Setting up a home printing network can often be a complex puzzle, especially when you need to provide access to a printer from multiple computers or laptops at the same time. USB ports on the router Keenetic Allows you to transform a regular printer into a fully-fledged network device, accessible to all devices within the Wi-Fi range. This eliminates the need to keep a single server computer running and run unnecessary cables throughout the entire apartment.
Modern routers from this brand feature a powerful operating system that handles print queue management and traffic distribution. You don't need to install cumbersome specialized software on each laptop; simply configure the router correctly and add the device to Windows or macOS. The key point is support for the LPR or Raw protocol, since not all printer models can operate in network mode without a direct connection to a PC.
In this guide, we'll cover every step: from checking hardware compatibility to fine-tuning ports in the operating system. You'll learn how to avoid common errors when the computer doesn't detect the printer and how to correctly interpret the printer's indicator lights. Let's transform your local network into an efficient workspace.
⚠️ Attention: The KeeneticOS operating system interface is regularly updated. The layout of menu items may vary slightly depending on the firmware version, so always consult the manufacturer's official manuals if you can't find the button described.
Checking equipment compatibility and preparation
The first step is to assess the technical feasibility of integration. Not every printer connected to the router's USB port will work automatically. Router Keenetic Supports a wide range of devices, but for stable operation it requires the printer to understand PCL or PostScript language, or to use standard Windows drivers. Multifunctional devices (MFPs) often cause difficulties, since the scanner is usually not accessible via the network, and only the printing function will work.
Make sure your router has an active USB port with sufficient current. Older models may not be able to handle the power required by power-hungry laser printers when the printer's oven is heating up. In this case, you'll need a USB hub with an external power supply. It's also crucial to know your printer model and whether drivers are available for your operating system, as the router itself doesn't contain drivers; it only transmits data.
Before beginning setup, we recommend resetting the printer's print settings if it was previously connected to another computer. This will help avoid IP address conflicts or queue hangups. Disconnect the device from the power source to avoid power surges when connected to the router.
Physical connection and initial setup of Keenetic
Connect the printer to the router's USB port Keenetic Use a high-quality cable. The cable should be no longer than 1.5–2 meters, otherwise signal loss and data transmission errors may occur. After turning on the router, wait 2–3 minutes for the operating system to fully load. The USB indicator on the front panel should light or flash, indicating that the device has been detected.
Now you need to log into the router's web interface. Open your browser and enter 192.168.1.1 or my.keenetic.netLog in using your username and password. Go to the menu. Applications (or USB and Bluetooth (in older versions) and make sure the "Print Server" function is enabled. The system should detect your printer model and its status.
☑️ Checking the physical connection
If the printer is detected but the status is "Disconnected," try changing the connection port or rebooting the router with the device already connected. Some models require this feature to be enabled. LPR In the print server settings. In the list of devices, you'll see the printer's assigned IP address, which we'll need for further installation in Windows.
Setting up a print server in the web interface
To ensure stable network operation, you need to assign a permanent IP address to the printer. Otherwise, when you reboot the router, the address may change, and all computers will lose connection to the printer. In the router menu, find the section Home network -> Client listFind your printer in the list and assign it a permanent IP address, or set up a static lease in the DHCP server.
An important parameter is the choice of printing protocol. By default, it is used RAW (port 9100), which is suitable for 90% of devices. If the printer is old or specific, you may need to switch to a different protocol. LPRIn this case, you will also need to specify the queue name, which often defaults to lp or iprintThis information can be found in the technical documentation for the printer.
What should I do if my printer is not detected in the list?
If the device doesn't appear in the router's USB section, try the following: 1. Check the printer's file system (some older models are not detected). 2. Use a powered USB hub between the router and printer. 3. Update your Keenetic router firmware to the latest stable version, as compatibility databases are constantly expanding. 4. Check the USB cable—it must be shielded and functional.
After configuring the print server settings, be sure to click "Save" or "Apply." The router may restart the print service, which will take a few seconds. Make sure your firewall settings don't block the ports required for printing data (usually ports 515, 631, and 9100).
Installing a Network Printer in Windows 10 and 11
Now let's move on to setting up your computer. Open "Settings" -> "Devices" -> "Printers & Scanners." Click "Add a printer or scanner." When the system informs you that the device you want isn't listed, click the "The printer I want isn't listed" link. Select the option to add by TCP-IP address or "Add printer by IP address".
In the window that opens, in the “Name or IP address” field, enter the static IP address that you assigned to the printer in the router (for example, 192.168.1.150). The system will automatically fill in the port name. Uncheck "Query the printer and select the driver automatically" if you want to select the driver manually, which is often more reliable. Click "Next" to test the connection.
| Setting parameter | Recommended value | Description |
|---|---|---|
| Device type | TCP/IP device | Standard network protocol |
| Hostname/IP | 192.168.1.x | Static address from the router |
| PnP survey | Off (manual) | To manually select a driver |
| Port | 9100 (RAW) | Standard Print Port |
If Windows can't find the driver automatically, click "Have Disk" and browse to the driver downloaded from the manufacturer's website. It's important to select the network installation option if the driver offers a choice between USB and Network. After successful installation, we recommend printing a test page to ensure the data transfer is working correctly.
Setting up printing from macOS and mobile devices
Users of technology Apple You may need to perform manual configuration, as automatic discovery via Bonjour (AirPrint) on Keenetic routers is not always reliable, especially with inexpensive printer models. Go to "System Preferences" -> "Printers & Scanners." Click "Add a printer, scanner, or fax."
In the window that opens, switch to the tab IP. In the Address field, enter the IP address of the printer. Select the Protocol LPD or HP Jetdirect – Socket (depending on what is selected in the router). In the "Queue Name" field for the LPD protocol, enter lpThe system will automatically select the software, but if this does not happen, select the model from the list or use the "Generic PostScript Printer" driver.
Android mobile devices often require installing a printing plugin from the printer manufacturer (e.g., HP Print Service Plugin). After installing the plugin, add the printer by searching by IP address. On iPhones and iPads, if the printer doesn't support AirPrint directly through the router, you may need to use third-party intermediary apps, such as Printer Pro, which can send a document to an IP address.
Troubleshooting and Frequently Asked Questions
The most common issue is "the printer is online but won't print." This is often due to a frozen Windows print service or a router buffer overflow. Try clearing the print queue on your computer and restarting the service. SpoolerAlso check if your antivirus or firewall is blocking the connection to the printer's IP address.
⚠️ Attention: If you use a guest Wi-Fi network on a Keenetic router, devices in the guest segment are blocked by default from accessing the local network and printer. To print, you must either switch the device to the main network or configure firewall rules.
Another cause of problems could be USB port formatting. Some routers work better with printers if the port isn't also used for file storage (NAS). If the printer is unstable, disconnect external hard drives and flash drives from the router, leaving only the printer connected.
In complex cases where nothing helps, try reducing the USB port speed in the router settings (if such an option is available) or updating the device's firmware. The system logs in the "Diagnostics" section can tell you whether the connection is being physically interrupted or whether there's a protocol-level error.
Why does my printer print gibberish or blank pages?
This is a classic sign of an incorrectly selected driver or protocol. If you're using a PCL driver and the printer is expecting PostScript (or vice versa), the data will be interpreted incorrectly. Try changing the driver to "Generic Text Only" to test the connection, and then install the correct model. Also, check that "Bidirectional support" isn't enabled in the port settings, as this can sometimes interfere with correct status transmission.
Can I connect a printer to guest Wi-Fi?
By default, the guest network is isolated from the local network (LAN) for security reasons. To print from guest Wi-Fi, you need to create a firewall rule in the KeeneticOS settings that allows traffic from the guest network to the printer's IP address on port 9100. However, it's easier and more secure to connect trusted devices to the main network.
Does the scanner work over the network on a Keenetic router?
In 95% of cases, no. The protocols used by routers to forward USB devices (USB over Network) are oriented toward printing (LPR/RAW). Scanning functions require two-way exchange of large amounts of data and specific drivers that a router cannot support. Scanning will have to be performed by connecting the device directly to the computer via USB.
