An average ink-jet which is designed for home use will typically use 30 to 50 watts when it is printing, in standby mode most printers will draw around 3 to 5 watts of power. Commercial printers which are used in an office will draw 30 to 50 watts on standby and 300 to 500 watts when printing.
Certain printers and specifically laser printers may consume significantly more, depending on design and if a halogen lamp is used for the fuser. This may significantly increase wattage, and is not recommended to connect to a UPS (uninterruptible power supply).
