The amount of electrical power a device uses during normal operation, expressed in watts (W). It represents the typical energy draw when the product is actively performing its intended functions and can be used to estimate operating costs or compare efficiency across similar devices.

The electrical power required by a device when it is in its ready or standby state, expressed in watts (W). This value represents the typical energy draw of the product while it is powered on but not actively performing tasks, and can be used to estimate idle consumption or compare efficiency across similar devices.

The pixel density of a printer’s output, expressed as dots per inch (dpi). It indicates how many individual printing points are used to render an image or text, affecting the sharpness and detail of printed documents.

The highest pixel density that a printer can produce, expressed as dots per inch in the format width×height DPI (e.g., 4800x1200 dpi). It indicates the maximum detail level achievable when printing images or text and is useful for comparing print quality across models.

The number of pages a printer can produce per minute when printing in colour at draft quality on standard A4 or US Letter paper. The value is expressed as a page‑per‑minute rate followed by the unit "ppm" and indicates how quickly the device can complete typical print jobs under these conditions.
