Abstract
The present invention provides a method and apparatus for adjusting an interval of polling a peripheral device (e.g., printer) for status information, as based on the presence of a predetermined condition. In one embodiment of the present invention, short polling intervals are used to poll a peripheral device when a station (e.g., computer system) is not receiving adequate and/or reliable notification of interrupts/alerts that occur at the peripheral device. Long polling intervals are used to poll the peripheral device when the station is receiving adequate and/or reliable notification of interrupts that occur at the peripheral device.
