A terminal device may send a registration request to a print intermediation server. The registration request may cause the print intermediation server to register virtual printer related information. The terminal device may receive authentication information from the print intermediation server. The terminal device may send image data related information to the print intermediation server. The image data related information may be related to target image data representing a target image of a print target. The image data related information may be associated with the virtual printer related information and the authentication information in the print intermediation server. The terminal device may send the authentication information to an actual printer. The authentication information may be used by the actual printer to obtain target print data. The target print data may be data which is created from the target image data by the print intermediation server.
