A printer server is connected to a plurality of terminals. The printer server includes a terminal status detecting unit that receives a piece of operation information 'key' indicating that a operation has been performed from each terminal, measures an elapsed time since each piece of operation information 'key' was received by referring to a timer, and sets a non-operational status &#x2018;status&#x2019; for each terminal according to the length of the elapsed time, a priority determining unit that determines a priority level from the non-operational status &#x2018;status&#x2019;, and a print job processing unit that has print job processing performed by, when a plurality of print jobs are waiting to be processed, giving preference to print jobs transmitted from terminals with higher priority levels.

Printer controller that has a printer perform print processing on print jobs transmitted from a plurality of terminals, an image forming apparatus for performing print processing on the plurality of print jobs, and a terminal that transmits print jobs to the printer controller

An image processing apparatus includes a sort unit for sorting original image data into edge image data and planar image data, a first coding unit for coding the sorted planar image data according to the fractal block coding method, and a second coding unit for coding the sorted edge image data according to a coding method differing from the fractal block coding method. Thus, an image processing apparatus is provided that can have picture quality of a reproduced image improved even for a block that has maximum density difference such as an edge portion. The image processing apparatus can include a first coding unit for coding original image data according to the fractal block coding method, an extractor for extracting error between blocks, a comparator for comparing the amount of extracted error with a predetermined value, and a second coding unit for coding error information according to a coding method different from the fractal block coding method when the error amount is greater than the predetermined value as a result of comparison.
