Surely it’s current draw? Wouldn’t the printer always operate at line voltage?

- nbernard 3y agoDepending on your supply (for instance in an old house), the printer current consumption can cause a voltage drop on nearby circuits, and this voltage drop can in turn trigger the UPS.
- anonomousename 3y agoYes. The voltage alarm in this case would be the voltage dipping too low (voltage sag) due to high current.
