Comparison Epson WorkForce M105 vs Epson WorkForce M100

The time from the receipt of a print command to the exit from the printer of the first page printed in black and white, in other words, how long after pressing the "Print" button, the user will receive the first page. Most often indicated for draft (fastest) print mode, higher quality will take longer. You should pay attention to this parameter if you often need to print small documents (on one or several pages) on the printer.

— Pigment. Ink based on pigments — solid dyes, which are diluted in the form of microparticles in a liquid filler to a state of suspension. Compared to more popular water-based inks, these formulations are noticeably more expensive, and the finished image may turn out to be somewhat less bright (compared to printing with water-based dye on the same printer). On the other hand, pigment ink gives higher detail, which is especially important for photo printing. In addition, finished images resist moisture better and do not fade as quickly in bright light — this resistance is not enough for outdoor use, but indoors such prints can be stored for a very long time.

- Water soluble. Inks based on water-soluble dyes allow achieving high realism of color reproduction in color printing, they are well absorbed into the deep layers of paper and are cheaper than pigment ink. Also, water-soluble ink does not dry as quickly in the cartridge or print head of the printer. They are recommended for use with inkjet paper - ordinary thin paper strongly absorbs dropsy, which can cause ink to show through on the back of the sheet. At the same time, water-soluble inks are afraid of moisture and direct exposure to ultraviolet rays - when water gets in, the paint “floats” on paper, and it fades under sunlight.

– Pigmented / water soluble. Some printers have a print head that allows you to print with two types of ink at once. A common case is when their black cartridge is filled wi...th pigment ink, and the color one is filled with water-soluble ink.

— 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.

Approximate noise level generated by the printer during normal operation. The decibels in which the noise level is expressed is a non-linear value, so it is easiest to evaluate this indicator using comparative tables. The quietest printers give out about 35 dB — this is the volume of a conversation in a whisper, such noise will not stand out even in a quiet library reading room. A volume of 40 dB approximately corresponds to a conversation at an average volume, according to sanitary standards, this is the upper limit of permissible constant noise in residential premises during the day. For offices, the border is slightly higher — 55 – 60 dB, this is the volume of a conversation in raised tones. And the most powerful and heavy models give out up to 70 dB — this is comparable to a noisy city street; if such a printer is planned to be used frequently, it is advisable to install it in a separate room.

In general, lower noise levels make the device more comfortable to use, but may affect performance and/or price.

The maximum power consumed by the printer during operation. The lower the power consumption, the less energy the printer consumes, the more economical it is. On the other hand, devices with lower power consumption are often less performant than their more high consumption counterparts. And for the same performance, a more economical printer is likely to cost more, but with heavy use, it can pay off in energy savings.
