Appl. No.:

09/632822

Inventors:

John Booth Bates - Lexington KY
Mark Walter Fagan - Lexington KY
Richard Francis Russell - Lexington KY

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

G06K 1500

US Classification:

358 115, 358 117

Abstract:

A system and method for controlling a print job in a printer, such as canceling the print job held in the printer. The system includes a printer having a processor that receives print jobs, including one or more print data swaths, from one or more host computers, and each print data swath includes at least a predefined group of characters. The system also has at least one host computer in communication with the printer and which selectively sends print jobs including print data and/or command data. The host computer further selectively sends a command which is a predetermined group of characters within the print data swath, and the command alters a function in the printer. The command is preferably a series of identical characters, such as NULL characters, and the command preferably causes the printer to enter a command mode to execute the commanded function. The inventive method of controlling print jobs includes the steps of sending a print job having one or more print data swaths from the host computer to the printer, sending a command embedded in a print data swath from the host computer to the printer, and altering a function of the printer with respect to the print job based upon the command received. The method preferably further includes the step of sending a message from the printer to the host computer once the function in the printer has been altered, such as the print job being purged, and to request the host computer to cease sending characters which comprise the command.

International Classification:

B41J029/393

US Classification:

347 7, 347 19

Abstract:

A method of estimating an amount of ink contained in an ink reservoir includes the steps of determining a cumulative actual ink drop count of ink drops expelled from the ink reservoir; and determining an evaporation amount associated with the ink reservoir, wherein before a time threshold the evaporation amount is ignored, and upon reaching the time threshold the evaporation amount is used to compensate for an evaporation loss for the ink reservoir by adjusting the cumulative actual ink drop count to form an evaporation compensated drop count.

International Classification:

B41J019/00

US Classification:

400283, 347 37

Abstract:

A method for reducing the effects of printhead carrier disturbance during printing with an imaging apparatus having a printhead carrier for carrying at least one printhead includes the steps of accelerating the printhead carrier from a first position in a first direction; printing with the printhead in the first direction; and changing a rate of acceleration of the printhead carrier for a subsequent accelerating of the printhead carrier from the first position in the first direction prior to a subsequent printing with the printhead in the first direction to phase shift the printhead carrier disturbance.

International Classification:

G06F015/00

US Classification:

358 115, 358 11

Abstract:

A method of printing on a print medium with a printer which is in communication with a host computer includes the steps of providing the host computer with a print job to be printed by the printer, identifying a data format associated with the print job, determining an operating system stored in the printer, comparing the data format with the printer operating system, downloading an operating system which corresponds to the data format from the host computer to the printer if the printer operating system does not correspond to the data format, transmitting print data associated with the print job from the host computer to the printer, and printing on the print medium with the printer using the print data.

Abstract:

A method of obtaining information from a networked device is provided. The method includes the steps of defining a network; providing a network adapter communicatively connected to the network, the network adapter connected to the networked device; providing memory in the network adapter; updating information in the memory, wherein the information describes a status of the networked device; placing the information into a response frame; and sending the response frame in response to any command frame received by the network adapter.

US Classification:

347 19

Abstract:

An imaging system includes an imaging cartridge, a first memory associated with the imaging cartridge, and a controller communicatively coupled to the first memory. The controller executes program instructions for performing the steps of generating a generated cartridge identification number to be associated with the imaging cartridge and storing the generated cartridge identification number in the first memory.

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

B41J 2/15

US Classification:

347 41

Abstract:

The invention provides an apparatus and method for printing an image using the printhead of an ink jet printer. The printhead ejects ink drops on a print medium in a series of scanning passes, and different addressing patterns are selected in each scanning pass to address ink drop locations for different portions of the raster lines addressed by each scanning pass. Addressing patterns having various interlacing percentages are selected in order to produce overlapping boundary regions between passes. The overlapping boundary regions minimize the banding effects that occur with inexact ink drop placement.

Abstract:

A method for printing shingling print data in a shingling print pass of a multi-shingling-pass print swath. One step includes compacting the shingling print data by removing the deterministic voids associated with the shingling print algorithm. Another step includes expanding the compacted shingling print data based on the shingling print algorithm. An additional step includes printing the expanded shingling print data.
