Abstract
Systems and methods disclosed permit flexible optimization of printer cache memories by specify criteria for determining cache membership for objects derived from a print data streams, wherein the objects may be associated with distinct reference counts. In some embodiments, the method may comprise the steps of: assigning an initial value to the reference count associated with an object, if the object is not present in the cache; incrementing the reference count by a first weight, if the object is already present in the cache; decrementing the reference count by a second weight, in response to an end-of-page event; and removing the object from the cache if the reference count is below a threshold.
