A scanner is connected to a printer to form a simple copying system in which the printer is controlled from the scanner. In one aspect of the invention, the scanner queries the printer to learn features implemented in the printer, and constructs a menu enabling a user of the scanner to control use of the printer's features, so that the scanner can be connected to a variety of printers without the need for firmware modifications. In another aspect of the invention, the printer has an accounting feature and manages printing fees according to account identifiers input by the scanner, eliminating the need to use copy cards to collect copying fees. |
