The invention relates to a printer. The printer comprises a communication interface, a memory, a printing engine, and a controller. Some embodiments of the present disclosure provide a method for enabling a printer to execute a file stored in a server using a memory having a relatively small storage capacity in a state that the print setting has been assigned to a file stored in the server the image of the printing technology. The use of the memory in the printer is minimized when the printer performs the printing by receiving data from the server in a state that the print setting has been assigned to the file stored in the server.
