Abstract
All or necessary minimum objects are copied in an image drawing apparatus and sent to a print queue. The objects are deleted in response to a deletion command from a higher level apparatus, whereas the copied objects are deleted after a print operation. Alternatively, the objects are deleted after the print operation in response to a deletion command entered from the higher level apparatus and temporarily held. In this manner, a deletion command from the higher level apparatus is not rejected and the higher level apparatus can be released as soon as possible.
