Comparison Epson SureColor SC-T3405 vs Epson SureColor SC-T3200

The highest image resolution the plotter is capable of printing on paper. It is indicated by the number of dots per inch horizontally and vertically — for example, 1440x720.

The higher the resolution, the smoother the printed image will be as a result, the less noticeable individual dots will be on it (to the point that they cannot be seen at all with the naked eye). On the other hand, the ability to print in such resolutions affects the price of the plotter accordingly. In addition, do not forget that high-quality printing requires appropriate source materials — the quality of the print cannot be higher than the quality of the original image.

Note that in this case we are talking about the maximum resolution; usually in the settings it is possible to set more modest parameters.

Approximate time taken by the plotter to print one sheet.

This indicates for the paper size that the machine was originally designed for (see "Paper Size"). And it is approximate because it is usually given for optimal or almost optimal printing conditions: low quality and resolution, relatively simple images, etc. So the actual print time of the sheet may differ from the claimed one in one direction or another, depending on the operating parameters — starting from the mentioned quality and resolution to the type of media. However, according to the figures indicated in the specs, it is quite possible to evaluate different models and compare them with each other: the difference in the claimed time, usually, will proportionally correspond to the difference in the actual printing speed.

It is also worth noting that this time is usually indicated by the duration of the printing process itself — from the capture of the sheet by the feeder to the output of the completed print from the device. Interruptions inevitably occur between printing individual sheets, so that the total printing time is longer than the printing time of a sheet multiplied by the number of sheets. For example, a device with a time consumption of 36 sec per sheet theoretically should print about 100 sheets per hour (1 h = 3600 s, 3600/36 = 100), but in fact such a plotter usually produces about 70 – 75 sheets in this time.

The largest roll diameter that can be installed in a plotter with roll printing (see above). This parameter is useful primarily for the selection of media: the material of the same width can be produced in rolls of different diameters.

Data transfer supported by the plotter.

In addition to direct connection to a PC via USB, supported by the vast majority of such devices, connection to PC network is very popular nowadays — usually via a wired LAN port, and often via Wi-Fi. The last one may additionally support special modes of operation — Wi-Fi Direct and/or . You can also find plotters with support of external media — in the form of a card reader or its own USB port for flash drives.

Here is a more detailed description of each of these options:

— Connection to a PC (USB). Connecting to a standard USB port on a PC or laptop is a classic data transfer format found in almost all modern plotters. It allows you to send print tasks to the device, manage settings, receive various operation notifications on your PC, save digitized materials from the built-in scanner (if available — see above), etc. The disadvantages of this connection include the fact that it is designed for interaction between the plotter and only one specific PC. Anyway, you can also manage a network sharing on this PC — but this is quite complicated; it is easier to immediately select a device with network connectivity (see below).

— Network connection (LAN).... LAN connection via wired LAN interface. By itself, network connectivity at least makes the plotter accessible from any PC on the local network; and some models even allow to be used over the Internet. In addition, such devices may provide various specific network functions — for example, sending materials from a scanner to file storage or e-mail. A wired connection is not as convenient as Wi-Fi — in fact, because of the need to run a wire — but it is cheaper, and it also provides a more stable and reliable connection, not dependent on obstacles and interference levels near the device.

— USB (for flash drives). USB port for connecting various external media, installed in the plotter. In addition to flash drives, this connector can be used for external HDDs, as well as for cameras and many other portable devices with built-in storage. In any case, such a connection is mainly used for direct printing — sending files for printing without using a PC. And if you have a scanner (see above), you can also copy scanned materials to an external device via the USB port. Navigation through the contents of external media is usually carried out using the display installed on the plotter.

— Card reader. Built-in memory card reader — most often SD format (although specific types and volumes of supported cards should be clarified separately, since the SD standard covers several subspecies of media). The use of this function is generally similar to the USB port for flash drives described above — it makes it possible to print files directly from external media, as well as save data received from the scanner (if available) to this media. Memory cards are now supported in many types of electronic devices — in particular, laptops are almost always equipped with card readers, and in digital cameras this type of media is used as a standard for saving footage. Accordingly, the presence of a card reader in the plotter facilitates data exchange with such equipment: removing and inserting a card is often easier than copying materials to a computer or fiddling with a direct USB connection (if it is available at all).

— WiFi. The presence of its own Wi-Fi module allows the plotter to connect to PC network, as well as use special features such as Wi-Fi Direct and Airprint. See below for such features; as for the network connection, it provides all the same features as the wired LAN standard described above. At the same time, a Wi-Fi connection is much more convenient, as it allows you to do without laying cables. True, such a connection is somewhat more expensive, besides, the data transfer rate may drop with an abundance of interference; however, for plotters, the last one is most often not critical, and the price of a Wi-Fi module is often insignificant compared to the price of the entire device. So most modern network models support not only wired, but also wireless connections.
Specifications may also specify the Wi-Fi standard used by the device; most often it is Wi-Fi 4 or Wi-Fi 5. However, the difference between these standards in this case is not fundamental: both of them provide sufficient speed for functions implemented in plotters, and modern wireless equipment usually provides compatibility with all major Wi-Fi standards .

— WiFi Direct. A feature found on models with built-in Wi-Fi modules (see above). Direct support allows you to connect other Wi-Fi devices (laptops, smartphones, cameras, etc.) to such a plotter directly, without using a router and a local network. This can be especially convenient if there is no network equipment, or if it needs to be additionally configured. The set of functions available with this connection includes, at least, sending materials to print; however, control of plotter settings and other more specific features may also be provided.

— AirPrint. Wireless direct printing technology found on Apple devices such as iPhones, iPads, MacBooks, and more. AirPrint printing is convenient and simple—it requires no additional setup when connected to a plotter and can be done with just one touch ". In this case, communication with the printing device is carried out via Wi-Fi directly — similar to the Wi-Fi Direct described above (in fact, AirPrint is usually provided as an addition to this mode).

The number of individual cartridges the plotter needs to operate.

Each cartridge is responsible for its base colour used in printing. Monochrome plotters (see "Output Type"), by definition, use only one cartridge, for black colour and for such devices this parameter is usually not specified at all. But in colour printing, where all available shades are obtained by mixing basic colours, the number of such colours (and, accordingly, cartridges) can be different.

The most modest of modern colour plotters are designed to work with 4 or 5 cartridges. The first option corresponds to the CMYK colour scheme with 4 basic colours — this is the minimum required for full colour printing. In turn, 5 cartridges usually mean a CMYK colour scheme, supplemented by a separate supply of black ink for monochrome images — this allows you not to waste consumables for such images that may be needed for colour prints, and also to print monochrome even with empty colour cartridges, and vice versa.

In general, these sets of basic colours are inexpensive, while they are able to provide fairly good quality prints; so plotters for 4 – 5 cartridges are very popular nowadays. However, the use of additional basic colours can significantly increase the quality of the image, primarily the reliability of colour reproduction. Thereby, advanced plotters can provide a larger number of cartridges — 6 – 10, and s...ometimes more. Such devices are quite expensive and difficult to maintain, but they are indispensable for printing materials with high requirements of colour quality.

The type of display provided in the design of the plotter.

The presence of the display significantly expands the control capabilities, makes it more convenient and with visual appearance. Such a screen can display at least various information about the operation state of the device; and in many cases it is also used for specific functions — direct control of plotter settings, selection of materials for printing from a USB-drive or card reader (see "Data transfer"), etc. Thereby, models that do not have display at all, are extremely rare nowadays; usually they are units with the most basic functionality, as like "only printing and nothing more." In other cases, the types of displays can be as follows:

— Monochrome. Single colour (usually black and white) display. Such displays usually also have a rather modest resolution, so their capabilities are severely limited compared to colour ones. However, this option is somewhat cheaper, but in this case this is its only advantage. Therefore, devices with monochrome display are not very popular nowadays.

— Colour. A display capable of rendering different colours. The specific quality of colour displays can vary from the simplest panels with a couple of hundred (or even tens) shades, to high-end solutions that are not inferior to PC monitors. However, anyway, the colour display has more extensive possibilities than monochrome. So, among other things, it can be used t...o preview images before printing, and they will look quite authentic. Such equipment costs more than monochrome panels, but this difference is usually not fundamental compared to the cost of plotters in general. So most of these devices nowadays are equipped with colour display. Such a display also often made with a touch screen(see below), although there are also traditional, non-touch colour displays.

— Touch screen. A touch screen similar to those used in modern tablets, which allows you to manage the device by touching the image on the display. Such control is often much more comfortable and functional than using a panel with traditional buttons, knobs, etc.: a variety of controls (buttons, sliders, counters, interactive menus, etc.) can be displayed on the touch screen, and for each situation, you can use your own, the most optimal set of such elements. In addition, it is convenient to view graphic information on such displays (drawings for printing, data from a scanner, etc.) — the screens themselves are usually coloured and have a fairly high resolution, and sensors make it easy to change the scale and move the image in the right direction. The presence of the touch screen affects the cost of the display, but in this case this moment is not fundamental. Such displays in modern plotters are very popular: a colour display in such a device is most likely also a touch screen.

Rated power consumption of the plotter. Usually specified by the maximum value — for the print mode, when the device requires the most power.

The heavier and more performant the device, the higher its power consumption in general. At the same time, models that are similar in performance may differ in this indicator. And here it is worth proceeding from the fact that a more energy-efficient unit usually costs more, but with intensive use, this difference can quickly pay off due to energy savings.

In addition, the power consumption may be necessary for special electrical calculations — for example, determining the necessary parameters of a voltage stabilizer, a backup generator, etc.

Dimensions of the main unit of the device. For desktop models (see "Placement") this is the total size of the entire plotter, it is a spec you need to focus on while choosing a model and evaluating a place for installation. For floor-standing devices, the dimensions are indicated here without taking into account the stand, so this parameter plays a minor role and can be useful mainly for storing or transporting the device in disassembled form.
