摘要： A print management system, includes a management unit to receive print manuscript data from a connected manuscript processor, and obtain status information indicating states of connected multiple output enabled printers; a status identification unit to predict whether the output enabled printers stop in the middle of a print job; and a print data generator to generate multiple types of print data whose amount of toner consumption during printing is different respectively, based on the print manuscript data. The management unit classifies the output enabled printers predicted that there is less possibility to stop in the middle of a print job as output candidate printers, and selects an output destination printer from the output candidate printers. The management unit selects one type of print data from the multiple types of print data, depending on the output destination printer, and outputs the selected print data to the output destination printer.

摘要： An image processing apparatus includes an edge amount calculating device configured to calculate edge amounts of an image in a plurality of directions for each of a plurality of frequency bands of the image. A character edge area determination device determines, based on the calculated edge amounts, whether or not a selected picture element of the image is of a character edge area. A sharpness control device corrects a frequency characteristic of the image by performing a first correction to the edge amounts when the selected picture element is determined to be of a character edge area by the character edge area determining device, and by performing a second correction to the edge amounts when the selected picture element is determined not to be of a character edge area by the character edge area determining device.
