Epson LQ 630 Monochrome Dot Matrix Printer

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 amount of data that a device can temporarily store in its internal memory before processing or transferring it. The value is expressed with a digital capacity unit (e.g., kilobytes, megabytes). This attribute helps understand the performance and efficiency of hardware when handling information streams.

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.

A colour is a visual attribute that describes the hue or shade of an object or surface. It can be a single dominant colour, a combination of colours, or a range such as "Black, White". The value may be expressed in common names (e.g., Black, Silver) or descriptive terms (e.g., One Colour, Assorted).

The network and data interface technologies supported by the product, such as Wired, Wireless, USB, Bluetooth, or combinations thereof. Each value represents a distinct technology that can be used for communication or power delivery.

The linear measurement of an object from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the item is and can be used for fitting, compatibility, or spatial planning.

The vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.

The range of relative humidity (expressed as a percentage) within which the product is designed to operate reliably. Values are given as a minimum–maximum interval such as "10 to 80%" and indicate the acceptable environmental moisture level for optimal performance.

The physical or logical interface used by a device to connect with other components, such as USB, PCI Express, SATA, Ethernet, Thunderbolt, DisplayPort, or similar standards. It indicates the technology that enables data transfer and power delivery between the product and its peripherals.

A list of the printing command sets or languages that a printer can understand and execute, such as PCL, PostScript, ESC/P, PDF, and other proprietary formats.

The largest paper or media dimensions that a device can handle, expressed either as standard format names (e.g., "A4", "Legal") or as physical measurements in millimeters or inches. This attribute indicates the maximum sheet size supported by printers, scanners, copiers, and similar equipment.

The highest pixel density that a printer can output or support, expressed as dots per inch (dpi). It indicates the maximum detail level achievable in printed images and documents when printing in black‑and‑white.

The total count of individual copies that a product can produce, print, or otherwise deliver in a single operation or session. It represents the maximum number of identical units that the device is capable of handling at once, such as the number of pages a printer can copy before needing to pause or reload. The value is an integer and may be accompanied by the word "copies" for clarity.

The largest paper or media size that a printer can handle, expressed either as standard format names (e.g., "A4", "Legal") or as physical dimensions in millimeters or inches. It indicates the maximum sheet dimensions supported by the device for printing.

The highest number of characters a printer can output per second, expressed in characters per second (cps). This metric indicates the maximum throughput of the printing device and allows users to compare how quickly different printers can produce text or simple graphics.

The format or medium of a product, such as DVD, Blu‑ray, USB flash drive, paper, or other physical or digital media. It indicates the kind of material that can be used with or contained in the item.

A list of operating systems that the product can run on or is compatible with. Each entry represents a distinct OS version or family, such as Windows 10, macOS Catalina, or Linux Ubuntu 20.04. Users can use this attribute to verify that their device’s software environment meets the product’s requirements.

The count of electrical contacts or pins in the printer’s print head assembly, indicating how many separate signal lines are used to drive the printing mechanism. This number is relevant for dot‑matrix, impact, and some inkjet printers where the pin count determines print resolution, speed, and compatibility with specific ribbon or cartridge types.

The total number of characters a printer’s print head can produce before it needs replacement or maintenance, expressed as a numeric value that may include qualifiers such as "million". This metric indicates the expected longevity and durability of the print head for continuous printing operations.

A list of software programs and utilities that come pre-installed or bundled with the product, such as operating systems, drivers, antivirus suites, or other essential applications.

The horizontal measurement of a product, expressed in a linear unit such as millimetres or inches. It indicates how wide the item is from one side to the other and is used for sizing, fitting, and compatibility purposes.
