Choices relating to printing conditions which can be designated at a printing device are displayed on a display section of a host device. The choices are displayed as folders. Folder groups, in which printing conditions relating to sheet size, number of sets, double-sided/single-sided printing, N-UP printing, and absence/presence of sorting are set as names of folders, are displayed successively and hierarchically. Here, by selecting designations until a folder of a lowest hierarchy and by manipulating a file of print data into the folder, printing conditions at a time of printing the print data are designated and are transmitted to the printing device.
