Abstract: An in-line array of product dispensers (16a; 16b; 16c; 16d) overlie a conveyor belt (10). An ink jet printer (32) overlies the conveyor belt downstream of the product dispensers. Information identifying the product dispensers which hold the desired products for a particular set and the desired number of sets of that type are entered to a controller (34) operatively associated with the product dispensers and the printer. The controller times the dispensing of products from the selected product dispensers so as to form imbricated sets of products on the counveyor belt. As the products in the imbricated set pass under the printer, the controller activates it to print desired information on the exposed portion of each product.
