Abstract: A user connected to a remote printer can choose to activate a print-monitoring feature of the printer as part of the submitted print job. As the job begins to print, the output of the printer is monitored for print quality. If an event occurs during the print job that affects the print job, the user receives real-time notification of the status of the print job. The events can be printer related such as paper jam or print job related such as poor print quality. The user can have an option of reviewing various parts of the print job during the printing process. There can also be an automatic print job out evaluation. If the user accepts the print quality, the printer will continue printing the job. If the user is not satisfied with the print quality, the job is halted and sent to a temporary print buffer. While the job is halted, adjustments are made to either the printer to improve print quality or to the print parameters of the print job to improve print quality.

Abstract: Disclosed is a system and method for optimizing submission of output jobs to a network of output devices, using an output job manager to assign jobs to devices. The assignments are done automatically, based on policies associated with users, output devices, organizations responsible for the output devices, and the system as a whole. User output preferences are expressed as one or more user policies. System and organizational constraints associated with users and output devices and the managing of groups of output devices are also expressed as policies. An optimizing scheduler calculates tradeoffs between user preferences, and factors in constraints to optimize submission of jobs to output devices, and to optimize use and wait times on the output devices.

Abstract: Forced compression halftone processes and forced compression techniques may be used to forcibly compress page raster images passed between a Digital Front End (DFE) processor and a Continuous Feed (CF) printer within a CF printing system. If a DFE processor determines that a compressed image size exceeds a static or dynamically predetermined threshold, the DFE processor may re-render the image using a “forced compression” halftone process, such as 2-to-1 forced compression, 4-to-1 forced compression, reduced resolution, etc. Once the page raster image has been re-rendered, the DFE processor may use a forced compression technique, which is complementary to the applied “forced compression” halftone process to re-compress the page raster image. The approach allows page raster images to be compressed to meet interface bandwidth constraints associated with the physical interface between the DFE processor and CF print engine, thereby allowing otherwise unprintable jobs to be printed with reasonable quality.
