Systems and methods of identifying and processing complex text are provided. If a presentation data stream contains a complex text string, a preselected control in the presentation data stream is inserted before the complex text string. A first parameter has a value indicating a control type for controlling processing of complex text, and a second parameter takes one or more values for enabling and disabling the processing of complex text. In processing complex text, responsive to a first predetermined type of control in a presentation data stream, if the first type of complex text processing is enabled, this processing is applied to a complex text string succeeding the first predetermined type of control in the presentation data stream. The first predetermined type of control includes a first parameter represented by a corresponding value for controlling the first type of complex text processing.

Methods and systems for rendering code points on a presentation device with layout processing performed outside the presentation device. In one aspect, a layout processor translates one or more code points into a sequence of one or more glyph indices and corresponding positioning information. The glyph indices and corresponding positioning information may be included within a PTOCA control sequence. The glyph indices may be used by the presentation device to directly locate a corresponding glyph image in a font. The positioning information defines positioning of each glyph image so identified. Features and aspects hereof allow efficient layout of complex text in which glyph images and positioning may be dynamically determined in accordance with context or other attributes. The processing burden of such layout processing is removed from the presentation device without significantly increasing data transmission bandwidth between the presentation engine and external system utilizing the layout processor.

A method, computer program product and system for switching fonts without embedding font switching commands in the data stream (logical description of the print document) between a client and a print server. The client in a printing system may receive a character where the character is a modified character in a base font resource or is a character to be added to or deleted from the base font resource. The client may create a font resource that includes the received character. The client may further link the created font resource with the base font resource or vice-versa thereby allowing a user to use both the characters in the base font resource and in the linked font resource as if they were a single font resource without building or buying a special purpose font resource. Consequently, font switching commands are no longer necessary to be embedded in the data stream.

The print system MO:DCA Architecture is extended to handle non-native print objects for controlling and operating RFID writer or reader devices without requiring separate control data streams or systems to be implemented at the host computer. References and command identifiers are placed in the page description data from the host computer so that RFID information can be retrieved and downloaded to the printer and RFID apparatus when the print data is being processed in the print server or main processor of the printer without interfering with normal operation of the printer itself.

A method of communicating non-native print objects in MO:DCA Architecture for controlling and operating RFID writer or reader devices without requiring separate control data streams or systems to be implemented at the host computer. Data references and command identifiers are placed by application program means at the host computer into the page description data so that RFID information can be retrieved and downloaded to the printer and RFID apparatus when the print data is being processed in the print server or main processor of the printer without interfering with normal operation of the printer itself.

Systems and methods for implementing a fast, color printer architecture are disclosed. A print processor comprises a plurality of processing units operating in parallel to process data for different layers or color planes. A connection can be formed between any processing unit and any print head of one or more printers. Any one of a plurality of the parallel processing units may be assigned to process one, some, or all of the colors of data. Consequently, each one of a plurality of print heads can be assigned to receive data from any one of a plurality of processing units.

Provided is a method, system, and program for interfacing with a printer driver. Data and an acknowledgment request is received from the printer driver. The printer driver does not send further data to print until receiving an acknowledgment reply indicating that the transmitted data passed an initial check to improve printer performance. An acknowledgment reply is transmitted to the printer driver in response to the acknowledgment request before completing the initial check of the sent data to cause the printer driver to send further data. Data processing operations are resynchronized in response to detecting an error in the received data. The received data is rasterized and outputted.

A method is disclosed. The method includes identifying a received object to be cached, calculating a time to rasterize the object, determining if the rasterize time is greater than a time to reuse a rasterized image of the object, caching the object if the reuse time is greater than the rasterize time and caching the rasterized image of the object if the rasterize time is greater than the reuse time.

Apparatus to collect solar radiation using a series of lenses or mirrors that concentrate the solar energy onto targets. A gaseous working fluid flowing through the targets is heated and optionally supplied to a heat store having an internal walled labyrinth of a suitable material to store heat energy. A heat exchanger, turbine and electricity generator are coupled to the collection and storage apparatus so as to provide a power plant for the conversion of solar energy to electricity.
