Connecting a printer traditionally via USB cable often becomes a source of inconvenience, especially when you need to print a document from another computer or mobile device. Transforming a regular printer into a fully-fledged network device solves the problem of shared access and eliminates the clutter of cables. Modern technologies make this possible even for models that don't natively support wireless connectivity, leveraging the capabilities of your router or specialized minicomputers.
The setup process requires attention to detail, as every step affects the stability of the connection in the future. Network printer A printer isn't just a gadget on a local network, but a fully-fledged resource accessible to all authorized users. In this article, we'll explore proven connection methods that work with most modern routers and operating systems, ensuring reliable printing in the office or at home.
Before beginning software configuration, ensure the hardware is physically ready for use. Check that the printer itself is working properly, that drivers for your operating system are available, and that you have access to the router's admin panel. Wi-Fi router acts as a central hub that will route printing tasks from computers to the output device.
⚠️ Attention: Make sure your router supports USB Host. Not all router models can work with external devices connected via a USB port, even if one is physically present on the router.
Equipment preparation and compatibility testing
The first step is a detailed analysis of your router's capabilities. Many users mistakenly assume that the presence of a USB port automatically means the ability to connect a printer, but the ports' functionality may be limited to charging or using flash drives. You need to log into the router's web interface and check for tabs related to these features. USB Application, Print Server or Printer Settings.
If your router supports printing, the next step is to check the printer itself. Older models may require setting it to "Printer mode." local printing or disabling the "silent printing" feature, which sometimes blocks network requests. It's also critical to have up-to-date drivers on hand, as standard Windows tools may not recognize the device over the network without the correct software.
To connect, you'll need a high-quality USB Type AB cable (a standard printer cable). The cable should be no longer than 1.5–2 meters to avoid signal loss and unstable device operation. If the cable is too long or damaged, the router may simply not detect the device or experience constant interruptions.
Make sure the printer is turned on and ready before connecting to the router. Some models require a reboot after connecting to the router's USB port to properly initialize. Static IP address For a router in a local network, it is also desirable that the paths to the printer do not change after rebooting the equipment.
Setting up a print server on a router
The process of activating the printing function begins with logging into the router's control panel. Typically, this requires entering the address 192.168.0.1 or 192.168.1.1 in the browser's address bar. After logging in, find the section for USB devices. It may have different names in different manufacturers' interfaces (Asus, TP-Link, Keenetic, MikroTik), but the essence remains the same: activating the printing service.
Within the USB settings section, you need to select the operating mode of the connected device. Select the option Printer or Print ServerIf a choice of protocol is available, LPR or Raw (port 9100) are preferred, as they provide the fastest and most reliable data transfer without the unnecessary acknowledgements that are typical of the IPP protocol in some implementations.
Basic parameters for manual port configuration:Protocol: LPR or RAW
Port: 9100
Queue name: USB1 (or auto)
After enabling the print server function, the router may prompt you to download a special driver or configuration utility. This is often software from the router manufacturer that automatically configures the necessary paths in the system. However, manual configuration using standard Windows tools is considered more reliable and versatile.
⚠️ Attention: Router interfaces are frequently updated. Menu locations and item names may differ from those described. If you can't find the section you need, refer to the manual for your specific router model or check the "Advanced Settings" section.
Installing drivers and creating a TCP/IP port in Windows
On a Windows computer, the process is similar to adding a new local printer, but with a dedicated network port created. Open Control Panel, go to Devices and Printers, and select Add a Printer. When the system searches for printers, click the link "The printer I want isn't listed."
In the window that opens, select the "Add a printer by TCP/IP address or hostname" option. In the "Name or IP address" field, enter the local IP address of your router (e.g., 192.168.1.1). The system will attempt to detect the device; if detection fails, this is normal for some print server models, and you will need to continue the manual setup by unchecking the "Query printer" box.
The key point is creating a new port. In the device type, select Standard TCP/IP PortNext, the system will prompt you to configure additional port settings. Click "Settings" and ensure the protocol is selected. Raw and the port 9100This is the port that is typically used for direct printing.
- 🖨️ Select an existing driver from the list or click "Have Disk" if you have a driver file from the manufacturer.
- 📡 Make sure that SNMP support is enabled in the port properties if your printer can transmit status (toner level, paper presence).
- 💾 Save the settings and give the printer a descriptive name, such as "Office_WiFi_Printer," to distinguish it from local devices.
After the wizard completes installation, the system will prompt you to print a test page. This is a mandatory step to check the signal from the computer through the router to the printer. If the page prints, then TCP/IP port configured correctly and connection established.
☑️ Printer installation checklist
Connecting via Raspberry Pi for older models
If your router does not support the print server function or is unstable, the ideal solution is to use a single-board computer. Raspberry PiThis device turns any USB printer into a powerful network print server with support for modern protocols, such as AirPrint for Apple devices.
To implement this method, you'll need the Raspberry Pi board itself (any model from the Zero onwards will do), a power supply, a memory card with the operating system installed (usually Raspberry Pi OS), and a USB cable. Connect the printer to the Raspberry Pi's USB port and the board itself to the router via Ethernet or Wi-Fi. Next, install the package using the terminal. cups (Common Unix Printing System), which takes control of printing.
CUPS configuration is carried out via the web interface at the address localhost:631 or the Raspberry Pi's IP address. In the interface, you add the printer, select the driver (PPD file), and enable sharing. The advantage of this method is its flexibility: you can set up logging, user restrictions, and even send email notifications when printing is complete.
Why is Raspberry Pi better than a router?
Routers often have weak processors and limited RAM, which can cause complex documents (PDFs with graphics) to take a long time to print or even cause them to stop printing. The Raspberry Pi has sufficient computing power to quickly process any task without putting a strain on the main router.
Ensuring an uninterruptible power supply for the Raspberry Pi is crucial, as a sudden shutdown can corrupt the file system. It's also a good idea to assign a static IP address to the device in your router settings to ensure the printer's path remains constant. This transforms an old printer into a modern network device with minimal effort.
Organizing shared access via a computer
The least expensive, but limited, method is to use Windows' printer sharing feature. In this case, the computer to which the printer is physically connected via USB acts as a server. This method is suitable for small offices where the main computer is always on.
To configure the printer, go to "Settings" -> "Devices" -> "Printers & Scanners." Select the desired printer, click "Manage," and then go to "Printer Properties." On the "Sharing" tab, check "Share this printer" and set a network name. Now other network users can find it through Network Places.
However, this method has a significant drawback: the host computer must be constantly on and unlocked for printing from other devices. Furthermore, when printing large files, the host computer may temporarily experience a performance hit. This is acceptable for a home network of two or three devices, but for intensive office work, a router or Raspberry Pi is better.
- 🔒 The "Security" tab allows you to configure access rights, allowing printing only to certain users or groups.
- 🔄 When updating drivers on the host computer, client machines may need to reinstall the drivers.
- 📉 Print speed may be slower due to the host operating system's overhead in processing the queue.
⚠️ Attention: When using Windows sharing, ensure that device discovery and file and printer sharing are enabled in your network settings. Your firewall should also not block incoming connections for the print service.
Setting up mobile printing and AirPrint
Modern users often need to print directly from a smartphone or tablet. If you've used the Raspberry Pi method, AirPrint (for iOS) and Mopria (for Android) support is often built in automatically or requires minimal configuration in CUPS. For routers and Windows sharing, the situation is more complex.
For Android devices, the best solution is to install a proxy app, such as PrintHand or NokoPrintThese applications can find printers on the local network, even if they are connected via a router's USB port, and transfer documents, converting them on the fly into a printer-readable format.
iPhone and iPad users have better luck if their printer supports AirPrint natively or is emulated via a Raspberry Pi. Otherwise, third-party gateway programs on a PC can translate AirPrint requests into standard Windows print commands. This allows you to send documents from any Apple application to a regular USB printer.
| Connection method | Complexity | PC addiction | AirPrint support |
|---|---|---|---|
| USB port of the router | Low | No | Rarely |
| Raspberry Pi (CUPS) | Average | No | Yes (natively) |
| Windows Sharing | Low | Yes (PC must be turned on) | A gateway is required |
| Wi-Fi printer adapter | Average | No | Depends on the model |
When setting up mobile printing, it's critical that the smartphone and printer (or print server) are on the same subnet. If you have a guest Wi-Fi network configured, devices on the guest network are often isolated from the main network and won't be able to see the printer. In such cases, you'll need to either disable client isolation or connect the phone to the main network.
Troubleshooting and Common Mistakes
During setup, users often encounter a situation where the printer appears on the network, but the status is "Disconnected" or "Printing Error." First, check the physical connection: try reconnecting the USB cable to a different router port. Some ports may not provide enough current to operate the printer, especially if it's power-hungry.
A common problem is driver conflicts. Windows may automatically install a generic driver that doesn't work correctly over the network. Remove the device completely and install the driver strictly from the manufacturer, selecting the connection type "Network" or "TCP/IP" during installation.This ensures that the correct ports and communication protocols are used.
If printing is successful, but very slow, or drops out on large documents, try changing the port settings. In the TCP/IP port properties, disable SNMP support if it's enabled, or experiment with switching between LPR and Raw protocols. Also, check if your router has speed limiting (QoS) for USB devices.
If your printer suddenly stops responding, resetting the print queue can help. Open Windows Services (command services.msc), find the Print Spooler service and restart it. This clears temporary files and resets frozen tasks, often restoring the device to working order without restarting the computer.
Why doesn't the router see the printer via USB?
There could be several reasons: the printer requires specific initialization that the router can't handle; the printer's file system is incompatible; or the router port is damaged. Try updating the router's firmware or checking the list of compatible devices on the manufacturer's website.
Is it possible to connect a printer via a Wi-Fi adapter (whistle)?
Only if the printer itself supports external Wi-Fi modules (usually proprietary adapters from the printer manufacturer). Regular USB Wi-Fi adapters for PCs plugged into the printer won't work, as the printer doesn't have drivers to manage the network interface.
Is it safe to leave a printer on a shared network?
Yes, if your local network is protected with a strong password. However, older printers may have firmware vulnerabilities. It is recommended not to expose port 9100 directly to the internet via router settings (Port Forwarding), limiting access only to those within your home network.
How to change the IP address of a network printer?
If the printer is connected via a router, its address is the router's IP address. If you're using a print server or Raspberry Pi, the IP address is changed in the device's static IP settings or in the router's DHCP reservation settings.
