Printing from an Android phone to a Samsung printer via USB cable

Printing documents and photos directly from a smartphone is a task that just a few years ago seemed complicated, requiring the mandatory use of a computer as an intermediary. However, modern technologies and the development of the ecosystem Android have made it possible to simplify this process to just a few touches of the screen. For technology users, this feature is implemented especially deeply, since the South Korean giant provides its own tools and support for its peripheral equipment. Using a wired connection via Samsung this feature is implemented especially deeply, as the South Korean giant provides its own tools and support for its peripherals.

Using a wired connection via USB cable is often preferable to wireless methods such as Wi-Fi or Bluetooth. The cable ensures stable data transmission without delays, does not depend on the quality of the router signal and allows you to print even in the absence of a local network. This is especially true when working with large files, high-resolution scans, or in offices with strict requirements for the security of information transfer.

In this detailed guide, we will go through all the stages of setup: from choosing the right adapter to installing specialized plug-ins. You will learn which printer models are supported, how to activate the print service, and what to do if the device is not detected by the system. We will also touch on the nuances of working with different versions of the operating system and specific settings for series devices MFP.

Preparing equipment and checking compatibility

The first step before attempting to connect is to thoroughly check the physical compatibility of your devices. Not all smartphones and not all printers are able to “understand” each other without additional settings. The critical element here is whether your phone supports USB OTG (On-The-Go) technology. This feature allows the mobile device to act as a host, supplying power to external peripherals.

Most modern smartphones Samsung Galaxyreleased over the past 5-6 years have built-in OTG support. However, older budget models or devices from other manufacturers may not have this feature in hardware. You also need to make sure that the printer itself is ready for use: it must be plugged in (since the power from the phone is usually not enough to operate the printing mechanism) and filled with consumables.

Particular attention should be paid to the type of connector. If your phone is equipped with a USB Type-Cport, and the printer has a standard USB Type-B (square) connector, you will need a special adapter. Direct connection is not possible without the appropriate adapter. Ignoring this requirement will result in the system simply not recognizing the connected device.

⚠️ Attention: Do not try to connect the printer to the phone if the smartphone battery is less than 20% charged. The process of initializing the drivers and preparing the printing mechanism may require significant current, which will lead to the phone suddenly turning off.

Required OTG cables and adapters

Physical connection is the foundation of the entire operation. An error in cable selection can negate all software settings. To connect a smartphone based on Android to a printer Samsung you will need an OTG adapter cable. At one end of such a cable there is a plug suitable for your phone (Micro-USB or Type-C), and at the other there is a full female USB-A connector (female).

You then insert a standard cable from the printer into this USB-A connector. The quality of the adapter itself is important. Cheap Chinese analogues often have poor shielding or poor-quality pinouts, which leads to an unstable connection. When transferring large amounts of data to print photos, this may result in a communication breakdown in the middle of the process.

It is recommended to use original accessories Samsung or certified third-party brands such as Baseus or Ugreen. They guarantee support for the necessary data transfer protocols. If you have the opportunity, check the operation of the adapter with another device, for example, a flash drive. If the phone sees the flash drive, it means that the OTG port is functioning correctly.

The connection diagram is as follows:

• 🔌 Insert the plug of the OTG cable into the charging connector of your smartphone.
• 🖨️ Connect the printer's standard USB cable to the USB-A port on the adapter.
• ⚡ Make sure the printer is plugged in and in ready mode.
• 📱 Unlock the phone screen and wait a few seconds until the notification appears.

Activating the print service on Android

After physically connecting the devices, you need to configure the software part. The operating system Android has a built-in printing framework, but it may not be activated by default or may not have the necessary drivers for a particular manufacturer. In smartphones Samsung this function is deeply integrated into the shell One UI.

First, go to the main settings of your device. The path may differ slightly depending on the firmware version, but the logic remains the same. You need to find the section responsible for connections and peripherals. It is here that the system controls all external devices, from headphones to printing machines.

Find the item Connections and go to it. Next, select the option Advanced settings. This menu hides a key element - Print service. By clicking on this item, you will see a list of available plugins. By default, only “Save as PDF” or cloud services like Google Cloud Print (which is now outdated) may be active there.

Settings → Connections → Advanced settings → Service print

In the list of available services you need to find the plugin from Samsung. It may be called Samsung Print Service Plugin or simply Samsung Printer. If it is installed but turned off, activate the switch opposite it. If the plugin is not in the list, you need to download it.

Installing and setting up Samsung Print Service Plugin

If The built-in plugin is insufficient or missing; manual installation of a specialized application will be required. The company Samsung distributes its driver through the official application store Google Play Market. This ensures that the software is secure and compatible with the latest versions. Android.

Open the application store and search for “Samsung Print Service Plugin”. Make sure that the developer indicates the company Samsung Electronics Co., Ltd.to avoid installing fakes. Download and install the application. After installation, return to the menu Print Servicethat we talked about in the previous section.

The plugin should now appear in the list. Click on the plugin name to enter its detailed settings. Here you can control the operating mode. Make sure the switch is in the Onposition. Also in this menu, the “Search for Printers” option is often available. Run it so that the system will try to automatically detect the connected USB device.

Sometimes the system asks for permission to access the USB device. A pop-up window will appear asking you to allow the application to access the printer data. Be sure to click OK or Allow. Without this confirmation, the driver will not be able to initialize the connection, and the printer will remain invisible to the system.

⚠️ Attention: The settings interface may change after updating the One UI firmware. If you cannot find the “Print Service” item, use the search in your phone settings by entering the word “Print” in the search bar at the top of the screen.

The process of printing documents and photos

When the equipment is connected and the drivers are configured, you can proceed to the printing process itself. The operating mechanism is the same for most applications in the ecosystem Android. Whether it is a browser Chrome, a photo gallery or an office suite Microsoft Office, the algorithm of actions is almost identical.

Open the file that you want to print. This could be a web page, a document PDF or an image from a gallery. Click on the menu button, which is usually indicated by three dots (vertical or horizontal). In the list that opens, find the item Print. In some applications, it may be hidden in the “Share” submenu.

After clicking on “Print”, a system preview window will open. At the top of this window you will see a drop-down list of printers. By default, “Save as PDF” may be selected there. Click on this list and select your printer Samsung. It should be displayed indicating the model, for example Samsung M2070 Series.

Before starting mechanism, it is recommended to check the print settings. Click on the gear icon or down arrow to expand additional settings. Here you can select:

• 📄 Paper size: Make sure you select the size that matches the paper loaded in the tray (usually A4).
• 🎨 Color: Switch between color and black and white printing to save toner.
• 🔢 Number of copies: Indicate the required number of copies of the document.
• 🔄 Orientation: Select portrait (vertical) or landscape (horizontal) orientation.

After checking all the parameters, press the big button with printer image. The smartphone will send the data to the device. The activity light on the printer display may light up, and the mechanism will begin to warm up and pick up paper. Do not disconnect the cable until printing is complete.

Diagnosing problems and eliminating errors

Despite the simplicity of the technology, users may encounter a number of difficulties. The most common problem is that the phone does not see the printer. In this case, the first thing to do is check the physical connection. Try disconnecting and reconnecting the OTG cable. Sometimes the contact oxidizes or does not fit completely.

If the physical connection is fine, the problem may lie in the file system format or drivers. Some older printer models Samsung require specific plugins. Go to Google Play and look for a plugin specifically for your series of printers, for example Samsung Printer Plug-in for MFP.

It’s also worth checking the developer settings on your phone. In rare cases, USB Debugging may conflict with Host mode. Try disabling debugging in the menu For Developers. Also, make sure your phone is not in power saving mode, which may limit power supply to the USB port.

Symptom	Possible Cause	Solution
The printer does not appear in the list	Plugin is not installed	Download Samsung Print Service Plugin
No connection error	Faulty OTG cable	Replace the adapter with a known good one
Printing is distorted	Incorrect driver	Select a universal driver in the plugin settings
The phone discharges quickly	High current consumption	Use a hub with external power supply

⚠️ Attention: If, when connecting, the phone makes a device connection sound, but the printer does not appear in the print list, try restarting both devices with the cable already connected. This will help reset the USB protocol stack.

Secret diagnostic mode

On some Samsung printer models, holding the Cancel button for 5 seconds when turning on the device puts the device into self-diagnosis mode, which may display an error code on the small display.

Advanced features and quality settings

For those who require professional print quality, standard settings may not be enough. The plugin Samsung Print Service allows you to delve into the technical details of the process. In the advanced settings, you can change the print resolution (DPI), which directly affects the clarity of text and the detail of images.

A scaling function is also available. If the document does not fit on the entire page, the system may offer to automatically reduce it (“Fit to Page”) or trim the margins. For photo printing, it is important to turn off automatic color correction if you want results that exactly match the original on the screen.

Some advanced models support printing directly from cloud storage via a plug-in, even without opening files on the phone. You can log in to your account Samsung Cloud or Google Drive directly in the print service interface and select a file to send. This saves space in the internal memory of the smartphone.

Frequently asked questions (FAQ)

Can I print via USB if the printer does not have a screen?

Yes, having a display on the printer is not necessary for printing via USB. Control is carried out entirely from a smartphone. The main thing is that there are status indicators (LEDs) on the printer body, signaling readiness or error (for example, out of paper).

Does my old Samsung phone support cable printing?

It depends on the model. Phones released before 2015 may not support USB OTG technology in hardware. Check the specifications of your model on the official website or try connecting a regular USB flash drive via the same adapter - if it is detected, then the printer should work.

Why is printing very slow compared to a computer?

Data processing speed on mobile processors when printing large graphic files may be lower than on a PC. Additionally, the mobile USB protocol may have bandwidth limitations in host mode. For text documents, the difference is unnoticeable.

What to do if the printer prints “cracking” instead of text?

This is a sign of driver incompatibility or file corruption. Try saving the document as a PDF and printing it as an image. Also make sure that the correct font language and encoding are selected in the plugin settings.

Is it possible to charge the phone while printing via OTG?

In the standard configuration (OTG cable), the port is occupied by the printer and charging is not possible. However, if you use a special USB hub that supports Pass-through charging, you can connect the charger to the hub at the same time as the printer.
