ABSTRACT:
A barcode identification system is shown that includes a user operable personal computer for creating print jobs. The personal computer is coupled to a number of printers for printing the data for a job in a selected format on a record member such as a tag, label or the like. The system employs modular software. During the initialization of each of the software modules, the system determines whether the module includes a key identification that matches a system key and if not, the operation of the software module is limited to a demonstration mode if that mode is allowable. A data entry routine aids the user entering valid data for a selected format. In response to a print command, the data entered by the user is combined with the selected format to form a job. The job is then sent to a spooler which distributes the job to one of the barcode printers of the system.
