The printer uses a two-cartridge system with separate black and color cartridges. The black cartridge produces up to 190 pages per cartridge, while the color cartridge yields approximately 165 pages. Print speeds reach up to 7.5 pages per minute for black and white documents and 5.5 pages per minute for color documents. The maximum print resolution is 1200 x 1200 dots per inch, which produces reasonably sharp text and images suitable for everyday documents, photos, and creative projects.

Input capacity includes a 60-sheet paper tray for standard letter-size documents. The automatic document feeder on the scanner bed holds up to 25 sheets, allowing users to scan or copy multiple pages without manually feeding each sheet. The printer connects to computers and mobile devices through USB connection or WiFi wireless networking, providing flexibility in how you use the device from different rooms or locations in your home.

The printer operates on a standard 120-volt electrical outlet and includes basic control buttons on the front panel plus a small display screen. Power consumption during printing averages around 15 watts, while in sleep mode it uses minimal electricity, making it relatively efficient for regular household use.

Practical Takeaway: Before beginning WiFi setup, familiarize yourself with the physical layout of your printer, including the location of the power button, USB port, and WiFi indicator light. This knowledge helps you troubleshoot connection issues more effectively if problems occur.

Preparing Your WiFi Network and Environment for Printer Connection

Successfully connecting your HP DeskJet 3755 to WiFi begins with ensuring your wireless network meets basic requirements. Your router should operate on either 2.4GHz or 5GHz frequency bands, as the HP DeskJet 3755 is compatible with both standards. Most modern home routers broadcast on 2.4GHz by default, which typically provides better range and wall-penetration than 5GHz, though 5GHz offers potentially faster speeds for devices located near the router.

Your WiFi network should use WiFi Protected Access (WPA) or WPA2 security encryption, which are current standard security protocols. Networks using the older WEP encryption may not work reliably with this printer model. Write down your network name (SSID) and password before beginning the setup process. These credentials are typically printed on a sticker attached to your router, or you can find them in your router's settings menu accessed through a computer or mobile device.

Physical placement of your printer matters significantly for reliable WiFi connectivity. Position the printer within 30 feet of your router for optimal signal strength. Avoid placing the printer in enclosed spaces like cabinets or closets, as walls and metal objects can weaken wireless signals. Keep the printer away from microwave ovens and cordless phones, as these devices operate on similar frequencies and can cause interference. A clear line-of-sight path between the printer and router provides the strongest connection.

Before starting setup, ensure your printer is powered off and unpacked completely from its box. Remove any protective tape or plastic covers from ink cartridge areas. Insert the two ink cartridges firmly into their designated slots until they click into place. These cartridges must be present and seated correctly for the printer to function, even during the initial WiFi setup process.

Check that your computer or mobile device is already connected to the same WiFi network you plan to connect your printer to. This setup method is simpler and more reliable than attempting cross-network connections. Note your WiFi network's frequency band—this information may appear on your router or in your network settings.

Practical Takeaway: Test your WiFi signal strength at the printer's intended location by placing your smartphone there and checking the signal bars. If the signal is weak, relocate your router or printer before attempting setup to avoid connection failures mid-process.

Step-by-Step WiFi Setup Process Using the Printer's Control Panel

The HP DeskJet 3755 includes an on-board setup wizard that guides you through the WiFi connection process using only the printer's buttons and small display screen. This method requires no computer or additional device and represents the most straightforward approach for most users. Begin by pressing the power button to turn on the printer. Wait approximately 30 seconds for the device to complete its startup sequence and display its menu on the control panel screen.

Using the navigation buttons (typically arrow keys) on the printer's front panel, scroll through the menu until you see an option labeled "Setup," "WiFi," or "Network Settings." Press the button that confirms your selection, usually marked with a checkmark or "OK." The printer will display a message confirming that it is ready to search for available wireless networks.

The printer will scan for nearby WiFi networks and display them in a list on the control panel screen. Using the navigation arrows, find and highlight your network name (SSID) from this list. Network names appear exactly as you've named them, so if you've customized your network name beyond the default, look for that specific name. Press confirm to select your network.

When prompted, use the on-screen keyboard to enter your WiFi password. The printer will display letters and numbers on screen, and you navigate through them using the arrow buttons. This process takes longer than typing on a keyboard since each character requires multiple button presses. Enter your password carefully, checking each character as you go, because errors will prevent connection. Once you've entered the complete password, select the option to confirm or connect.

The printer will attempt to connect to your network. A message will appear indicating whether the connection was successful. If successful, you'll see confirmation text and possibly your printer's assigned IP address. The WiFi indicator light on the printer's body should now glow steadily, indicating an active wireless connection. If the connection fails, verify that your password was entered correctly and that your router is functioning properly before attempting again.

Practical Takeaway: Write down your printer's IP address once the connection succeeds. This address (appearing as four numbers separated by periods, like 192.168.1.100) lets you access the printer's settings from your computer's web browser later if you need to troubleshoot or adjust configurations.

Alternative Setup Methods Using Computer Software and Mobile Applications

If the control panel method proves difficult or unsuccessful, HP offers alternative setup pathways through computer software and smartphone applications. The HP Smart app, available for both Apple iOS and Android devices, provides a user-friendly method for connecting your printer to WiFi. This application guides you through setup with on-screen prompts and images showing exactly what to do at each step.

To use the HP Smart app method, download the application onto your smartphone or tablet from the Apple App Store or Google Play Store. Once installed, open the app and select the option to add a new printer. The app will search for nearby HP devices and should detect your DeskJet 3755 automatically. If your printer doesn't appear in the list, ensure that your printer's power is on and that your mobile device is within reasonable wireless range of the printer.

When the app finds your printer, it will prompt you to connect to the printer's temporary WiFi network. This preliminary connection allows your mobile device to communicate with the printer directly without needing to already be on your home network. Follow the app's instructions to connect to this temporary network. Once connected, the app will guide you through entering your home WiFi network name and password into the printer.

An alternative method involves downloading HP's setup software onto your computer from HP's official website. Visit the HP support page, enter your printer model number (DeskJet 3755), and the page will display driver and software options for your operating system. The downloaded setup file will install printer drivers and utilities that can detect and configure your printer's WiFi connection automatically or with minimal user input.

Both the app and computer software methods typically take 10 to 15 minutes from start to finish. These methods work particularly well if you experience any confusion with the printer's control panel
