How to connect a USB printer to a laptop via WiFi

A situation where there is a laptop at home without a built-in print scanner and an old but working printer with an interface USB, is ubiquitous. A wired connection often creates inconvenience: you have to search for the cable every time, plug it into the port, and wait for the drivers to install. Fortunately, modern routers allow you to solve this problem by turning an ordinary wired device into a full-fledged network resource.

Usage USB to WiFi Using router-based technology eliminates the need to keep your computer turned on to access printing. You can print documents from any device in the house, be it a laptop, tablet, or even a smartphone, from anywhere in the apartment. In this article, we'll walk you through the setup process in detail, highlighting nuances often overlooked in standard instructions.

Before configuring the software, it's crucial to check the physical compatibility of your hardware. Not every router will work with every printer, even if the ports match. Printer compatibility with a router is checked only on the official website of the router manufacturer in the list of supported USB devices. If your model is not on the list, the chances of successful setup are extremely low and you will be wasting your time.

Checking compatibility and preparing equipment

The first step is to diagnose your hardware. You need to make sure that your router equipped with a USB port and supports the function Print ServerManufacturers often install ports only for external hard drives (NAS), and the printing function is blocked by software. Check the device's specifications or consult the technical documentation.

It's also worth preparing the printer itself. Make sure it's working properly, the cartridges are refilled, and the drivers are installed on the primary computer where you plan to begin setup. If the device has been used before, it's best to reset it to factory settings to avoid conflicts with old configurations. This usually requires holding down the Cancel button or the power button for 10-15 seconds.

⚠️ Attention: Don't connect the printer to the router until the network interface is fully configured. Turning on the power at the wrong time may cause the router to reboot or fail to detect the device correctly.

To connect, you'll need a high-quality USB cable. The cable shouldn't exceed 1.5-2 meters in length, as longer cables can result in signal loss and data transfer errors when connected to a router. Cheap, unshielded cables often cause unstable printing.

Setting up a USB port on the router

After the physical inspection, we move on to software configuration. Connect the printer to the switched-off router via USB, then power on the router and wait for it to fully boot up. Now you need to log in to the administrator's web interface. Open a browser and enter the router's IP address in the address bar, usually 192.168.0.1 or 192.168.1.1.

Enter your login and password to access the settings (by default it is often admin/admin). Interface from different manufacturers (TP-Link, Asus, Keenetic, MikroTik) is different, but the logic is the same. You need to find the section related to USB applications. It may be called USB Application, Print Server, Print server or be in the menu Additional settings → USB.

In the menu that opens, activate the function Print ServerThe system should detect the connected device. If your printer model is listed, the physical connection was successful. If the device is not detected, try reconnecting the cable or rebooting the router with the printer already connected.

Setting up the printing protocol is important. Most routers use a standard protocol. LPR or RAW. Make sure the correct port is selected, usually it is 9100Some advanced models allow you to create a separate account for the printer, which increases security, but for a home network, the default settings are sufficient.

Installing a network printer in Windows

Now that the router "sees" the printer, you need to teach the laptop's operating system to see it. In Windows 10 and 11, the process for adding a device has changed slightly compared to previous versions. Open the Start menu and go to Settings → Devices → Printers & Scanners. Click the button Add a printer or scanner.

The system will begin searching for available devices. If the automatic search yields no results (which often happens with network printers connected via a router's USB hub), click the link The printer you need is not listed.The installation wizard will open, where you need to select the item Add a printer by its TCP/IP address or hostname.

In the Name or IP Address field, enter your router's local IP address (e.g. 192.168.1.1). The system will generate a port name automatically. In the next step, Windows will attempt to detect the device type. If a window appears asking for additional port information, select it from the list. Custom and press Setting up. Make sure the protocol is selected. LPR, and the queue name is left blank or specified RAW.

⚠️ Attention: If Windows can't find the driver automatically, don't rely on the system database. Download the latest driver from the printer manufacturer's website and manually specify the path using the button. Install from disk.

After the driver is successfully installed, the system will prompt you to name the printer. Give it a descriptive name, such as "Office_USB_WiFi," to distinguish it from other devices on the network. Finally, the wizard will prompt you to print a test page. This is a mandatory step to verify that the data transfer is working correctly.

Setting up printing from mobile devices

One of the main advantages of this configuration is the ability to print from smartphones and tablets. For devices based on Android And iOS Standard Windows protocols may not work directly. This is where technology comes in. Google Cloud Print (although the service is closing, similar options remain) or native solutions from router manufacturers.

For iPhone and iPad users, the situation is easier thanks to technology AirPrintIf your router supports AirPrint forwarding for connected USB devices (this feature is available in Keenetic and some models Asus), then the iPhone will detect the printer automatically. Otherwise, you will need to install third-party intermediary apps, such as PrinterShare or PrintHand.

In the appendix PrintHand You need to select the "Wi-Fi" connection type and find your printer using the router's IP address. The app will automatically select the necessary driver from its extensive database. This is a paid solution, but it ensures stable operation where standard tools fail. For Android, using a plugin is also recommended. Mopria Print Service.

Solving typical problems and errors

Even if you follow the instructions correctly, problems may still occur. One of the most common issues is that the printer appears online, but its status is "Offline." This is often due to a change in the router's IP address if the network isn't configured with a static IP address. To avoid this, reserve an address for the printer's MAC address in the router's DHCP server settings.

Another common error is "Printing error" or stuck in queue. This can be caused by an incorrect port selection. In the printer properties (Ports tab), make sure the box next to the Standard TCP/IP port you created is checked, not WSD or DOT4Also try increasing the port timeout in its advanced settings.

If your router stops "seeing" your printer after a long period of inactivity, the problem may be with the USB port's power-saving settings. Some router models (for example, TP-Link) has a feature that turns off USB power when idle. This should be disabled to ensure the printer remains accessible to the network.

⚠️ Attention: Router firmware interfaces are regularly updated. Menu locations and item names may differ from those described. Always consult the official instructions for your specific firmware version.

Questions and Answers (FAQ)

Is it possible to connect a printer via a USB-WiFi adapter?

Regular USB WiFi adapters (dongles) designed for computers are not suitable for printers. Printers do not have an operating system to manage such adapters. There are special WiFi print servers — separate boxes into which the printer's USB cable is plugged, but it's cheaper and easier to use the built-in functionality of a modern router.

Why is my printer printing slowly over WiFi?

Network printing speed is limited by the bandwidth of the connection between the router and the printer, as well as the power of the router's processor, which processes the print queue. For text documents, the difference is imperceptible, but for photographs, there may be a 10-20 second delay before printing begins.

Will the scanner work via this connection?

In 95% of cases, no. The protocols used by routers for USB printers are designed only for printing (TCP/IP 9100, LPR protocols). Scanning functions require two-way communication and specific drivers, which the router cannot provide. You will have to scan via a cable or use network scanning functions, if the MFP itself has them.

Do I need to buy a router with USB 3.0 for my printer?

No, it's not necessary. The USB 2.0 interface, used in most printers, is significantly slower than even USB 1.1. A router with a USB 2.0 port is more than sufficient. USB 3.0 is only important for connecting external hard drives to set up a media server.
