20080204790 | PRINTING MANAGEMENT APPARATUS, PRINTING SYSTEM, AND PRINTING MANAGEMENT METHOD - A management apparatus receives an allocation request from a printer in accordance with a designation of a user, and reads a page count upper limit and an already-allocated page count for the user. The management apparatus calculates an allocable page count by subtracting an already-allocated page count from the page count upper limit, and if the allocable page count is greater than 0, calculates a page count allocation that is based on the printing speed of the printer and is lower the lower the allocable page count is. The printing management apparatus prints the obtained allocable page count to the printer. | 08-28-2008 |
