摘要

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.
