The situation where a modern laptop or smartphone can't communicate with a reliable, but "ancient" inkjet or laser printer without wireless networking is familiar to many. This often happens in offices or apartments where Ethernet cables are already installed, but running a USB cable to the computer is inconvenient or simply impossible. In such situations, a logical question arises: is it possible to somehow upgrade the equipment to eliminate these unnecessary cables?
Fortunately, technological advancements offer several proven solutions that allow integrate Integrate old equipment into a modern infrastructure. You don't necessarily need to buy a new MFP if your current one prints properly but lacks a communication module. There are three main solutions: using an external USB-Wi-Fi adapter, setting up print servers Using a router or creating a software access point via a connected computer. The choice of a specific method depends on your router model, the availability of available USB ports, and the user's willingness to tinker with network settings.
Before we get started, it's important to understand that simply plugging a USB dongle into the printer's port will only work in the rarest of cases. Most office models don't have built-in drivers for working with custom wireless modules. Therefore, we'll be looking at methods that will actually work in 2026-2026, turning a local device into a network resource.
Hardware Solutions: USB Wi-Fi Adapters and Print Servers
The simplest solution would seem to be to buy a special USB adapter, plug it into the printer port, and enjoy wireless printing. However, there's a major pitfall: driver compatibility. Print server It must be able to communicate with the specific adapter chipset. Printer operating systems are extremely limited and rarely include drivers for popular devices like TP-Link or D-Link.
If your device is a budget or mid-range office model, the chances of it recognizing a random Wi-Fi module are slim to none. Printer manufacturers often block the use of third-party modules, forcing you to buy their proprietary, often discontinued, accessories. In such cases, external hardware print servers—small boxes with a USB port and antenna—come to the rescue.
These devices operate independently of the computer and printer itself, taking over the task of data routing. You connect the printer to this server via a USB cable, and the server then transmits data over the air to the network. This turns any USB model into a fully-fledged network resource, accessible to all users on the local network.
- 📡 Compatibility: External servers support a wide range of models as they emulate a standard USB port.
- 🔌 Autonomy: The computer can be turned off, but printing will still work over the network.
- 💰 Price: A dedicated print server can cost almost as much as a new Wi-Fi printer.
⚠️ Important: Before purchasing an external print server, be sure to check the list of supported devices on the manufacturer's website. Support for PCL and PostScript print languages on the server is critical for proper operation.
Why don't all adapters work?
The microprocessors built into printers have very little memory and cannot load the complex drivers of modern Wi-Fi adapters. They only work with specific chipsets, which the manufacturer pre-programs into the firmware.
Setting up a router as a centralized printing node
A smarter and more cost-effective solution is often to use the capabilities of your routerMany modern routers, especially models from Keenetic, ASUS, TP-Link, and MikroTik, have a USB port and a built-in Print Server feature. This allows you to connect a printer directly to the router and share it with all devices on the network.
The setup process typically doesn't require extensive programming knowledge, but it does require attention to detail. You'll need to connect the device to the router via a USB cable, log in to the administrator's web interface (usually at 192.168.0.1 or 192.168.1.1), and find the section responsible for USB applications or printers. Here, the system will prompt you to enable the printing service and possibly install additional components.
It's important to note that not all routers can handle complex print commands. Simple text documents may print without issue, but heavy graphics or PDF files may get stuck in the print queue. This is due to the limited processing power of the router's processor, which is also busy distributing the internet.
- Connect the printer to the router's USB port and wait for the system to boot up.
- Access your router settings through your browser using
adminrights. - Find the section
USB ApplicationorPrint Serverand activate it. - Copy the IP address assigned to the printer by your router or use the hostname.
After activating the service on the router, you need to add a new printer to your computers. Unlike a regular connection, here we don't select a USB port, but create a new one. TCP/IP portIn the address field, enter the IP address of the router or the printer itself, if obtained via DHCP. The system will automatically detect the device if the protocols are compatible.
Software methods: sharing via Windows
If your router doesn't have a USB port and you don't want to buy additional hardware, you can turn one of your network computers into a server. This method is called software sharing (sharing). The computer to which the printer is connected must be constantly turned on and online so that other users can print the document.
To implement this method in Windows, go to the device settings. Under "Devices and Printers," select the desired MFP, right-click, and select "Printer properties." Go to the "Sharing" tab and check the "Share this printer" box.
Next, it's important to configure security settings correctly. Older versions of Windows (such as 7 or XP) often required disabling password protection, which is a security hole. In modern systems (Windows 10/11), it's best to create a separate user with only printing permissions to avoid compromising the entire computer.
| Parameter | Default value | Recommended value |
|---|---|---|
| Resource name | PrinterName | Office_Laser_Black |
| Access | Disabled | On |
| Print queue | Priority 50 | Priority 100 (for server) |
| Drivers | Current OS only | Additional drivers (x64/x86) |
After setting up the printer on the host computer, on client devices (laptops, tablets), select "Add Printer" -> "The printer I want isn't listed." Select the "Select a printer by name" option and enter the path in the following format: \\ComputerName\PrinterNameIf the network is configured correctly, the system will automatically download the drivers.
Using a Raspberry Pi to Build a Wi-Fi Printer
For enthusiasts and those who value perfect stability, the best solution would be to create a dedicated print server based on a single-board computer. Raspberry PiThis miniature device consumes minimal power, operates silently, and can be left next to a printer for years. The Raspberry Pi runs CUPS (Common Unix Printing System).
CUPS is the gold standard for print management in Linux, supporting thousands of printer models. Installation takes just a few minutes via the terminal. Once installed, CUPS allows you to manage your print queue via a convenient web interface, accessible from any device on the network at http://localhost:631.
The main advantage of this method is protocol support AirPrintThis means iPhone and iPad owners can print directly, without installing drivers, simply by selecting the printer in the iOS menu. The IPP Everywhere protocol is also supported, making the device visible to Android and Windows 10/11 without any configuration.
- 🍓 Flexibility: You can set up printing logic, email notifications when a job is completed or when there is no paper.
- 🛡️ Safety: Isolated system, not susceptible to Windows viruses.
- ⚡ Speed: Instant printing starts because the server is not sleeping or in power saving mode.
⚠️ Note: Using Raspberry Pi requires a basic understanding of the Linux command line. If you've never used the terminal before, this method may seem complicated.
The setup process involves installing the OS (for example, Raspberry Pi OS Lite), connecting the board to the network (via Wi-Fi or cable), installing packages cups And cups-browsed, and then adding the user to the group lpadminAfter this, the printer is added in the web interface, and it becomes available to the entire network.
Compatibility and driver issues
When trying to make a printer wireless, the "digital Babel" problem often arises, with devices speaking different languages. Older printers may use outdated page description languages, such as PCL5 or older versions of PostScript, which modern mobile devices don't understand out of the box.
This is especially true when connecting via routers or Raspberry Pi. If you send a document from your phone, it often sends the data in PDF or image format. If the printer is "stupid" and can't interpret PDF files on its own, the print server must render the page into a raster (bitmap) before sending it. This process is called rasterization.
Rasterization is handled by the server (router or Raspberry Pi). If the server is underpowered, printing the first page can take several minutes. In some cases, manual download and installation is required. PPD files (PostScript Printer Description) for a specific model so that the server knows exactly how to control that device.
sudo apt-get install printer-driver-foo2zjs
sudo apt-get install printer-driver-gutenprint
The commands above show an example of installing additional driver packages in a Linux environment to support specific models. In Windows, the equivalent is manually selecting a driver from the "Have Disk" list when adding a network printer.
Optimizing network speed and security
Once successfully connected, it's important to ensure that printing doesn't slow down your internet connection or create security holes. A network printer, especially one with public access, can become an entry point for attackers if the ports aren't closed. The standard printing port is 9100 (JetDirect), ports are also used 631 (IPP) and 515 (LPR).
It's recommended to create a separate guest Wi-Fi network for the printer if your router supports VLANs or guest isolators. However, guest networks are often isolated from the main network, preventing computers from seeing the printer. Therefore, it's best to use the main network, but with a strong encryption password. WPA2/WPA3.
To speed up performance, ensure the print server and client devices are in the same frequency band. If your router is dual-band, it's best to use 5 GHz for transferring large files, although 2.4 GHz is sufficient for text. It's also a good idea to reserve the printer's IP address in your router's DHCP settings to prevent it from changing.
- 🔒 Ports: Close access to the printer management port (usually 80 or 443) from the external network (WAN).
- 📶 Signal: Make sure that the Wi-Fi signal level at the location where the printer is installed is at least -70 dBm.
- 🔄 Protocols: Disable the legacy SMBv1 protocol on computers if you use Windows sharing.
⚠️ Please note: Router interfaces and firmware versions are constantly being updated. Menu locations and function names may differ from those described in the instructions. Always consult the official manual for your router model.
Implementing wireless printing on a device without Wi-Fi is a great way to extend the life of your equipment and improve user experience. Whether it's a simple USB dongle, a router setup, or a powerful Raspberry Pi server, there's a solution to suit your budget and skill level. The key is to choose the right method that doesn't require you to be constantly at your computer.
Is it possible to connect a printer to Wi-Fi directly via a USB cable?
No, a standard USB cable (like the USB Type-B cable used to connect a printer to a PC) cannot transmit a Wi-Fi signal. USB is a wired interface. Wireless communication requires an intermediate element: an adapter, router, or computer that converts the signal.
Why doesn't the printer print even though it's visible on the network?
Most often, the problem is with the driver. When connecting to a network, Windows may automatically install a generic driver that doesn't support all the device's features. Try uninstalling the printer, downloading the full driver package from the manufacturer's website, and selecting "Network Connection" during installation.
Does AirPrint work through a router for an old printer?
A router itself rarely supports AirPrint out of the box. This requires an intermediary program (for example, on a Raspberry Pi or a Windows PC running a special service) that will emulate the Apple protocol for the older device.
Do I need a static IP for a network printer?
Recommended. If the printer's IP address changes after rebooting the router, computers will lose connection to it, and you'll have to re-add the print port. Reserving the address in the router's DHCP server will solve this problem.
