Few things are more frustrating than hitting Print for an urgent document, only to find your printer isn’t working normally. If your HP LaserJet Pro M402n shows up as “Offline,” refuses to print, or prints garbled text, the very first thing is to check its driver.
Think of a driver as the official translator between Windows and your printer. Keeping it updated helps prevent print queue hangups and keeps your hardware running smoothly. Below, we’ll walk through three practical ways to get your HP M402n driver updated without any hassle.

Method 1: Download HP LaserJet Pro M402n driver manually
The HP manufacturer provides the driver software for their printers, so you can manually download the printer driver you need from the HP support website.
1) Simply go to the HP software and drivers download page and select Printer. 
2) Search for your printer model: Color LaserJet Pro M452dn, and select the correct one from the results.
3) Check if your Windows version is detected correctly. If not, click Choose a different OS and select your Windows version.
4) Scroll down and download the recommended driver or printer software package.
5) Once you’ve downloaded the correct driver for your system, double-click the downloaded file and follow the wizard to install the driver.
If you’re connecting via network and the HP installer fails to auto-detect your printer, temporarily disable third-party firewall software or enter the printer’s IP address manually.
If this method doesn’t work for you, don’t worry. Move on to the next method.

Bonus troubleshooting tips
The driver is installed, but the printer is still offline?
Even with the correct driver installed, Windows sometimes gets confused by network ports. If your HP LaserJet M402n keeps switching to “Offline” or fails to print, the most effective fix is switching from a volatile WSD Port to a stable Standard TCP/IP Port. Here’s how:
1) Press the Windows key + I to open Settings.
2) Go to Bluetooth & devices > Printers & scanners.
2) Select your HP LaserJet Pro M402n. Then click Printer properties.
3) Go to the Ports tab and check which port is selected. If it shows a WSD port, click Add Port….
4) Select Standard TCP/IP Port and click New Port.
5) Enter your printer’s static IP address (e.g., 192.168.1.150), click Next, and complete the wizard.
To find your printer’s IP address: 1) Open the menu on your HP LaserJetM402n printer; 2) Scroll to Reports and press OK; 3) Select Network Summary or Network Configuration Page and press OK; 4) The printer will print out a physical configuration report page. Grab that sheet, look for the IPv4 Address section (it usually looks like 192.168.1.X or 10.0.0.X).
6) Uncheck the old WSD port, ensure your new TCP/IP port is checked, and click Apply.
