摘要： A method for compressing data includes transmitting a requested compression factor such as a quality factor known in JPEG compression, to a scanner or like peripheral device. The type of communication link between the scanner or like device and a host computer is identified, and based on the communication link type, the requested compression factor is altered to generate a new compression factor subsequently used to compress the data. The amount of buffer, such as scan buffer, used by the scanner or peripheral device may also be used to alter the compression factor prior to compression.

摘要： A method for effecting synchronous pulse generation for use in variable speed serial communications is provided. The method includes the steps of obtaining a communication link speed; generating a difference signal representing a signal level difference between at least two data stream signals; providing a clock signal; providing a counter; defining a sample count value of the counter using the communication link speed; incrementing the counter in relation to the clock signal; and determining whether a current count value of the counter corresponds to the sample count value. If the current count value corresponds to the sample count value, then the method performs a step of generating a synchronous pulse. If the current count value does not correspond to the sample count value, then the method performs a step of determining whether a signal level of said difference signal has changed, and if the signal level of the difference signal has changed then performing a step of ignoring further changes in the signal level of the difference signal until the current count value of the counter corresponds to the sample count value at which time the step of generating the synchronous pulse is repeated.

摘要： Methods and apparatus for using isochronous data transfer mode to communicate between a host computer and a printer. Preferably, the printer receives a sufficient volume of data from the host, such as a computer, over an isochronous communications channel, to begin but not complete one print pass (i.e., line scan or page scan). Subsequently, the print pass is initiated causing a print mechanism to move a printing device relative to a substrate without interruption. Thereafter, sufficient data to complete the pass without interruption is received over the isochronous communications channel during the print pass. The high speed transfer rates afforded by isochronous data transfer allow for printing to be initiated before all of the data necessary to complete a print operation without interruption is received. Moreover, the size of a printer buffer used to store the print data before printing may be considerably reduced to store only a portion of the data needed for an entire print pass.

摘要： An apparatus and method for controlling packet generation in a bus that couples a host to a plurality of devices. The apparatus includes a host controller for use with the bus and the host. The host controller has an SOF packet generator capable of delaying the generation of an SOF packet if there is another transaction occurring in the bus until the transaction is complete, thereby to relax the frame timing of SOF packet generation sequences.

摘要： An improved signal converter is provided to interface between an IEEE 1284 (parallel) bus or device and an IEEE 1394 (serial) bus or device. The converter in its preferred embodiment is designed for use with printers, in which the printer communicates with the converter through either the converter's 1284 port or its 1394 port. In one system, the converter acts as a “1284-to-1394 converter” to interface between a printer (on the 1394 port) and a host computer (on the 1284 port). In a second system, the converter acts as a “peer-to-peer 1394-to-1284 converter” to interface between a printer (on the 1284 port) and some type of 1394 compliant device (on the 1394 port), such as a digital camera. The converter includes a Link layer that is embedded within an ASIC, which preferably includes a microcontroller or a logic state machine, to facilitate asynchronous data transfer. The ASIC acts as an interpreter between the 1284 bus and the microcontroller interface of the Link layer, and is responsible for mode negotiation and mode operation as defined in the IEEE 1284 standard. In the 1284-to-1394 converter mode of operation, the converter provides a 1284 controller in a “slave” mode, thereby allowing the 1394 side of the microcontroller to act as the controlling “master” of the converter system. In the peer-to-peer 1394-to-1284 converter mode of operation, the converter provides a 1284 controller which operates as a “master” for the printer's slave controller, thereby initiating and controlling the flow of data on the 1284 interface. Since the converter is the master of the 1284 interface, it is also responsible for reading the alerts from the printer, once the printer is “armed” to provide such alerts.

摘要： The invention is directed to a method of printing on a print medium using an ink jet printer. The ink jet printer includes a printhead assembly having a plurality of ink emitting nozzles. Ink is jetted onto the print medium from the printhead assembly during a first mode of operation using a first available set of the nozzles. Ink is jetted onto the print medium from the printhead assembly during a second mode of operation using a second available set of the nozzles, dependent upon a physical operating parameter of the ink jet printer. The second available set of nozzles has a smaller number of the nozzles than the first available set of nozzles.
