When receiving a sheet size measurement instruction through a user interface, an information processing apparatus transmits a width measurement instruction to a printer through a communication I/F. When receiving a measurement result of a sheet width from the printer, a controller extracts sheet information that meets the received measurement result and displays the extracted sheet information for user selection. When a user selection is received, the controller updates a print setting with selected sheet information. When a user selection is not received, the controller transmits a type-designated measurement instruction designating the sheet type. When the measurement result is received, the controller updates the print setting with a sheet length information included in the received measurement result.
