Comparison HP DesignJet T230 vs HP DesignJet T520 (CQ890A)

- Floor. Plotters designed for installation directly on the floor, on special stands; the availability of a stand for such a device is mandatory, because it carries various auxiliary equipment – particularly, a basket for completed prints. The floor models are predominantly advanced models, which are distinguished by their large weight and size. This option is convenient because the plotter does not require additional surfaces such as tables for installation. On the other hand, such a unit can create inconvenience in tight room where there is little free space on the floor. Also note that some floor models are not equipped with stands, they must be purchased separately.

- Desktop. Plotters designed to be placed on a table, workbench, or other similar stand. This installation is good in constrained conditions, because it does not require floor space. On the other hand, it imposes some restrictions on weight and dimensions, which is why desktop plotters are usually designed for relatively small paper sizes - A2, less often A1 (see above).

The smallest drop volume of ink that can be produced by the printhead of an inkjet or similar plotter (see "Product Type").

This parameter is directly related to the print resolution (see “Maximum resolution”): the more dots per inch, the smaller the separate dots and, accordingly, the drops should be. At the same time, models with the same dpi number may differ slightly in this parameter. In such cases, it should be assumed that a smaller droplet volume potentially provides better print quality, with more accurate reproduction of fine lines and borders between individual areas of the image, however, such features accordingly affect the price of the device.

The number of rolls that can be installed in a plotter that can print from such media at one time (see above).

Most often, such models are made for one carrier, however, there are also more advanced units — for 2 or more rolls(in some cases this number reaches 4). The meaning of this functionality is that you can simultaneously use media of different sizes (for example, A1 and A2) or/and types (for example, glossy and matte paper) while printing. Of course, you can only print on one material at a time; however, the presence of multiple rolls allows you to switch between them simply through the settings of the plotter, without fiddling with changing media.

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).

Models of cartridges used in the plotter. With this info, you can easily find original consumables for the device.

The amount of built-in memory provided in the design of the plotter.

Such memory is used to store various service data: print tasks, settings profiles, etc. Due to this, the plotter becomes more "independent": for example, many models allow you to continue printing even when the master PC is turned off.

We emphasize that in this case we are talking about solid-state flash memory, which is used mainly for "operational" service information. The capacity of such memory is relatively low, it is measured in megabytes; but in addition to it, the design may include a larger storage capacity — usually a traditional hard drive. For more information about it, see "Drive Capacity".

The maximum noise level produced by the plotter during operation. The lower this indicator, the less inconvenience to others the device will create. At the same time, in modern plotters, the noise level usually does not exceed 60 dB, which is comparable to a TV set at an average volume; and many of them do not "reach" even up to 50 dB, corresponding to a quiet conversation at a distance of 2-3 m. And if we also take into account the fact that plotters are usually used in industrial premises, then we can say that in most cases this indicator does not play a significant role.

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.

The overall dimensions of the floor plotter (see “Placement”), including the stand, in other words, the dimensions of the device in the operative condition (in addition to the stand itself, other equipment, such as trays for printed materials, is taken into account here). This indicator is worth evaluating how much space is needed to install such a plotter.
