Abstract: A printing system wherein pre-printing commands, print data, and post-printing commands are nested in a data stream, the commands bounding a group of print data pages in the data stream, the group of pages containing one or more page data blocks, and the commands defining one or more operations to be performed relative to the group of pages. Groups of pages are handled in accordance with the commands in the data stream, and the commands are buffered while a print processor processes the group of pages to form printed sheets therefrom.

Abstract: This invention is a method for annotating and redacting a final-form document archived in a computerized system where it is important that the fidelity of the final form document is preserved. More particularly, this method allows final-form documents containing objects such as texts, graphics and images to be annotated or redacted by other objects carried in the same data stream without compromising the integrity of the original document.

Abstract: Instrumentation logic is provided to map object oriented protocols to efficient data management protocols to provide direct, keyed access to multiple data entries. An object oriented database is utilized to model a complex process since it is easily extended to include tables of transactions for each of the many process steps in a complex operation. The database is accessed through the Desktop Management Interface (DMI) with individual DMI commands issued to get or set each individual entry. An application requiring access to many entries would require detailed knowledge of the database and would need to generate many DMI commands. For such an application, instrumentation logic is provided and is accessed by the application through a normal DMI command. The instrumentation then generates all of the successive DMI commands needed to access multiple entries.

Abstract: This invention is a process for interconnecting an all points addressable printer with a host application program wherein the application presents output to be printed to the printer and wherein the host application can be present on a variety of different computer equipment such as a large host computer, a standalone workstation, or workstation on a local area network and wherein the all points addressable page printer can utilize any type of printing technology such as electrophotographic, magnetic or other and wherein the printer and the application host are interconnected by communicating means such as a channel, local area network, or telecommunication line and wherein any type of transmission protocol can be used and wherein the process enables the transmission of commands and data from the host application to the printer in a manner which is independent of the communication means and transmission protocol.
