In a printing system including an MFP, a memory unit pre-stores attribute information of paper sheets. In the MFP, a control panel allows the user to copy or change attribute information of a paper sheet via a key input unit or touch panel unit. An MFP controller included in the MFP controls a print unit to execute print processing using a paper sheet corresponding to attribute information stored in the memory unit under the conditions based on the attribute information. When the user inputs a print instruction designated with a paper sheet, the MFP controller checks if attribute information of the designated paper sheet is stored in the memory unit, and controls the print unit to execute printing using the stored attribute information. The control panel allows the user to select paper sheets whose attribute information has been copied or changed when the user selects print sheets.
