What is a Xiaomi photo printer: device and capabilities

Portable instant-printing devices are no longer a rarity, but Xiaomi has been able to make this gadget affordable and stylish. Xiaomi’s photo printer is a compact device that plugs into a smartphone and prints pictures on special paper without the use of ink cartridges. This technology opens up new possibilities for creating physical copies of digital memories anywhere.

The idea behind the device is mobility and ease of use: you don't have to carry bulky equipment or buy expensive, traditional-type supplies. The mobile photo printer runs on a built-in battery, allowing you to take it on a trip, to parties or just keep it on your desktop for quick printing of documents and images.

In this article, we will take a closer look at how Zink technology works, take a look at popular brand models, and give practical operational tips, learn how to prepare the device for its first launch, and what features the company’s pre-print editing app offers.

The principle of Zink technology in Xiaomi devices

A key feature defining what a Xiaomi photoprinter is is the use of Zink (Zero Ink) technology. Unlike inkjet or laser counterparts, there are no inkwells, toners or thermal headers that need to be changed often. All the magic is hidden in the photo paper itself, which contains three layers of colored crystals: yellow, purple and blue.

The printing process is thermally driven, the printing head inside the device heats certain pieces of paper at different temperatures and durations, the crystals in the paper layer are activated and colored depending on the degree of heating, which is why the quality and speed of printing are directly dependent on the calibration of the heat head and the state of the battery.

⚠️ Warning: Do not touch the printer immediately after work. The heat head may heat up to high temperatures, which may cause burns to the fingers or damage to the sensitive surface.

It's important to understand that every piece of paper already contains all the chemicals you need to create an image, which means you can't fill your device with ink in the traditional sense, and the consumable is only 3x5-inch (or 2x3 for pocket versions) paper, which you have to buy separately.

Overview of popular models of portable printers

There are several different versions on the market, each one tailored to different use cases, a portable printer can be a pocket selfie or a more powerful device for the office and home, and understanding the differences will help you choose the right model.

The most common version is the Xiaomi Mi Portable Photo Printer, which has a minimalist white body, round shapes and weighs only 200 grams, and is ideal for printing 3x2-inch photos in AR (augmented reality) format, allowing you to “revive” photos through the camera of your smartphone.

For those who need to print documents or larger images, there is a Xiaomi Mijia Photo Printer 1S. This device supports A4 format and uses freeze-sensitive printing, which ensures photographic quality and waterproof shots. It is larger than pocket counterparts and requires network connection, but gives a professional result.

All models are connected by wireless connectivity. Wi-Fi allows data to be transmitted without delay, which is critical for printing large files or serial printing. Unlike Bluetooth, Wi-Fi provides a more stable communication channel, necessary for the transmission of detailed high-resolution images.

Instructions for connection and first start

The device takes only a few minutes to set up, but requires a certain sequence of actions: the first thing to do is to remove the printer from the package and remove all the protective films, including those inside the paper tray. Often users forget to remove the orange protective tape from the very block of the Zink cartridge, which leads to printing errors.

Then charge the device to the full level, the status indicator will show the completion of the process, then you need to download the official Xiaomi Home application or the specialized Mijia (depending on the region and model) from the Google Play store or the App Store. Registration of a Mi Account is mandatory for working with the ecosystem of the smart home.

The pairing process takes place through the device add menu. The app will automatically find the printer if Bluetooth and geolocation are enabled on the smartphone. You will be asked to enter a password from your Wi-Fi network so that the printer can work in access point mode or connect to the router. Synchronization ends with a firmware update, which is desirable not to interrupt.

⚠️ Warning: When you first install the cartridge, don't remove it until the lock clicks. If you insert the paper incorrectly, the mechanism can chew the sheet and it will not be possible to remove it without disassembling the case.

Application functionality and photo editing

Software is an integral part of the ecosystem, and it's through the Mi Home app that the magic happens, you can not just send photos to print, but you can process them, and the built-in filters, frames, stickers, and text-in addition make each image unique before it even appears on paper.

One of the most interesting features is the ID Photo mode, which allows you to take a photo of a face, automatically remove the background and replace it with the desired color (blue, red, white), and resize to the standards of documents from different countries, which eliminates the need to go to the photo show for urgent inquiries.

And you can also print collages, and you can choose a few images from the gallery, and the app will form a grid to make good use of the space on the sheet, and for Zink printers, this is especially true because the size of the paper is fixed, and it can be economically unprofitable to print one small photo per sheet.

💡

Use the AR-print function to create live cards. Record a short video or voice message, link it to a photo, and when you hover your smartphone camera over a printed photo, the video will play.

Comparison of characteristics of Xiaomi models

To make a final decision, it is worth comparing the technical parameters of different devices, the differences are not only in size, but also in speed, resolution and type of connection.

As you can see from the table, freeze-dry printing in the 1S model provides higher image quality and durability compared to Zink thermal printing, but requires stationary placement.

300 dpi is considered the standard for home photo printing, and for 3x2 or even 10x15 images, that's enough to make the image look sharp from arm's length, but when you zoom in, you can see the graininess that is characteristic of digital printing.

Consumables and cost-effectiveness

The cost of ownership of a device is not only the price of the printer itself, but also the price of consumables. Zink paper is sold in packages of 20, 40 or 50 sheets. The price of one sheet varies depending on the volume of purchase and the region, but in terms of one piece it is often cheaper than visiting a photo studio.

It is important to buy original paper or certified counterparts. Cheap Chinese copies can have an uneven layer of crystals, which will lead to stains, stripes or incorrect color reproduction. In addition, poor quality paper can leave a sticky layer on the thermal head, which will require costly cleaning or replacement of the mechanism.

⚠️ Warning: Keep unused paper in a closed package in a cool place. Moisture or direct sunlight on the pack can lead to premature activation of crystals and damage to the entire stack.

For the 1S, the consumables are cartridges consisting of a roll of paper and a cassette with a dye tape. The resource of one tape usually coincides with the number of sheets in the package (for example, 40 or 108 pieces), which simplifies the calculation: one cartridge is equal to one pack of photos.

💡

Savings are achieved when buying paper in large packages (wholesale), the cost of one picture can be reduced by 30-40% compared to buying small packs of 20 sheets in retail stores.
