Abstract
A printing device or discharge test device comprising a head that includes a nozzle discharging liquid to a medium, a temperature obtaining section that obtains a temperature related to the head, a missing-dot detecting section that detects whether or not the liquid is discharged from the nozzle, and a control section that controls the head and the missing-dot detecting section. When the temperature obtained is within a first temperature range, the head is configured to discharge the liquid to the medium and whether or not the liquid is discharged from the nozzle is detected. No such detection is made at other temperatures. When the temperature obtained is outside the first temperature range and within a second temperature range, the head is configured to discharge the liquid to the medium, and when the temperature obtained is outside the second temperature range, the liquid is not discharged to the medium.
