Abstract

A printer includes an obtaining section for obtaining printing data, a storage section for storing the printing data obtained by the obtaining section, a printing section for printing the printing data stored in the storage section, an receiving section for receiving information about the printer, and a control section for extracting predetermined information about the printing data from the printing data and protecting the confidentiality of the printing data on the basis of the extracted information and the information received by the receiving section.

Description

Technical field [0001] The present application relates to a printer for receiving and storing print data to be printed, and printing the print data on a recording medium based on the stored print data, and more specifically, to a printer capable of storing confidentially The printer that prints the data. Background technique [0002] By connecting a printer to two or more computers via a network such as a LAN (Local Area Network) to constitute a printing system, it is possible to share the printer as a common hardware resource among users of the computers. Generally, when printing is completed and discharged from the printer to the outside, the printing medium (for example, recording paper) in such a general printer can be obtained by anyone, and therefore, it is difficult to maintain the confidentiality of the printed data. [0003] Specifically, when a user who is a company or office employee operates the printer by himself, confidential data may be leaked through any employee'...
