The fastest way: using the printer's built-in setup button
The HP Deskjet 2755e has a WiFi Direct button on the front panel — a small circular button with a WiFi symbol. Press and hold it for three seconds until the WiFi light blinks. This puts the printer into pairing mode for about two minutes.
On your phone or computer, open your WiFi settings and look for a network name starting with "DIRECT-" followed by numbers. Select it and enter the PIN shown on the printer's screen (usually printed on a label on the back or inside the access panel). Once connected, the printer remembers your network and connects automatically when you turn it on.
This method works even if you do not know your WiFi password, because the printer and device pair directly. After pairing, you can print from that device without needing the printer on your main home network.
Key Takeaways
- The WiFi Direct button on the front of the printer lets you connect without knowing your WiFi password.
- Your home WiFi network requires the printer to be within range and you to enter your WiFi password once during setup.
- The HP Smart app on your phone or computer can walk you through the connection step by step and store the printer for future use.
- If the printer will not connect, restart both the printer and your router, then try again.
- Once connected, the printer stays on your network until you manually remove it or factory reset the printer.
Connecting to your home WiFi network instead
If you want the printer on your main home network so all devices can find it, press the WiFi button once (not held). The WiFi light will blink slowly. On your phone or computer, go to WiFi settings and select your home network name, then enter your WiFi password.
The printer will attempt to join. If it succeeds, the WiFi light stops blinking and stays solid. If it fails, the light blinks rapidly or turns off. Check that you entered the password correctly — the printer is case-sensitive and will not connect if even one character is wrong.
Once on your home network, you can print from any device on that same network without pairing each one individually. This is the setup most people use for a household printer.
Using the HP Smart app to set up WiFi
read the HP Smart app (free, available for iPhone, Android, Windows, and Mac). Open it and tap "Add a printer." The app will search for nearby HP printers and show your Deskjet 2755e in the list.
Tap your printer name. The app will ask whether you want to connect via WiFi Direct or your home network. If you choose home network, it will prompt you to enter your WiFi password. The app sends the password to the printer automatically — you do not type it on the printer itself.
The HP Smart app also handles driver installation on Windows and Mac, so you do not need to visit HP's website separately. After setup, the app stores your printer and can print documents, photos, and web pages directly from your phone or computer.
What to do if the printer will not connect
Restart the printer first: turn it off, wait 10 seconds, and turn it back on. Then restart your router (unplug it for 10 seconds, plug it back in). Wait for the router to fully boot — the lights should stabilize — before trying to connect the printer again.
If the printer still will not connect, check that it is within range of your router. The Deskjet 2755e has a range of about 100 feet in open space, but walls and metal objects reduce that. Move the printer closer to the router and try again.
If you are using a 5 GHz WiFi network, the printer may not support it — the Deskjet 2755e works only on 2.4 GHz networks. Check your router settings to see which band you are broadcasting on. If your router broadcasts both, look for a separate 2.4 GHz network name and connect to that instead.
Removing the printer from WiFi or resetting it
To disconnect the printer from your home network without resetting everything, go to the printer's settings menu (usually accessed through the control panel or the HP Smart app). Look for "Network Settings" or "WiFi Settings" and select "Forget Network" or "Remove Network." The printer will disconnect but keep all other settings.
If you want to completely reset the printer to factory settings — erasing all network information and restoring defaults — hold down the power button for 10 seconds while the printer is off. Some models require holding a combination of buttons; check your printer's manual for the exact sequence. After a factory reset, you will need to set up WiFi again from the beginning.
Printing after the printer is connected
Once the printer is on your home network or paired via WiFi Direct, printing is straightforward. On Windows, go to Settings > Devices > Printers & Scanners, find your Deskjet 2755e, and set it as the default printer. On Mac, go to System Preferences > Printers & Scanners, click the plus button, and select your printer from the list.
From any app, open the print dialog (usually File > Print or Ctrl+P on Windows, Command+P on Mac). Your Deskjet 2755e should appear in the printer list. Select it and click Print. The first time you print to a new printer, your computer may read drivers automatically — this can take a minute or two.
If the printer does not appear in the list, make sure it is turned on and connected to WiFi (the WiFi light should be solid, not blinking). Restart the app you are trying to print from, or restart your computer, and try again.
Frequently Asked Questions
Can I use the printer on both WiFi Direct and my home network at the same time?
No. The printer can be on one network or the other, not both. If you are connected to WiFi Direct, you must disconnect and rejoin your home network to print from other devices. Most people use home network mode for everyday printing and WiFi Direct only when they need to print from a single device without the main network.
What is the difference between WiFi Direct and connecting to my home network?
WiFi Direct creates a direct connection between the printer and one device — useful if your WiFi is down or you want to print without your main network. Home network connection puts the printer on your regular WiFi, so all devices on that network can find and print to it. Home network is the standard setup for a household printer.
Do I need the HP Smart app to connect the printer to WiFi?
No. You can connect using the WiFi button on the printer and your device's WiFi settings alone. The app is optional but helpful because it walks you through setup, stores your printer for quick access, and handles driver installation automatically.
Why does the printer keep disconnecting from WiFi?
The most common cause is that the printer is too far from the router or blocked by walls. Move it closer and try again. If it still disconnects, restart both the printer and router. If disconnections continue, your router may be dropping the 2.4 GHz band — check your router settings to confirm it is broadcasting on 2.4 GHz.
Can I connect the printer to a guest WiFi network?
Yes, if your router has a guest network. The printer connects to it the same way as your main network — enter the guest network name and password when prompted. Keep in mind that devices on the guest network may not be able to print to the printer if your router isolates guest devices from the main network.
