A printing system includes an image formation apparatus for executing a print job of forming an image that has been received, and upon completing the print job, transmitting a notification of completion to the print job transmission source, and a client terminal for transmitting, to the image formation apparatus, the image formation print job based on a request from a user, and upon receiving the completion notification, alerting the user that the requested print job has been completed. When the number of print job transmission to the image formation apparatus does not match the number of completion notification receptions from the image formation apparatus, the client terminal prevents alerting the user of completion of the print job. When there is a match, the client terminal alerts the user of the print job completion, which had been prevented.
