A printing system includes a printer and computers connected by an network. A mail server is provided for transmitting notification data from the printer to the computers in the form of an email message. Print data stored in the printer is erased once the print data has been used for reprint operations a certain amount of times. If the amount of print data stored in the printer exceeds a reference size, then print data sets are selected for erasure based on predetermined conditions. Data stored in the printer can be retrieved from the printer and amended at the computer.

An image scanner produces white level data when the white plate is irradiated with light. The image scanner produces black level data when the white plate is irradiated with no light. Correction data constructed from the thus produced white level data and black level data is transferred to the host computer. Next, the image scanner produces tone data for the original, and transfers the tone data to the host computer. In the host computer, the tone data is corrected into either one of the 256 levels '00' to 'FF.' This correction operation is attained with using average values of the transferred white level data and average values of the transferred black level data.
