Document processing system with one-key printing and control method thereof

A document processing system with one-key printing, comprising:

• a printing device;
• a scanning device disposed on one side of the printing device and provided for inputting a scanning image;
• an interface module provided for inputting commands or outputting information;
• and
• a processing device electrically connected to the printing device, the scanning device and the interface module respectively;
• wherein the processing device receives the scanning image, and performs a printing process based on the scanning image, so that the printing device performs printing, and generates a prompt information when the scanning image having been stored through the interface module;
• the processing device determines whether a one-key execution command input by the interface module is received after generating the prompt information;
• when the processing device determines that it receives the one-key execution command, the processing device performs the printing process again based on a stored scanning image, so that the printing device performs printing again, when the processing device determines that the one-key execution command is not received, the processing device is in a waiting state, and if the scanning device does not input a new scanning image, the processing device continues to determine whether the one-key execution command is received.
