how do i connect my hp laserjet pro m234dwe to wifi without using the app? my router has a wps button.

You can connect it directly using the WPS button on your router. Here's how.

1. Make sure your printer and router are close to each other.
2. On the printer control panel, press and hold the Wireless button for at least 3 seconds. The Wireless light will start blinking.
3. Within 2 minutes, press the WPS button on your router.
4. When connected, the printer's Wireless light will stop blinking and stay lit.
5. After that, you still need to add the printer to your device. Open the HP Smart app, tap the Plus icon or 'Add Printer', and follow the prompts to select and add your printer.
6. You'll be prompted to create an HP account and register the printer.

If that didn't work, the WPS handshake might have timed out. Start over, making sure to press the router's WPS button within the 2-minute window. If problems continue, using the HP Smart app for setup is the recommended alternative.
