of waybills and other shipping forms. The system is also able to prepare automatically all shipping documents required for a mass shipment to a user-defined group of recipients. A user activated "help" function provides information specific to the type of data that the user is attempting to enter at the time the help function is activated. There is also a "rare shopping" function that allows the user to define for each shipping mode a group of other shipping modes for rate comparison purposes.
