Comparison HP LaserJet Pro 4102FDW vs HP LaserJet Pro M428FDW

The number of pages the printer can produce per minute in black and white mode. Typically indicated for low print quality, higher print quality takes longer. This setting is important if you need to frequently print text documents.

Approximate number of pages that the MFP can print in black and white mode without replacing the cartridge. In fact, this greatly depends on the specs of the images to print, so the actual resource may greatly differ from the claimed one in one way or another. Nevertheless, according to this indicator, it is quite possible to evaluate the capabilities of the MFP and compare it with other models.

Types of cartridges (both black&white and colour) used in the MFP. Some models of the MFP are able to work with third-party cartridges, but this feature usually refers to undocumented, and the manufacturer's warranty applies only to specific types of cartridges. So, use third-party compatible cartridge models with caution.

Cloud-enabled MFPs allow you to work directly with cloud services without connecting to a PC.

The general point of such printing is that the documents sent for printing (and in the case of MFPs, also scanned materials) are stored on a server on the Internet. Thus, the connectivity of the printer/scanner is not limited to the local network — you can send documents for printing and receive scan results from anywhere in the world where there is access to the World Wide Web. In addition, cloud services make it easy to share access to the MFP and other people.

Note that cloud printing can also be used with MFPs, that do not have such a function by themselves — for this, you need to connect the device to a PC with the appropriate software.

Amazon Alexa, Google Assistant, Cortana. The presence of one or more of these names in the specs of the MFP means that the device is compatible with the corresponding voice assistant — a system that allows you to give commands to various devices using your voice and receive voice notifications. Note that this is usually not about the presence of an assistant in the MFP itself, but about the ability to connect the device to a gadget equipped with a voice assistant — for example, a smartphone or laptop. However, this feature provides additional convenience — it allows you to control the MFP with just your voice, without using the control panel or touch screen, in particular, to send various files to print. At the same time, you should note that the functionality of the voice assistant and the possibilities for connecting it may be limited. For example, Amazon Alexa is able to print only content directly associated with the assistant (shopping lists, calendar templates, coloring books, and some other types of materials) and does not allow you to randomly select a file for printing from a third-party source, and you need to connect a device with such a voice assistant via a local network — this cannot be done directly via USB.

— Keyboard. In this case, we are talking about a full-fledged QWERTY keyboard, like those used in computers and laptops. For basic tasks, such equipment is not required, so the keyboard is a sign of a fairly adv...anced device. Models with this function, usually, provide a network connection (via LAN and/or Wi-Fi), and also have additional tools for managing materials (sorting, sending by fax or e-mail, etc.).

— Built-in fax. Allows the MFP to receive and send faxes. Two devices are involved in such a transfer: the first scans the document and transmits information via the telephone network, and the second prints a copy of the document based on this information. Despite the popularity of Internet technologies, fax communication is still quite widely used in business. Therefore, the MFP with built-in fax can be recommended primarily for use in the office. Fax is often combined with a telephone.

— Disc label printing. This function allows you to arrange the recorded disc (Printable CD-R/RW and DVD-R/RW) as you wish. Special software can be included to the package of the MFP with such a feature to create layouts for label printing.

The maximum grammage that the MFP can print on. The grammage of the paper depends primarily on its thickness; thick paper is strong, but if it is thicker than allowed by MFP's manufacturer, the paper feeder simply cannot handle such sheets.

The colour depth supported by the MFP scanner. This setting determines the number of colour shades that the device can recognize. Therefore, the overall quality of the scan directly depends on it (although other features of the device also affect this quality).

Of course, it makes sense to be focused primarily in colour depth if you plan to intensively use the scanner for full-colour images like photos, paintings, etc. If the MFP is purchased mainly for documents, where the maximum variety of colours is the logo on the letterhead or the stamp, it barely makes sense to pay special attention to this spec.

As for the colour depth, we note that the total number of recognizable shades can be determined using the formula “two to the power of the number of bits”. For example, a 24-bit scanner will recognize 2^24 = 16.7 million colours (approximately). This value is considered quite sufficient for everyday use, and 36-bit is also sufficient for relatively simple work tasks such as printing brochures and other images that do not require high colour fidelity. But for professional work with colour, you should choose more impressive scanners; in the most advanced models, the colour depth can reach 60 bits.

The maximum noise level coming from the MFP during operation. The smaller this value, the more comfortable the use of the device. For office use, this parameter is not so important, but you should pay attention to it if you are going to use the device at home. It is easiest to evaluate a specific noise level using special comparative tables. For example, the quietest modern MFPs can operate with 34-35 dB noise level which is approximately corresponds to a muffled conversation, and the heaviest and most performant models give out up to 75 dB — this is comparable to a scream or a loud laugh at a distance of 1 m.
