How to choose your printer for your compulsory travel certificates

Here is the list of important technical characteristics on which you will have to make a choice for its purchase. These will impact the purchase price but also the price of the consumables necessary for its operation:

1 – Type of printing: Laser Printer or Inkjet Printer.
This first characteristic is the most important and determines the price of each impression. Laser printing is much cheaper per sheet printed compared to inkjet printers. This printer is also easier to maintain. But laser printers are more expensive to buy.

2 – Connection to the computer: How will you connect your printer? With or without cable (USB cable, Ethernet cable, Wifi, BlueTooth).

3 – Loading paper for printing: This condition the number of sheets available in the printer, either in sheet-by-sheet mode, or 50 or 100 sheets are present to prevent printing.

4 – Loading for the Scanner option (if available): This allows you to scan entire files with your printer without cutting sheets.   

To regularly and easily print documents, such as the certificates currently required to move around, a monochrome laser printer (black, white, grayscale) with only a USB cable connection, and a single paper load (sheet by sheet) will be the best value for money / simplicity / efficiency.

Here is a selection of printers not too expensive at Fnac and Amazon that will meet your needs . And despite the containment, if most merchant sites have announced that they no longer deliver to a relay point, home delivery is still possible.

Epson printer at a very low price

This Epson printer is a 3 in 1 multifunction model: A4 duplex printing, separate ink cartridges, mobile printing function and large LCD screen.

What are the purchasing principles and directions for smart TVs

 First of all, what is most important for TV is the first, and the first is the viewing experience, which is the picture quality. The second is the experience in the use process, that is, the operation is simple and easy to use and smooth, and the film source is rich. Most of the films you want to see are available. You can install third-party software to expand the film source and function with as few ads as possible.

Therefore, the principles and directions of purchase are:

First, television image quality processing technology

Second, the hardware configuration and performance of the TV

Third, the TV’s operating system ease of use/source richness

I will focus on these three issues later.

Is smart TV graded? What is the basis?

 When purchasing a smart TV, you should focus on giving priority to picture quality. At the same time, generally speaking, the better the picture quality model, the more expensive the price, rather than the stronger and more expensive.

Therefore, the classification is mainly based on the quality processing technology of LCD TVs:

Low-end machine: no picture quality processing technology, hardware performance configuration meets basic requirements.

Mid-range machine: at least motion compensation function, hardware performance is similar to or better than low-end machine

Mid-to-high end: At least motion compensation / wide color gamut / light control partition/peak brightness 600 nits, hardware performance is similar or better than low-end machines

High-end machines: motion compensation, wide color gamut technology, checkerboard light control partition, high screen peak brightness (≥1000), high screen refresh rate (120hz), image quality processing chip, all are indispensable.

Alpha Series Washing Machine

 (1) Display design

The Panasonic Alpha series washing machine borrows from the Porsche design (yes, that is the super-running Porsche). The overall is a minimalist Bauhaus style (that is, extremely modernist style), very textured. Its display draws on the design of the five-barrel instrument cluster of a Porsche sports car. When adjusting the washing program or function, there will be a feeling of operating super-run. Below the five-barrel instrument panel is a touch screen that provides a series of touch keys for running, pausing, system settings, and opening and closing of the windows and doors, which are both simple and elegant and convenient.

(2) Inner tube

The inner tube of the Panasonic Alpha series washing machine borrows from the wheel design of the Porsche supercar. The inner wall has some protrusions, which is strong and strong, and it is very rigid at first glance.

(3) Automatic ventilator door

It is worth mentioning that the door of the Panasonic Alpha series washing machine can “breathe”. If you have the habit of washing clothes at night and waking up in the morning, then drying it, it is still very suitable, because it will automatically open a gap after washing the clothes and windows, allowing fresh air to enter, not only will not smell the clothes, It can also keep the inner cylinder dry. This is not available in the other two washing machines.

 Siemens drum washing machine

 (1) Display design

The display of Siemens drum washing machine uses an LED display, which can understand the operation of washing machines such as water temperature and speed. Touching the buttons can perform operations such as accelerated washing and energy saving washing. The specific washing program needs to be selected by its knob. The shuttle bronzing process is ok. Its washing program is divided into two columns arranged vertically on both sides of the knob, which does not feel beautiful to the individual.

(2) Inner tube

The Siemens drum washing machine uses a water-filled inner tube design, which conforms to the water ripples when washing, and the washing is relatively gentle.
