摘要： A roller stop for connection to the head rail of a covering for an architectural openings is releasably connectable to a rear edge of the head rail in overlying relationship with a roller having shade material thereon with the shade material having a bottom rail. The roller stop has a pivotally mounted body selectively positionable in closely adjacent but spaced relationship from the outer wrap of shade material on the roller and in a position to engage the bottom rail when the shade material is fully wrapped on said roller. A catch arm is selectively engageable with serrated teeth to releasable hold the pivotal body in a preselected desired position.

摘要： A test page, system, and method are used to set a color density level of a laser printer, by producing a dot gain test pattern. The laser printer has at least one primary color. The dot gain test pattern is self-indicating and thus requires no external reference in order to determine a correct color density level. A preferred embodiment of the dot gain test pattern includes (a) a stable pattern having a color density which is stable with respect to changes in the laser printer operating conditions, and (b) a sensitive pattern having a color density which is sensitive to changes in the operating conditions, wherein the sensitive pattern in reference to the stable pattern indicates the density level of the laser printer for the at least one primary color. Additionally, in a preferred embodiment, the stable pattern includes a uniform coarse dot pattern, and the sensitive pattern includes a gradient of fine dot densities, the gradient printed adjacent to the coarse dot pattern, wherein a correct density level of the laser printer for the at least one primary color is indicated when a mid-spectrum area of the fine dot gradient appears to blend into the coarse dot pattern.

摘要： Fine pulse width modulation (PWM) adjustments in the output of a laser printer are accomplished by receiving values from a bit map and modifying the values in accordance with values in a lookup table (LUT). The lookup table is subdivided into a plurality of blocks, and a selection of the blocks is made in accordance with external values. This allows the output of a pulse width modulation circuit to be adjusted to a precision that is greater than that afforded by the bit size of the values from the bit map. The use of plural blocks in the lookup table permits adjustments in the output of the pulse width modulation circuit in accordance with external factors such as relative humidity, sensitivity of an optical photoreceptor, and developer life.
摘要翻译：激光打印机的输出中的精细脉冲宽度调制（PWM）调整通过从位图接收值和根据查找表（LUT）中的值修改值来实现。查找表被细分为多个块，并且根据外部值进行块的选择。这允许将脉冲宽度调制电路的输出调整到比来自位图的值的位大小所提供的精度更高的精度。在查找表中使用多个块可以根据诸如相对湿度，光学感光体的灵敏度和显影剂寿命等外部因素调节脉宽调制电路的输出。

摘要： An indexed limit stop for mounting on the headrail of a covering for architectural openings is easily connected to the headrail in overlying relationship with shade material wrapped on a roller in the headrail and has two elements that are pivotally interconnected and movable between selected fixed positions. The second element includes an abutment stop for engagement with the bottom rail of the shade material when the covering is fully retracted and can be positioned such that the abutment stop is spaced from the outer wrap of shade material to avoid damage to the shade material while being desirably positioned for intercepting movement of the bottom rail to limit retracting movement of the roller.

摘要： Systems and methods for cooperative rasterization of print data in an enterprise network are described. In one aspect, a primary printer rasterizes a portion of a print job to input raster bits into a raster buffer associated with the primary printer. During print job processing operations, the primary printer identifies a potential underflow condition of the raster buffer. Thus, the primary printer communicates an un-rasterized portion of the print job to a secondary printer for the secondary printer to rasterize—the primary printer not rasterizing the un-rasterized portion. Subsequently, the primary printer receives raster bits corresponding to the un-rasterized portion from the secondary printer. The primary printer prints all of the raster bits corresponding to the print job.

摘要： A print apparatus performs a halftoning action on a raster pixel image. The print apparatus includes a super-pixel data base for storing plural n.times.n superpixels, each superpixel corresponding to a subset (or "bucket") of gray level pixel values. The method comprises the steps of: logically tiling a dither matrix across the raster pixel image and outputting a threshold value which, logically and positionally corresponds to a given image pixel value. The given image pixel value is then quantized into a selected bucket of pixel values which encompass the given image pixel value. A proportionality value is then determined which identifies the relative position of the given image pixel value within the selected bucket of pixel values. The outputted threshold value is then compared to the determined proportionality value, and the selected bucket number is incremented to a next sequential bucket number if the proportionality value exceeds the threshold value. A superpixel is next selected that is identified by the selected bucket number or the next sequential bucket number, as the case may be. A superpixel includes plural halftone pixel values and the method selects one of those halftone pixel values that is positioned at a location determinable from the coordinates of the given image pixel value. The selected halftone pixel value from the superpixel is then passed to the print engine of the printer for rendering. The method of the invention is carried out, preferably, by an application specific integrated circuit so as to enable high speed halftoning of the raster image.
摘要翻译：打印装置对光栅像素图像执行半色调动作。打印装置包括用于存储多个n×n个超像素的超像素数据库，每个超像素对应于灰度级像素值的子集（或“桶”）。该方法包括以下步骤：在光栅像素图像之间逻辑平铺抖动矩阵并输出逻辑上和位置上对应于给定图像像素值的阈值。然后将给定图像像素值量化为包含给定图像像素值的所选择的像素值桶。然后确定比例值，其识别给定图像像素值在所选择的像素值桶内的相对位置。然后将输出的阈值与确定的比例值进行比较，并且如果比例值超过阈值，则所选择的桶数增加到下一个顺序桶号。下一个被选择的超级像素被选择的桶号或下一个顺序桶号（视具体情况而定）标识。超像素包括多个半色调像素值，并且该方法选择位于可从给定图像像素值的坐标确定的位置处的那些半色调像素值之一。然后将来自超级像素的所选择的半色调像素值传递到打印机的打印引擎以进行渲染。本发明的方法优选地通过专用集成电路进行，以便能够对光栅图像进行高速半色调处理。
