An improved price updating apparatus for use in retail store pricing systems has an input for receiving update data indicative of a product for which a price change is desired and the changed price. The apparatus looks up records in a database (26, 29) relating to store locations, for locations where the product may be found. Where the location has an electronic price display device (24), preferably connected with the apparatus by a serial data link (23), the changed price is transmitted to the display device by the serial data link (23). Where the location has a printed price (48, 49), the apparatus stores a print job record containing information about the price and the shape and the size of the printed price. A user is later able to select, one by one, the various shapes and sizes of printed prices, and to print all the records intended for printing at the selected shape and size.
