摘要： Embodiments of the present disclosure provide a method comprising processing a first pixel of a continuous tone image to generate a first error, the first error representative of a difference between an input level and an output level associated with the first pixel; and in response to processing the first pixel, assigning a random error to a second pixel that is neighboring the first pixel, wherein the assigned random error is independent of the first error. Other embodiments are also described and claimed.

摘要： A printer has a print head with multiple nozzles and an encoder to encode print head data into firing bits used to determine various firing patterns of the print head nozzles. A decoder is integrated on the print head to decode the firing bits into firing pulses used to fire selected print head nozzles. The encoder encodes the print head data in such a manner that there are fewer firing bits than there are possible firings controlled by the firing bits. For instance, the encoder encodes the print head data such that "n" firing bits define 2.sup.n firing levels (where "n" is an integer), with each firing level defining a different number of firings. With the multi-level encoding, the encoder is able to control more than n possible firings with each n firing bits.
摘要翻译：打印机具有具有多个喷嘴的打印头和用于将打印头数据编码为用于确定打印头喷嘴的各种点火图案的点火点的编码器。解码器集成在打印头上，以将点火位解码成用于触发所选打印头喷嘴的点火脉冲。编码器以这样的方式对打印头数据进行编码，即，比由点火控制的可能的发射更少的点火位。例如，编码器对打印头数据进行编码，使得“n”个触发位定义2n个触发电平（其中“n”是整数），每个触发电平定义不同数量的触发。通过多级编码，编码器能够利用每个n个触发位来控制多于n个可能的触发。

摘要： A printer featuring an optical data link between the printer's controller and its reciprocal, carriage-mounted printhead is described. Print data are conveyed from the controller to the printhead via a fixed point on the edge of the carriage and status data may be conveyed in the reverse direction. Power is supplied to the printhead via dual parallel rails on which the carriage is supported for reciprocation by the chassis-mounted carriage drive motor. Preferably, the optical medium is infrared light, and uses conventional driver/receiver devices.

摘要： Digital integrated circuit testable input/output pad logic includes modified output driver logic and a latch for storing a test bit provided externally at the I/O pad terminal. The output driver logic selects either the normal pad output signal (O) for output during normal operation, or the stored test bit (S) or its complement (S') for output during a test operation. The output driver logic and latch are controlled by control logic signals (DP,SP,NDN,LS,NLS,NSN) derived from common tri-state (NTR) and latch (NTM) test signals provided externally at dedicated test pins (NTR,NTM). The control logic signals are provided over a bus to all similar testable I/O pads for testing all testable I/O pads within the IC under control of the two test signals.
