Abstract
A printing system according to the present invention includes a media terminal box which may be installed on a street. In the box, there are disposed a measuring device that measures the temperature or humidity in the box, a device such as a CPU, and a storage device. The storage device stores correction data including a correction value based on a combination of the temperature and humidity, and history data relating to the temperature and humidity measured by the measuring device. The control device corrects a color tone of image data which is read out from the storage device based on the temperature/humidity history data and the correction data so as to generate corrected image data. The corrected image data is sent to a printer, and then the printer is operated based on the corrected image data.
