摘要： A method and a printing implementing the method for dynamic printer performance tuning. The method includes the steps of processing a page to be printed by a printer description language interpreter to generate a Display List, selecting tuning parameters from the Display List data, analyzing the tuning parameters by a Bayesian analyzer to obtain a score for each tuning parameter and based on the score of each tuning parameter, adjusting rendering settings of the tuning parameters for printing the page. The steps of training the Bayesian analyzer includes creating a set of training pages, rendering each page to determine best performance settings for each tuning parameter, grouping the pages based on tuning parameter settings, generating Display List data of each page, rendering the training pages in each group to compile training data that are saved for future printing jobs.

摘要： Whether rendering instructions include designation of a logical operation is determined (601). If it is determined that the rendering instructions include designation of a logical operation, then the rendering instructions are developed into multivalued bitmap data (608) every single line of the input rendering instructions and the multivalued bitmap data is subjected to color processing and binarization processing (609,610,611). When the rendering instructions do not include designation of a logical operation, color processing and binarization processing is executed (602,603,604) for every color of the rendering instructions, whereby a brush is created and stored in advance. The brush is pasted into an applicable area of the rendering instructions to achieve development into binary bitmap data.

摘要： An image processing method processes image data to be output to an image forming apparatus that is capable of making a two-way recording to form an image on a recording medium by recording in a forward path and a return path of a scan by an ink-jet recording head. The image processing method includes a halftone process that is based on an inclined line-group keytone and maintains keytone continuity, including a dither process in which the inclined line-group keytone appears at a stage where the recording in the forward path is made.

b) means for generating a set of graphics orders from the interpretted page description language commands such that:

i) said graphics orders can be processed into bands of bitmap images which can delivered to the output device at a speed required by the output device; and
