A raster image processor (RIP) system is used in a printing system to process a variety of different jobs. A front end receives the jobs and determines the job type. The job types include a print job, a preview job, and an estimation job. Depending on the type of job, the front end configures the RIPs within RIP system accordingly to process the job. The RIPs may process the job in parallel, with a high performance RIP processing the first page of the job. If the job is not processed in parallel, then the front end assigns the job to a very high performance RIP. The front end also assigns the preview job to a preview RIP and the estimation job to an estimation RIP. The front end configures RIPs as needed.

A method of logging thread parallelism data include executing a plurality of threads at a multicore processor associated with an operating system to perform symmetrical multiprocessing. The method also includes tracking, at a logging subsystem of the operating system, an accumulated runtime associated with each thread combination of the plurality of threads during execution of the plurality of threads. The accumulated runtime of a particular thread combination increases while the particular thread combination is running on the multicore processor in parallel. The method also include generating, at the logging subsystem, logging data indicating the accumulated runtime for each thread combination. The method further includes outputting the logging data. The logging data is usable to increase thread parallelism at the multicore processor.

A printing system includes a digital front end (DFE) system connected to a plurality of printing devices. The DFE system manages printing operations to the plurality of printing devices. The DFE system also includes a printing device connectivity manager to manage connections with the printing devices. Printing connectivity modules are installed at the printing device connectivity manager using application programming interfaces (APIs) that are loaded at the creation of the printing connectivity modules. The DFE system also includes a display device connectivity manager to manage connections with display devices using display connectivity modules and display connectivity APIs. The DFE system also includes a storage connectivity manager to manage data storage and storage devices using storage connectivity modules and storage connectivity APIs.

The DFE system also includes a printing device connectivity manager to manage connections with the printing devices. Printing connectivity modules are installed at the printing device connectivity manager using application programming interfaces (APIs) that are loaded at the creation of the printing connectivity modules. The APIs allow the printing connectivity modules to interact with the printing devices. The printing connectivity modules can communicate with application modules located at the printing devices.

An example embodiment may involve causing a page of a document to be printed on a printing device, wherein the printing device is in an AM halftoning mode and prints the page using an AM halftone; displaying, on the display unit, a graphical user interface, wherein the graphical user interface includes a selectable option to switch the printing device from the AM halftoning mode to an FM halftoning mode; receiving an indication that the selectable option has been selected; possibly in response to receiving the indication that the selectable option has been selected, causing the printing device to switch from the AM halftoning mode to the FM halftoning mode; and causing the page of the document to be printed again on the printing device, wherein the printing device is in the FM halftoning mode and prints the page using an FM halftone.

Example systems and related methods may relate to monitoring performance of an image forming operation. Namely, a system includes an image forming apparatus configured to execute an operation in response to receiving instructions to execute the operation. The system further includes an external sensor circuit that includes one or more sensors and a processor. The one or more sensors are configured to detect a status of an operational parameter of the image forming apparatus indicative of the image forming apparatus executing the operation and receive an instruction to exclude at least a portion of data used to detect the status of the operational parameter. The system further includes a host computing device. The host computing device is configured to generate a plurality of timestamps indicative of when the image forming apparatus executed the operation and a time frame when the external sensor circuit excluded data.

The system yet further includes a host computing device configured to generate, in response to receiving notifications of a status of the operational parameter received from the one or more processors of the sensor circuit, a first timestamp indicative of when the image forming apparatus started to execute the printing operation, and a second timestamp indicative of when the image forming apparatus completed the printing operation. The host computing device is further configured to generate a log file. Data of the log file includes the first timestamp and the second timestamp, and is indicative of how quickly the image forming apparatus executed the operation.

Example systems and related methods may relate to compressing a plurality of data channels. An example embodiment may include a controller determining a plurality of interleave allocations within a memory allocation. The interleave allocations correspond to a plurality of planes, which may represent color information planes. The plurality of data channels may be compressed into a plurality of compressed data channels. Subsequently, each of the plurality of compressed data channels may be stored at respective interleave allocations. A full interleave allocation condition may be determined based on a capacity of a respective interleave allocation being less than a predetermined threshold. In response to determining the full interleave allocation condition, a new interleave allocation may be requested from the controller. In response, the controller may determine a new interleave allocation.
