摘要： According to approach for printing policy-enabled electronic documents, when a locked print module determines that an electronic document contained in the PDF print data is a policy-enabled electronic document, the locked print module causes the PDF print data to be stored on the printing device and not immediately processed for printing. A PDF-to-postscript conversion module generates and stores in a common data structure in the shared memory a request for security data for the PDF print data. A policy client module retrieves the request from the common data structure in the shared memory, obtains security data for the PDF print data from a policy server, and stores the security data in the common data structure in the shared memory. The PDF-to-postscript conversion module uses the security data to decrypt the PDF print data and then converts the decrypted PDF print data into postscript data for printing by the printing device.

摘要： 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.

摘要： An approach is provided for printing policy-enabled electronic documents using locked printing. A client device includes a user interface, an application program and a print driver. The application program allows a user to generate an electronic document. The print driver corresponds to a particular printing device and is configured to cause a graphical user interface to be displayed on the user interface. The graphical user interface allows a user to specify one or more access policies to be applied to the electronic document. The print driver is configured to generate print data that includes a plurality of print commands which, when processed by the particular printing device, cause a printed version of the electronic document to be generated at the printing device. The print data includes data that indicates the one or more attributes of the one or more access policies that are to be applied to the electronic document.

摘要： An approach is provided for implementing locked printing on a printing device. The printing device includes a user interface configured to display information and accept user input. The printing device includes a locked print process that is configured to examine print data received by the printing device and determine whether locked printing is to be used for the print data. The locked print process is further configured to verify password data entered via the user interface and if the password data is successfully verified, then allow the print data to be processed and a printed version of the electronic document reflected in the print data to be generated. The printing device also includes a Web server that provides a Web-based user interface to allow a user, such as an administrator, to specify configuration data that defines one or more functions performed by the locked print process.

According to the approach, a determination is made at a client device whether policy-enabled printing has been specified for a particular electronic document. If policy-enabled printing has been specified for the particular electronic document, then a determination is made whether a print driver, installed on the client device for supporting printing for a particular printing device, is configured to support policy-enabled printing. Also, a determination is made whether the particular printing device is currently configured to support policy-enabled printing. The particular electronic document is allowed to be processed at the client device for printing only if both the print driver is configured to support policy-enabled printing and the particular printing device is currently configured to support policy-enabled printing.

摘要： A printing device includes a locked print module that is configured to examine print data received by the printing device and determine whether the print data should be processed as locked print data. If so, then the print data is stored on the printing device and not immediately processed for printing. The locked print module also authenticates a user and allows the user to request printing of the print data. The user is queried for a password and if successfully verified, the locked print module determines a password type of the password associated with the print data and identifies password control data stored on the printing device that corresponds to the password type. The locked print module processes the print data based upon the password control data to generate processed print data and causes the processed print data to be printed at the printing device.

摘要： An approach is provided for printing policy-enabled electronic documents using locked printing. A printing device includes a user interface, a print process for processing print data and printing documents and a locked print process. When print data is received by a printing device, a determination is made whether an electronic document contained in the print data is a policy-enabled electronic document. If so, then the print data is treated as locked print data by being stored on the printing device and not immediately processed for printing. In response to both successfully verifying a user and a request to print the electronic document via a user interface at the printing device, a determination is made whether the user is authorized by a policy to print the electronic document. If so, then the print data is processed and the electronic document is printed at the printing device.
