Method and system for automatic generation of indicia labels in a mail processing system

A mailing machine having a continuous feed function that automatically generates an indicia label based on physical attributes of a mail piece is disclosed. The weight of a mail piece is determined utilizing, for example, either differential weighing or single mail piece weighing. If the determined weight does not exceed a predetermined threshold limit, the mail piece can be fed into a processing path of the mail processing system and an indicium evidencing payment of postage can be printed directly on the mail piece. If the determined weight of the mail piece, or the determined thickness or width of the mail piece, exceeds a predetermined threshold limit, the mailing machine will automatically print the indicium for the mail piece on a tape.
