US Patent:

7085014, Aug 1, 2006

Filed:

Jun 6, 2001

Appl. No.:

09/876507

Inventors:

John B. Condon - Berthoud CO, US
Joan LaVerne Mitchell - Longmont CO, US
David Joseph Shields - Louisville CO, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04N 1/405

US Classification:

358 306, 358 313, 358 314

Abstract:

A method, apparatus and article of manufacture for providing improved print quality regardless of media smoothness is disclosed. Information regarding the smoothness of media is ascertained and the information about the media smoothness is used in the generation of an output. A selectable halftone screen is used in the print device to provide different halftone screens for different media smoothness. The halftoning screens can be changed depending on the roughness of the media being used. Pre-defined halftone screens may be stored and selected for a range of media smoothness. The selection of the pre-defined halftones may be selected by the operator or may be selected automatically by the print device.

US Classification:

358 306, 358 313, 358 314, 347101

Abstract:

A method, apparatus and article of manufacture for modifying printing based upon direct on-the-fly media characteristic parameters is disclosed. The present invention on-the-fly directly measures a media characteristic parameter and performs real-time print modification in response thereto. The measured characteristic parameters include paper texture and composition, as well as adhesion and penetration of print. The modification of print in response to these measured parameters may allow a customer to maintain observed print quality with lower-cost materials. Adjustments may include the addition of coating, hot rolling, or adjustment of toner concentration. Measured parameters may include mottle, paper texture, and bleed through.

Assignee:

International Classification:

G06F 1500

US Classification:

358 113

Abstract:

A Thin Layer Protocol. TM. adds three new data stream commands--the WOCC, WOC and END commands--to the Intelligent Printer Data Stream. TM. ("IPDS. TM. ") structured page description language. The WOCC command creates a container for encapsulating a foreign print object, such as a PostScript. TM. or PCL. TM. command stream The container includes information identifying the type of object it contains. The WOC command provides the foreign print object data for the container and includes information defining the length of the object. The END command unambiguously locates the end of the container to prevent confusion of encapsulated binary data with escape sequences. Long objects are partitioned using separate WOC commands, each providing the length of its partition. The object type information enables the printer to easily invoke an appropriate language interpreter. Alternatively, the printer may use the object type and object length information to skip over an object which it does not recognize.

International Classification:

G06T 1500

US Classification:

395114

Abstract:

A printing system wherein a first print driver utilizes an Intelligent Printer Data Stream (IPDS) to send a first job at a first font resolution to a printer and a second job at a second font resolution or a second job utilizing a non-IPDS data stream to the printer. A second print driver also utilizing the IPDS data stream is connected to the same printer for sending a third job. By sending a "Manage IPDS Dialog (MID)" IPDS command to the printer upon conclusion of the first job, the printer is enabled to switch immediately to the second job. The printer is enabled to switch between the first and second print drivers by use of the MID command at the conclusion of a print job.
