A computer readable device storing instructions configured to be executed by a control unit of a terminal device, the instructions, when executed by the control unit, may cause the control unit to function as a display controlling module, an identification information acquiring module and a supplying module. The display controlling module may be configured to cause, upon a user's first operation on a first file prepared for an application software installed in the terminal device, a display device to display an identification information designation screen for designating printer identification information so as to identify a printer to perform printing for the first file. The identification information acquiring module may be configured to acquire the printer identification information designated via the identification information designation screen. The supplying module may be configured to supply the printer identification information and first target data for the first file to a server.
