How to connect your HP Deskjet 3755 to WiFi
The HP Deskjet 3755 connects to WiFi through the printer's built-in menu system, and the process takes about five minutes. You'll need your WiFi network name and password, and the printer must be turned on and within range of your router. The printer will search for available networks, you'll select yours, enter the password, and the connection completes automatically — no computer required for this step.
Once connected, your printer stays on the network and prints from any device in your home without needing to plug in a USB cable each time. If the connection fails, the printer will tell you why on its small screen, and most problems solve by restarting the printer or double-checking your password.
Key Takeaways
- The HP Deskjet 3755 has a WiFi button on the printer itself that starts the connection process without needing a computer.
- You must know your WiFi network name and password before you begin, because the printer will ask for both.
- The printer's small screen will display error messages if something goes wrong, telling you whether the problem is the password, the network, or the printer's distance from the router.
- After the first connection, the printer remembers your network and reconnects automatically when you turn it on.
Locate the WiFi button and turn on the printer
The WiFi button is on the front of the HP Deskjet 3755, just below the screen. It looks like a small icon with curved lines radiating outward — the standard WiFi symbol. Press and hold this button for about three seconds until the screen lights up and shows a message about WiFi setup. The printer will beep once to confirm it is listening.
Make sure the printer is plugged in and has paper in the tray. The printer needs power to search for networks, and it will not complete the connection if it runs out of paper during the process. If the printer is already on, you can press the WiFi button directly without turning it off first.
Select your WiFi network from the printer's screen
After you press the WiFi button, the printer's screen will show a list of available networks within range. This list appears within 10 to 15 seconds. Scroll through the list using the arrow buttons on the printer's control panel — usually the up and down arrows on the right side of the screen. Look for your network name, which is the same name you see when you connect a phone or laptop to WiFi.
Once you find your network, press the OK button or the button marked with a checkmark to select it. The printer will then ask you to enter your WiFi password. Do not worry if your network does not appear — this usually means the printer is too far from the router, or the router is turned off. Move the printer closer to the router and try again.
Enter your WiFi password using the printer's keypad
The printer will display a keyboard on its screen after you select your network. Use the arrow buttons to move between letters, numbers, and symbols. Press OK or the checkmark button to select each character. This process is slow, so take your time and double-check each letter as you enter it — passwords are case-sensitive, meaning capital letters and lowercase letters are different.
If you make a mistake, look for a backspace or delete button on the screen, usually marked with an arrow pointing left. After you finish typing the password, press the button marked "Done" or "Connect" to send the password to the printer. The printer will take 10 to 20 seconds to verify the password and connect to your network.
Confirm the connection is successful
When the connection succeeds, the printer's screen will show a message saying "Connected" or "WiFi Connected," and a WiFi icon will appear in the top corner of the screen. This icon looks like the same curved lines you see on your phone when it is connected to WiFi. The printer will also print a small confirmation page automatically, which you can keep or discard.
If the connection fails, the screen will show an error message. The most common message is "Incorrect Password" — this means you typed the password wrong. Go back to the WiFi button, select your network again, and re-enter the password more carefully. If the message says "Network Not Found," the router may be off, or the printer may be out of range. Move the printer closer to the router and try again.
Test the connection by printing from your computer or phone
Once the printer shows "Connected," open any document on your computer or phone and send it to print. On Windows, go to File, then Print, and look for "HP Deskjet 3755" in the list of printers. On a Mac, go to File, then Print, and select "HP Deskjet 3755" from the dropdown menu. On a phone, use the share button in most apps and look for a print option.
If the printer does not appear in the list, restart your computer or phone and try again. Sometimes devices need a few seconds to discover the printer on the network. If it still does not appear after a restart, go back to the printer and confirm the WiFi icon is still showing in the top corner of the screen. If the icon is gone, the connection dropped and you will need to reconnect using the WiFi button again.
Reconnect if the printer loses WiFi
If the printer loses its connection to WiFi — because the router restarted, the printer was moved, or the network changed — the WiFi icon will disappear from the screen. To reconnect, press the WiFi button again and follow the same steps: select your network, enter your password, and wait for the confirmation message. The printer remembers your network name and password, so you will not need to type the password again if you are reconnecting to the same network.
If you change your WiFi password, you will need to enter the new password the next time you press the WiFi button. The printer cannot use the old password, so it will show an "Incorrect Password" error until you provide the new one. If you move the printer to a different location and cannot find your network in the list, the printer may be too far from the router — move it closer and try again.
Frequently Asked Questions
Can I connect the HP Deskjet 3755 to WiFi without a computer?
Yes. The WiFi button on the printer itself handles the entire connection process. You do not need a computer, phone, or any other device to connect the printer to your network — only your WiFi password. After the printer is connected, you can then print from your computer or phone, but the connection itself happens on the printer alone.
What if I forgot my WiFi password?
You will need to find your password before you can connect the printer. On Windows, go to Settings, then Network, then WiFi, then Manage Known Networks, select your network, and click Properties — the password appears under Security. On a Mac, open Keychain Access, search for your network name, and check the box that says "Show Password." If you cannot find it, restart your router, which may reset the password to the default printed on the router's label.
Why does the printer keep disconnecting from WiFi?
The most common cause is that the printer is too far from the router or there is a wall or metal object between them. Move the printer closer to the router and away from microwaves, cordless phones, and baby monitors, which can interfere with WiFi. If the problem continues, restart both the printer and the router by turning them off for 30 seconds, then turning them back on.
Do I need to use a USB cable after connecting to WiFi?
No. Once the printer is connected to WiFi, you can print from any device on your network without plugging in a cable. The USB cable is only needed if you want to connect the printer directly to a single computer, or if you cannot get WiFi to work. Most people unplug the USB cable after the WiFi connection is confirmed.
Can multiple devices print to the same printer over WiFi?
Yes. Once the printer is connected to your WiFi network, any computer, phone, or tablet on the same network can print to it. You do not need to set up the connection separately for each device — they all find the printer automatically once it is on the network and powered on.
