User concerns caused by a time lag between issuing a command for a specific operation and the start of the specific operation are reduced without reducing the accuracy of ejection problem detection by a nozzle check process. The nozzle check execution unit of an inkjet printer monitors if a cut button is pressed while a nozzle check process is in progress, interrupts the nozzle check process if the button is pressed, and after the cutting process ends, resumes the nozzle check process and checks the nozzles that have not been tested for ejection problems.
