Unable to connect printer to network

[Nadav123]

Unable to connect printer to new WiFi router. I followed the instructions on YouTube movie (https://youtu.be/GMCJ-vsGmHQ). At 02:50 the video shows some “Connect Printer to Wi-Fi” screen. I did not find how to reach this screen. 
I need to reach this screen in order to set SSID and password on printer.

@Nadav123, Welcome to the HP Support Community!

HP DeskJet Ink Advantage 3785 All-in-One Printer does not have a LCD screen. Let us try these steps to connect the printer on the network.

Restore network settings to default settings

Press the Wireless button and the Cancel button from the printer control panel at the same time, and then hold them for three seconds.

Connect the printer with WPS

1. Locate the WPS button on your router, but do not press it yet.

   If your router does not support WPS, skip to the next step to connect the printer with the HP Smart app.

2. Turn on the printer. If the printer is in sleep mode, press the Cancel button on the control panel.

3. On the printer control panel, press and hold the Wireless button  for at least 3 seconds or until the wireless light starts to flash.

4. On the router, press and hold the WPS button for 3 to 5 seconds or until it shows that the WPS connection process has started.

   NOTE: The printer stops searching for a WPS connection two minutes after the wireless button is pressed. If you were unable to press the WPS button within that timeframe, attempt these steps again.

   Once the printer connects to the wireless network, the blue Wireless light on the control panel turns on solid.

Note: Make sure the printer and the iOS device are connected to the same wireless network. 2.4GHz

To print from your iOS device:

1. Make sure the printer is turned on, ink cartridges are installed, and plain paper is loaded in the main tray.

2. Open the item you want to print, and then tap the Share icon  or  .

3. Tap Print or the Print icon  to open Printer Options.

4. Tap Select Printer to select your printer.

5. Change any of the following print job settings. Available settings vary depending on the app you are printing from, the print job type, and your printer.

   • Paper: Make any paper size changes on the printer. AirPrint automatically detects the paper size loaded in the printer or the size selected on the printer control panel. If the detected size is different than the paper in the tray, an error might display asking to confirm the size.

   • Number of copies: Select how many copies you want to print.

   • Black & White: Select to print in grayscale. This option only displays for color printers.

   • Double-sided printing: Print on both sides of the paper for certain file types.

   • Page range: Select specific pages within a document or webpage to print.

   

Let me know how this goes.
