Comparison Epson EcoTank L18050 vs Epson EcoTank L810

The largest paper size that the printer can handle. Most often, the formats are marked from A0 to A10; it is from here that the famous “A4” is taken, denoting a standard landscape sheet. Modern printers can use the following formats:

A2 — 420x594, the size of a newspaper spread. The largest format used in today's consumer-grade printers. In fact, this size is rarely required, and the printers themselves are expensive; therefore models under A2 are usually high-end professional devices.

A3 — 297x420 mm (2 times larger than the landscape sheet, magazine spread). It is mainly used in the business area for printing large letterheads, brochures, announcements, posters, etc.

A4 — 210x297 mm, standard landscape sheet. The most common paper size for home and office use — usually this size is sufficient for non-specialized printing.

A6 — 105x148 mm (a quarter of the landscape sheet). Printers of this format are usually designed primarily for printing photographs — the sheet size is approximately equal to the size of a standard print of 10x15 cm.

A8 — 52x74 mm, an extremely miniature format, which is 1/16 of the popular A4 (comparable to the size of a standard business card — only a little shorter). It is found mainly among portable printers (see "Type"), including models with specific printing tech...nologies (on special paper without the use of dyes).

Note that the media format specified in the specifications is rather conditional: many printer models do not have length restrictions — the main thing is that the media fit into the width, and in some devices the actual maximum size is somewhat different from the standard sizes of a certain format.

The black and white print speed provided by the printer. It should be noted that this parameter is often indicated for low quality when the device is running at maximum performance; at a higher quality (even at standard), the actual speed can be noticeably lower, so you should choose with a certain margin. Also note that high speed significantly affects the price, power consumption and noise level. Therefore, it does not always make sense to chase maximum performance — for simple applications (for example, at home or in a small office), a relatively slow and inexpensive device may be the best choice.

As for specific values, speeds up to 20 ppm are considered relatively low, 20 – 30 ppm — average, 31 – 40 ppm — decent, and the fastest models are capable of delivering more than 40 pages per minute.

Colour print speed provided by the printer. Usually, the specifications give speed at low quality, when performance is highest; on standard and especially high settings, the print speed can be noticeably lower, so it’s worth choosing with a certain margin. It is also worth considering that high speed significantly affects the price, power consumption and noise level. Therefore, it does not always make sense to chase maximum performance — for simple applications and small print volumes, a relatively slow and inexpensive device may be the best choice.

The "slowest" colour printers today are capable of delivering less than 10 pages per minute. A more decent value is considered 10 – 20 ppm, a speed of more than 20 ppm can already be called quite good, and in the fastest models this figure exceeds 30 ppm.

Printer print speed in photographic (highest) quality. Unlike other similar parameters, in this case the speed is usually indicated for a 10x15 sheet (A6, the most popular format for photographs). In addition, photo printing speed is not expressed in pages per minute, but in seconds per page, because. printing takes a lot of time. This option is worth paying attention to if you plan to print photos frequently.

Ability to use the printer to print directly on recordable optical discs (CD-R/RW, DVD-R/RW). Thus, after recording a disc, you can put on its non-working surface (non-mirror side used for inscriptions) an inscription or image as you wish. Often these printers come with software that makes it easy to create layouts for printing on disks. Please note that only specially designed discs can be used for printing.

The maximum number of pages that the printer's ink (toner) can print. The value is rather conditional, in reality the deviations from the norm are very large (up or down). In inkjet printers, the cartridge life is relatively small and amounts to several hundred prints. In laser and LED devices, the bill is already in the thousands.

— Connection to PC (USB-B). Connecting to a PC via USB-B in printers means using the standard USB type B port found on the device body, which is used for data transfer from the computer. This port is usually used in wired printer models and connects to the PC with a USB-A to USB-B cable, where side A is inserted into the computer, and B into the printer. This type of connection provides stable communication, high data transfer speeds, and easy connectivity without network setup.

— Network Connection (LAN). The ability to connect to a local computer network via a standard LAN port (using an Ethernet cable). With such a connection, the printer becomes accessible to all computers on the network, which is very convenient for offices, coworking spaces, and other places where printing is used by different people from different computers. Note that the network connection can be accomplished either through one of the computers on the network or through a common router; in the latter case, the printer remains operational regardless of which computers on the network are currently on. Compared to another connection option — Wi-Fi — wired connection is less convenient due to the need to lay a cable; however, it is cheaper and the connection is maximally reliable.

— Wi-Fi. Wireless technology initially intended for working with computer networks, but nowadays also used for...direct communication between devices (Wi-Fi Direct see below). Typically, printers with Wi-Fi can work as network devices — when communication is via a local network, and all computers on the network have access to the printer; however, the ability for direct gadget connection is less common. Nevertheless, the specific functionality of Wi-Fi should be clarified separately in any case.

— Card Reader. A slot for reading memory cards, usually with a direct printing function (see above). In this case, this function is especially convenient because memory cards are widely used in modern photo and video cameras; thus, the card reader allows for quick and easy printing of captured materials — just remove the card from the camera and insert it into the printer. However, this function can also be useful for exchanging data with other devices — for instance, laptops; and on some printer models, it is even possible to work in an external card reader mode for a PC.

— USB-A. A full-size USB port that allows connecting various external peripherals to the printer. Most often used for direct printing from flash drives and other storage devices, but can also be used for other purposes — such as firmware updates, troubleshooting, etc. Do not confuse this function with connecting to a PC via USB-B, where the printer itself acts as a peripheral device.

— USB-C. A modern interface that replaces the classic USB-B port and provides a more compact, symmetrical, and reliable connection. This port allows quick document transfer from a PC or laptop, often without additional drivers, and is compatible with new devices including MacBook and ultrabooks. USB-C can also be used for connecting flash drives, phones, tablets.

— Bluetooth. A technology for direct wireless communication between various devices. In printers, it is mainly used for the traditional purpose — for receiving materials sent for printing from external devices. One of the advantages of such a connection is that it allows working not only with computers but also with portable gadgets like smartphones and tablets: built-in Bluetooth modules for such gadgets are almost mandatory, whereas wired connection methods are often not available at all. And it can even be more convenient to connect to a PC or laptop this way: Bluetooth requires no wires and confidently works at a distance of about 10 meters.

— NFC. A short-range wireless communication technology — up to 10 cm. In printers, it is usually used as an auxiliary function, to simplify Wi-Fi and Bluetooth connections: instead of manually setting up the connection, simply bring an NFC-enabled gadget close to the printer and confirm the connection. And in some models, materials can even be sent for printing immediately this way (by bringing the device to the printer); for this, usually, a branded application must be installed on the external gadget.

— Wi-Fi Direct. A feature found in models with built-in Wi-Fi modules (see above). Direct support allows other Wi-Fi devices (laptops, smartphones, cameras, etc.) to connect directly to such a printer without using a router and local network. This is especially convenient in the absence of network equipment, or if additional setup is required. The functionality of Wi-Fi Direct connection is generally similar to Bluetooth (see above); the main difference is that Wi-Fi provides faster and more reliable communication with greater range. This is particularly relevant for transferring large volumes of data — for example, sending large-format documents for printing. Additionally, this connection is better suited for direct printing from cameras — in such equipment, Wi-Fi is traditionally used for wireless connection.

— AirPrint. A similar feature to the one described above (Wi-Fi Direct). Allows connection to the device without involving a router. However, in this case, it refers to connecting Apple devices — iPhones, iPads, Mac laptops.

Cloud print service supported by the printer. Specified only if the device is capable of working with cloud services directly without connecting to a PC.

The general principle of such printing is that documents sent for printing are stored on a server on the Internet. Thus, the availability of the printer is not limited to the local network — you can send documents for printing from anywhere in the world where there is access to the World Wide Web. In addition, cloud-based printers make it easy to share with others.
