A print head maintenance manifold assembly is disclosed. The maintenance manifold assembly includes a multitude of hoses and a manifold coupled to the hoses via fittings. The manifold includes a first set of fittings and small diameter hoses coupled to print heads at a first section of the manifold and a second set of fittings and hoses coupled to a vacuum source at a second section of the manifold.

A method is disclosed. The method includes generating a seed pattern which ensures one dot per column, computing an auto correlation function and performing pixel error processing. Pixel error processing includes performing multiple operations during each iteration to create visually pleasing halftone mask patterns which follow a one dot per column constraint.

A method disclosed. The method includes receiving a Portable Document Format (PDF) print job file, applying a first transform to generate an Advanced Function Presentation (AFP) image print job data stream and applying a second transform to generate an AFP text print job data stream.
摘要:
A system is disclosed. The system includes a print engine having one or more ink jet print heads and ink lines coupled to provide ink to each of the print heads. The system also includes a fluid change manifold coupled to the ink lines to remove fluid from the print engine via the ink lines.

A printing system is disclosed. The printing system includes a first printer to print a first type of data to a medium and to print a first barcode on the medium including variable to be printed on the medium and a second printer to print the variable data to the medium based on the first barcode and to print a second barcode to the medium for verification that the variable data has been accurately printed to the medium.

Provided are a method, system, and article of manufacture for using a resource context to access resources and source data for a transform. A transform receives a request to transform source data and calls a resource context. The resource context initializes a resource object for the transform and acquires associations to source data and resources needed by the transform. The resource context maintains the acquired associations to source data and resources in the resource object for the transform and supplies the associations to the source data and resources to the transform. The transform transforms the source data using the resources to produce output and provides the output to the resource context.
摘要:
An ink jet printing system includes a first print system having a first ink system to print received print jobs, a second print system having a second ink system independent of the first ink system to print the print jobs and a control unit to receive the print jobs and determine which of the first and second print systems is to print each received print job.

A printer, fax machine, copier, scanner, or any other office device used by multiple users from multiple locations is provided with improved apparatus and/or software for locking out all incoming commands from reaching the device's internal controller except for commands coming from a newly-designated primary controller used by the service technician. This lockout can be used with any type of office machine that has it's own internal controller, so it applies equally to all types of office machines and systems generally used in today's office environments.

A halftone method and apparatus provides a line screen frequency of N/2 for a printer resolution of N without negative print effects. A 300 lines per inch halftone screen for a 600 dpi printer may thus be created by alternating white and saturated colored lines when half of a given color component's pels are on. Empirical rules are used to create the screens based on how that printer creates consistent and reliable levels for each color component. These rules allow intermediate intensity values between white and full-on at each pel. Since the halftoning is done in the hardware just before printing, the print direction relative to the threshold matrix is known. No rotation capability is needed in the hardware. If an image needs to be rotated, it can be done previously to being sent to the hardware. Furthermore, because a pair of pels are turned on for the lightest values (or possibly with a one level difference between the first and second dots in the pair), the electronics are stressed less. Moreover, the drive will be at a lower frequency than the first dot in the traditional halftone cell, which remains isolated for many levels.
摘要:
Methods, systems, and apparatus for generating and associating meta-data with a final form presentation datastream document where the meta-data is structured in accordance with the datastream component architectures. Meta-data objects (“MDOs”) are architected as components of a presentation document and thus are well defined to allow applications to reliably access and process the meta-data contained therein. The MDOs may be associated with other components of the document and are architected to be extensible and flexible while still adhering to an architectural structure. The MDOs may be descriptive (no affect in document presentation) or operational (affects document presentation if processed). Standard types of MDOs may include XML standard information, JDF standard information, PWG standard information, and digital signature information. A variety of standard categories further define typical meta-data forms and applications thereof.
