The maximum distance across the widest part of a roll, expressed in units of length such as millimeters or centimeters. It indicates the largest diameter that a roll can have and is used to verify compatibility with devices, accessories, or systems requiring a specific roll size.

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.

A list of safety and regulatory certifications that a product complies with, such as CE, UL, FCC, or other regional standards.

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 the physical or logical interfaces that a device can use to connect with other devices, such as USB, Ethernet, Bluetooth, Wi‑Fi, RS‑232, RJ‑45, Parallel, and similar standards.

The range of temperatures in which a device 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.
