The Quick Answer
Set up HP DeskJet 3755 Wi-Fi without the HP Smart app: the WPS method and the printer's own hidden web page, explained by a repair tech.
Not everyone wants another app on their phone just to print a document. If you'd rather set up your HP DeskJet 3755's Wi-Fi without the HP Smart app, you have two genuinely solid options — and one of them is a small built-in web page most owners never realize the printer has, tucked away in its own temporary network.
Here's both methods, plus the fallback if neither one works cleanly.
Quick-Fix Summary
Fast version:
- WPS button method — fastest, if your router supports it.
- The printer's own web interface — my uncommon tip, and the real no-app solution.
- USB cable with driver-only install — works, but requires physical setup first.
- Check for a WPS button on your specific router before assuming you don't have one.
Method 1: The WPS Button
If your router has a WPS button (often labeled "WPS" directly, sometimes with a looping arrow icon, usually on the back or side of the router):
- On the printer, press and hold the Wireless button for at least 3 seconds, until the wireless light starts blinking.
- Within 2 minutes, press the WPS button on your router.
- The printer should connect automatically, and the wireless light will turn solid once it succeeds.
Why this works: WPS (Wi-Fi Protected Setup) is a standard built directly into both the printer and most modern routers, designed specifically to let two devices establish a secure connection without typing a password anywhere or installing any software at all. It's the closest thing to a true no-app, no-typing setup method that exists.
Method 2: The Printer's Own Hidden Web Page (My Uncommon Tip)
Here's the method almost nobody knows exists, because it doesn't come up in the printer's quick-start guide at all — the guide just tells you to download the app. But the DeskJet 3755 actually hosts its own tiny built-in web configuration page, and you can reach it directly from any browser with zero software installed.
- On your phone or computer's Wi-Fi settings, look for a temporary network broadcast by the printer itself — this typically appears when the printer is freshly powered on and not yet connected to any network, often named something like "HP-Setup" or similar. Connect to it.
- Open any web browser and type the printer's default setup address directly into the address bar: http://192.168.223.1
- This opens the printer's built-in web interface. Click the Network tab, then the Wireless sub-tab.
- Click Wireless Setup Wizard. The printer will scan for and list nearby Wi-Fi networks.
- Select your network from the list, enter your Wi-Fi password when prompted, and click Connect.
Why this works: every network-capable HP printer runs a small internal web server for configuration purposes, normally reached through its assigned IP address once it's already on your network — but before it's connected to anything, it briefly hosts its own standalone network specifically so you can reach that same web interface directly, no app or driver required. This is functionally identical to what the HP Smart app does behind the scenes when it walks you through wireless setup — the app is really just a friendlier front end for this same built-in page. Once you know this page exists, you've bypassed the entire reason most people feel pushed toward installing an app they didn't want.
Method 3: USB Cable With Driver-Only Install
If you have a USB cable available: connect the printer directly to your computer, download just the driver package (not the full HP Smart app) from HP's support site for your exact model, and run the installer. Most driver-only installers will walk you through wireless setup as part of the installation, without ever installing the separate app.
Why this works: the printer driver and the HP Smart app are two separate pieces of software, and installing the driver alone is sufficient to print — the app adds convenience features like ink level monitoring and scanning shortcuts, but it isn't required for the printer to function. This method requires a brief physical cable connection to complete setup, but afterward the printer operates wirelessly with no ongoing need for a cable or the app.
A Note on "My Router Doesn't Have a WPS Button"
Many newer routers, especially ones from internet providers, either hide WPS in their own app or have disabled it entirely for security reasons — WPS has some known vulnerabilities, so some providers turn it off by default even when the hardware technically supports it. If you don't see a physical WPS button, check your router's own app or web interface for a WPS toggle before concluding it's unavailable. If it's genuinely absent, Method 2 (the printer's own web page) becomes your best no-app option, since it doesn't depend on your router supporting anything special at all.
When to Call a Professional
If neither the WPS method nor the printer's own web interface can complete a wireless connection — the printer's temporary setup network never appears, or the Wireless Setup Wizard can't detect your home network at all — try moving the printer closer to the router temporarily to rule out a weak signal, and confirm your network is broadcasting on 2.4GHz, since this model doesn't support 5GHz. If both checks come back clean and setup still fails, contact HP support with your printer's serial number; a genuine Wi-Fi radio fault in the unit becomes the more likely explanation, and it's worth checking current warranty status before pursuing paid repair.
FAQ
Can I really set up the HP DeskJet 3755 without installing any app?
Yes — either the WPS button method or the printer's own built-in web interface (reached at http://192.168.223.1 while connected to its temporary setup network) completes wireless setup with zero software installation.
What's the printer's temporary setup network called?
It typically appears as something like "HP-Setup" followed by characters specific to your printer, visible in your device's Wi-Fi network list only while the printer is unconfigured and powered on.
Does the DeskJet 3755 support 5GHz Wi-Fi?
No — this model only supports 2.4GHz networks. If your router broadcasts both bands under the same name, you may need to temporarily separate them or ensure your device connects to the 2.4GHz option during setup.
Do I need the HP Smart app for anything after wireless setup is complete?
No, not strictly. Once connected wirelessly, you can print through any application's normal print function. The app adds convenience features like ink monitoring and mobile scanning, but ongoing printing doesn't require it.
Setting up HP DeskJet 3755 Wi-Fi without an app comes down to two solid paths: the WPS button for speed, or the printer's own hidden web interface at 192.168.223.1 for a genuinely software-free setup. Both get you fully connected in a few minutes, no download required — you just have to know they're there.
