Xiaomi’s portable photo printers have become incredibly popular because of their compactness and ease of use. These devices, such as the Mini Photo Printer 1S or Portable Photo Printer, allow you to instantly print pictures from a smartphone in 3-inch format. However, many users have difficulties during the initial setup and pairing of gadgets. Unlike classic office MFPs, complex drivers or Wi-Fi routers are not required, but there are some nuances of working with Bluetooth protocol.
The process of connecting a device to a mobile phone takes only a few minutes, if you know the correct algorithm of actions. The main control application is Mijia (or Mi Home), which acts as the central hub for the entire ecosystem of the Chinese manufacturer’s smart home. It is important to understand that the printer does not connect directly through the standard Bluetooth menu in the Android or iOS settings, but requires the mandatory use of proprietary software to transfer data and adjust printing parameters. In this article, we will analyze each step in detail, eliminating common errors.
Print quality and speed are directly dependent on the correct connection and battery charge of the printer itself. Before setting up, make sure that your mobile device has a stable Internet connection for initial profile downloads and the printer is fully charged. It is critical to use the original USB-C or Micro-USB cable, since cheap analogues may not provide enough current to activate the wireless module. Below we will consider a detailed algorithm for successful start.
Preparation of equipment and compatibility check
The first step before you try to synchronize is to physically prepare the devices, so you have to remove the printer from the box, remove all the protective films, and most importantly, insert a special device. ZINK-Without the inserted paper block, the device may fail to turn on or go into error mode as sensors check for consumables. Once turned on, the indicator should light up with a straight light or start flashing, signaling readiness for pairing.
Next, check the compatibility of your smartphone. Xiaomi printers support Android operating systems version 5.0 and higher, as well as iOS version 9.0 and higher. For iPhone owners, it is important to make sure that geolocation services are enabled, since iOS requires permission to access GPS to search for devices using Bluetooth Low Energy. On Android, it is also desirable to enable geolocation, although in some versions of the OS this requirement is less stringent, but for stable operation of the BLE module (Bluetooth Low Energy) it is necessary.
Make sure your phone has Mijia installed, which can be downloaded from official Google Play or App Stores. If you have an international version of the printer, the region in the application can be set automatically, but for Chinese versions of devices (which often happens when ordering from marketplaces), you will need to change the region in the app settings to China. This is a common reason why users can not find the device in the list of available devices.
⚠️ Warning: Don't try to tuck the printer through the standard Bluetooth menu in your phone's settings. If you see the device in the list of available but can't connect, that's OK. Pairing takes place exclusively inside the Mijia app.
Installation and configuration of the Mijia application
Once you download and install the Mijia application, you need to log in. This will require a Xiaomi account (Mi Account). If you do not have one, it will take no more than a minute: you will only need a phone number or email. Once you log in, the application can request permission to use Bluetooth, geolocation and local network - be sure to confirm all requests, otherwise you will not be able to find the device.
The interface of the app may seem overloaded, but we only need the main tab. In the upper right corner is the + icon to add a new device. Click on it and the system will automatically search for Xiaomi gadgets within range. At this point, turn on the printer, holding the power button for 2-3 seconds. The indicator should start flashing, going into detection mode.
If the automatic search failed, you can use manual addition. In the list of categories, select Camera and Photos or search for your printer model, such as Mini Photo Printer 1S. The application will offer instructions for activating the pairing mode, which usually consists of simultaneously pressing the power button and the print button (or power button, depending on the model).
💡
If the app is looking for a device for a long time, try rebooting Bluetooth on your phone: turn off, wait 5 seconds and turn on again. VPN-Services that can block local search.
Step-by-step instructions for connecting to a smartphone
When the app detects the printer, a device card will appear on the screen with a suggestion to add it. Press "Add" or "Connect." The process of establishing the handshake signal can take from 5 to 15 seconds. At this time, a system window with a confirmation code may appear on the phone screen - check the numbers on the smartphone screen and on the printer screen (if any) or simply confirm the action if the code does not appear.
Once the app is successfully connected, it will prompt you to update the device’s firmware. Firmware updates often contain patches to improve Bluetooth connectivity and color processing algorithms. You can’t interrupt this process: make sure the phone and printer are charged and the internet connection is stable.
The final step is calibration. When you first install the paper or after you update the firmware, the printer may suggest calibration, which is a standard procedure that takes about a minute, during which the device prints the test strips and reads them to adjust the print density, so you don't have to drop the calibration, otherwise the colors in the photos can be distorted.

Set up the parameters of printing and paper
Once the device is on the "My Devices" list, you can go to fine-tuning. Enter the printer menu by clicking on the printer icon. Here are the basic options: paper size selection (standard for mini printers — 3x2 ounce 50x76 mm), type of layout and quality of printing. ZINK-It is important to correctly specify the type of material if the application does not automatically determine it.
Special attention should be paid to color settings. The photo editing menu has filters similar to those on Instagram, as well as manually adjusting brightness, contrast and saturation. Xiaomi printers use ZINK (Zero Ink) technology, where color is manifested by heat. So white balance and exposure play a key role. Experiment with settings, taking test shots to find the perfect profile for your batch of paper.
You can also activate the print in the settings. AR-If you turn this on, a special code will appear on the printed photo, and if you hover the smartphone camera over this code through the Mijia app, the static image will come alive, and you will play the video or audio that was attached to the photo at the time of printing. It’s a unique feature that makes albums interactive.
| Parameter | Description | Recommended value |
|---|---|---|
| Paper size | Format of consumables | 3x2” (50x76 mm) |
| Quality. | Dye-deposition density | Standard/High |
| Fields | The presence of a white frame around the photo | Optional (12 mm) |
| AR-code | Adding augmented reality | Included (for video) |
Printing photos and working with functions
To print, open the Mijia app, select your printer, and click the Print Photo button. You can select an image from the phone gallery or take a picture directly through the app interface. Before you send it to print, you will have the option to crop the frame, apply a filter or add text/stickers. The editor interface is rich enough to allow basic retouching.
The printing process takes an average 40-50 And when you leave the printer, the photo can look pale -- that's the normal reaction of thermochromic paper -- the colors appear completely within the printer. 1-2 Do not rub the surface immediately after printing, so as not to lubricate the layer that has not yet appeared.
Print Documents is also available, but it is limited. You can print text files or simple diagrams in black and white (or sepia), but the text quality will be inferior to laser printers due to the specifics of the specifics. ZINK-For printing documents, it is better to use the black and white mode in the color settings to save the resource of colored layers of paper.

Solutions to Connection Problems and Errors
Despite the simplicity, users often run into problems, and one of the most common is "Device not found." 90% of the time, it's done by checking the app's Bluetooth access rights and geolocation, and it also helps by cleaning the Mijia app cache or reinstalling it completely, and sometimes the printer freezes in standby mode, in which case it needs to be turned off, wait 10 seconds and turn it on again.
Another common problem is that you interrupt printing or you get a No Paper error, even though the block is inserted, which may mean that the chip on the block of paper is not being read. Try removing the block and inserting it back before you click. If the error persists, wipe the chip contacts on the block of paper with dry soft cloth, and the problem may be the weak charge of the printer battery.
If the print quality deteriorates (strips or white plaque appear), calibration is necessary. In the device menu, find "Service" or "Maintenance" and select "Calibration". The printer will run a few sheets to clean the heat head. If this does not help, perhaps the thermal head is contaminated - gently wipe it with a cotton swab dipped in alcohol (only when the device is turned off and cooled!).
⚠️ Note: If the printer indicator flashes red 3 This is a heat-control signal, let the device cool down for a while. 15-20 minutes before continuing printing.
💡
Most connectivity problems are solved by restarting the Bluetooth module on the phone and rechecking the permissions for the Mijia app in the OS settings.
