A printing device includes a user interface, a print module and a locked print module. The locked print module is configured to examine a plurality of print data received by the printing device to determine whether locked printing is specified for any electronic documents contained in the plurality of print data. If locked printing is specified for any of the electronic documents contained in the plurality of print data, then the corresponding print data is stored on the printing device and not processed for printing. The locked print module is further configured to verify password data with respect to user identification data. If the password data is not successfully verified with respect to the user identification data, then the locked print module causes print data that is both stored on the printing device and associated with the user identification data to be deleted from the printing device.
