While the basic configuration doesn't include a wireless module, the system allows for easy integration. Proper setup will allow you to eliminate unnecessary cables and print documents directly from your smartphone or tablet.

In this guide, we'll cover the process of activating wireless connectivity, selecting compatible hardware, and fine-tuning settings across various operating systems. You'll learn how to avoid common mistakes and ensure a stable connection for fast printing at all times.

Checking compatibility and choosing a Wi-Fi adapter

Before you begin setting up your printer, you need to make sure you have a key component—the wireless module. HP LaserJet Pro M104a It doesn't have built-in Wi-Fi, so you'll need to purchase a dedicated USB adapter to set up a wireless network. Without this adapter, any attempts to set up a network will fail.

It is critically important to understand that not every USB dongle will work with this printer. The company HP Certified only certain adapter models that are guaranteed to work with the device's firmware. Using third-party alternatives may result in unstable operation or complete rejection of the module by the printer.

⚠️ Attention: The officially supported adapter for the M104 series is the model HP Jetdirect 1700n or specific modules of the series N300Before purchasing, be sure to check the part number against the compatibility list on the manufacturer's official website, as component availability may vary.

The adapter installation process is physically simple, but requires following a specific sequence of steps. Insert the module into the USB port on the front or rear panel of the device (depending on the specific revision). The printer should automatically detect the new hardware.

List of compatible adapters

HP officially recommends using the adapters included with 'w' series models (e.g., M104w) or purchasing genuine HP modules. Using cheap Chinese alternatives from AliExpress in 90% of cases results in the inability to activate wireless mode.

Preparing the network and resetting the printer

A successful connection depends not only on the hardware but also on the network settings of the device itself. If the printer was previously used on a different network or the settings were reset, an IP address conflict may occur. It is recommended to reset the network settings before starting a new configuration.

To do this, press the wireless button on the control panel (if enabled by the adapter) or use a key combination. Often, you'll need to hold down the Wi-Fi and Cancel buttons simultaneously for a few seconds. The lights will begin flashing, indicating the reset.

  • 📡 Make sure your router is distributing the network in the range 2.4 GHz, as many HP printers do not support 5 GHz.
  • 🔒 Check the encryption type: the device works most reliably with WPA2-Personal.
  • 📶 The Wi-Fi signal at the printer installation location must be strong, without strong interference from microwave ovens or powerful electrical appliances.

It's also important to know your Wi-Fi network password in advance. Entering data through the control panel can be difficult due to the lack of a full screen, so it's best to prepare all data for entry on a computer or mobile app.
