Abstract: The present invention includes as one embodiment a method of ejecting a fluid onto a print media. The method includes providing an ejection head having a nozzle that is coupled to a temperature sensor and a memory device. The method further includes measuring an uncalibrated temperature of the ejection head with the temperature sensor, recalling a correction value from the memory device, applying the correction value to the uncalibrated temperature to generate a calibrated temperature, and ejecting fluid from the nozzle onto the print media when the calibrated temperature is within a predefined temperature range.

Abstract: A nozzle shield assembly includes a band of material having a tag end, a standing end, a first side, and a second side; wherein the second side is at least partially folded against itself, and the standing end is configured to cover a nozzle of a print cartridge.

Abstract: A pen adapter is configured, in one example, to include a body having an internal surface defining a set of negative datum features configured to interlock with a first set of positive datum features. An external surface of the pen adapter is configured to define a second set of positive datum features.

Abstract: A printer receives commands from a host device in association with a print request, determines if the printer's resources permit processing of the commands received from the host when in a non-discard mode, enters the printer into a discard mode when resources associated with the printer are not available to permit processing the commands and, unless a command is protocol control command, discards commands to maintain communication between the printer and the host. The printer exits discard mode when a command received from the host is a protocol control command requesting that the printer exit discard mode. The host buffers commands associated with the print request, transmits commands to the printer for printing, receives indication that the printer is entering into a discard mode and resends the commands buffered on the host to the printer when the printer indicates it has exited discard mode.

Abstract: A system and method for printing on media includes a printhead assembly, a memory, and a controller. The printhead assembly is configured to make physical print sweeps relative to print regions of the media and to print within the print regions during the physical print sweeps. The memory communicates with the printhead assembly and is configured to receive data associated with a logical print sweep. The data associated with the logical print sweep controls printing within a first print region of the media during a corresponding first physical print sweep. The controller communicates with the printhead assembly and memory. The controller initiates the first physical print sweep of the printhead assembly before all of the data associated with the logical print sweep is received by the memory.

Abstract: A nozzle tape covers substantially all of an outlet portion and an electrical contact portion of a print cartridge. At least one hole provided in the portion of the nozzle tape covering substantially all of the electrical contact portion exposes at least one electrical contact formed on the electrical contact portion. When the cartridge is installed in a print device, such as a printer, a partial electrical connection will be established between the exposed electrical contact and a corresponding electrical contact in the print device. The partial electrical connection may be used to convey a signal to an output device, such as a computer. The signal may indicate that the nozzle tape must be removed before the print cartridge will work properly.

Abstract: Embodiments of the invention involve modifying non-volatile data fields in the integral memory components of consumable cartridges (and, in some embodiments, data fields in the utilizing device memory) such that the consumable cartridges become compatible with only a small subset of utilizing devices, thereby substantially reducing their potential value to a thief or unauthorized borrower.
