The frequency of the alternating current supplied to a power supply or charger, expressed in hertz (Hz). It indicates the acceptable operating range for the electrical mains that powers the device, ensuring proper functionality and safety.

The range of alternating current voltage that the product accepts from its power source, expressed in volts (V). It indicates the minimum and maximum supply voltages compatible with the device across different regions.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

The linear dimension of the media that a device can handle, expressed as a range in millimetres (mm). It represents the minimum and maximum size of paper or other media supported by the product.

The maximum number of pages that a single black ink or toner cartridge can print before it needs to be replaced. This value helps users estimate how often they will need to refill or replace the cartridge and compare the longevity of different cartridges.

The largest standard ISO B-series paper format that a device can handle, expressed as an ISO code (e.g., "B0", "B1", …, "B5"). This attribute indicates the maximum sheet size supported by printers, scanners, copiers, and similar equipment.

A list of macOS operating system versions that the product supports or is compatible with, such as "macOS 10.15 Catalina", "macOS 11 Big Sur" or newer releases. Each entry represents a distinct OS version that can run on or be supported by the device.

The highest electrical power that a device can draw or consume during operation, expressed in watts (W). It represents the peak energy usage of the product and is useful for estimating maximum power requirements, comparing efficiency across similar devices, and ensuring compatibility with power supplies.

The maximum number of sheets a multi‑purpose input tray can hold in a single feeding cycle. This value indicates the paper capacity of the tray, helping users understand how many pages can be processed automatically before needing to refill or change the tray.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

A comma‑separated list of the network or data interface technologies that a product supports, such as Ethernet, Wireless LAN (Wi‑Fi), Serial (RS‑232/RS‑422), Parallel, Bluetooth, USB 2.0, NFC, Fiber, etc. The value may contain one or more interface names separated by commas.

A list of operating system names and versions that the product can run or support beyond its primary OS, including both commercial and open‑source distributions. Each value represents a distinct OS that is compatible with the hardware or software.

A list of natural languages in which the page description of a product is available or supported, allowing users to view or interact with the content in their preferred language.

The electrical power drawn by a device while it is in powersave mode, expressed in watts (W). It represents the minimal energy usage when the product is powered on but not actively performing tasks, and can be used to estimate idle consumption or compare efficiency across similar products.

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.

A comma‑separated list of colour names that a product can produce or display, such as black, cyan, magenta, yellow and any additional variations (e.g., photo‑black, matte black). This attribute applies to printers, ink cartridges, toner cartridges, and other printing consumables.

The expected number of pages a printer, copier or fax machine is designed to produce in an average month under normal operating conditions. It indicates the workload capacity that the device can handle without overheating or failure.

The sound intensity produced by a printer while it is in operation, expressed in decibels (dB). This value indicates how loud the device is during normal printing tasks and helps users assess suitability for quiet work environments.

A list of environmental, safety or quality certifications that a product has obtained from recognized authorities. Typical entries include RoHS, ENERGY STAR, CE, WEEE, TCO Certified, FCC, and other industry‑specific standards.

The duration from the moment a web request is made until the first black page is rendered on the screen, expressed in seconds or other standard time units. It indicates how quickly a user sees any visual content and helps assess initial page performance.

The maximum number of individual sheets that a printer or copier can accept in its input trays at one time. It represents the total page count that can be fed automatically before needing to refill, regardless of paper size or type.

The maximum number of sheets a printer can produce in a single operation or over its lifetime, expressed as a numeric value followed by the unit "sheets". This attribute helps users compare printing throughput and capacity across different models.
