Abstract

The present invention is intended to provide a print data transmitting device that can teach an operator a recommended print condition corresponding to a size of recording paper in a printing apparatus. The print data transmitting device is configured to include: a print condition storage part that retains a print condition specified by a user as a user-specified print condition; a print condition comparing part that compares a recommended print condition, which is obtained from print setting information including a size of recording paper and availability of double-sided printing and corresponds to the size of the recording paper, and the user-specified print condition with each other; a changing screen display part that, in the case where the user-specified print condition does not coincide with the recommended print condition, displays a changing screen that includes the recommended print condition and is arranged with a selection button for selecting the recommended print condition as a print condition; a print condition changing part that, on the basis of an operation of the selection button, changes the user-specified print condition; a print data generating part that, on the basis of a print instruction, generates print data including the user-specified print condition; and a print data transmitting part that transmits the print data.
