Comparison HP OfficeJet 7110 vs HP OfficeJet 100 Mobile

— Portable. This category includes printers of small size and weight, equipped with their own autonomous power sources. All this makes it easy to transport the device with you and use it even in the absence of sockets. Often, these models are equipped with a Bluetooth module (see "Data Transfer") for easy connection to a laptop or even a smartphone. On the other hand, the functionality of portable printers is noticeably more modest (for example, the format usually does not exceed 10x15), and the price is higher than that of stationary ones. Therefore, you should specifically look for such a model only if mobility is important to you.

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 color palette that the printer can print. A large number of colors is required for high-quality photo printing and obtaining color prints with many shades. The standard is 4 colors.

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.

The maximum number of pages the printer can print in a month while still operating at full capacity.

The number of ink cartridges required for the full operation of the printer. In black and white devices, usually, one cartridge is installed. For colour printing, at least 4 colours are required (CMYK colour scheme), however, cartridges in such devices can be installed as 4 (one for each colour), or only 2 — black and "colour". The latter is essentially three multi-coloured cartridges in one case; This design somewhat reduces the cost, but creates certain inconveniences: when the supply of ink of one colour is exhausted, the entire colour cartridge becomes inoperative. However, this disadvantage is not critical if the possibility of refueling is provided.

Printers designed for more than 4 cartridges are also available. This design means that this model uses one of the extended colour schemes; this, on the one hand, contributes to high-quality colour reproduction, on the other hand, it significantly affects the price. In the most advanced photo printers, the number of cartridges can reach 9.

The types of cartridges (both black and white and colour) used in the printer. Some printer models are able to work with "non-native" cartridges, but this feature usually refers to undocumented features, and the manufacturer's warranty covers only specific types of cartridges. So use "non-native" models with caution.

The printer cartridge is designed for a certain service life (resource). However, the machine's compatibility with different cartridges sometimes allows you to install a higher capacity cartridge, which can result in more pages being printed. It is these models that have the option to expand the print resource that are included in this paragraph.
