Abstract
In a copying machine connected to the network, calibrations on the printers are performed as follows. When an execution of calibration is requested, the copying machine displays all identification numbers of the printers connected to the network on the operation panel of the copying machine. When the user selects a printer to be calibrated through the display, the copying machine causes the selected printer to output a specified test pattern. Then the copying machine reads the test pattern, generates a correction table and registers the generated table with the printer.
