printer network problems

[adamw30]

I have an HP Color LaserJet PRO MFP 3302dfwg printer.

I've been having trouble activating network scanning to my computer using the printer's control panel.

When I install the printer over the network, I have to manually enter the IP address/hostname to proceed. Then I get a message that the printer has been found, but it seems the firewall is blocking automatic detection (the firewall was disabled, and other things are working). After proceeding and completing the printer installation, I try to open HP Scan but get a message that communication with the scanner cannot be established. Make sure the device is turned on, that you're connected to the network, and that the network is functioning (the information is there, but it doesn't say anything specific).

The printer prints normally over the network, but it also scans ONLY when I use Windows applications (scanners and printers). The control panel doesn't work. The system detects the printer, the ports are unblocked, and it's connected to the same network, pinging, etc. The problem stems from the application itself. The application has access to private networks and isn't blocked, and everything is in place in the registry editor...

This shows how to scan to email from the printer console.

Some HP printers support Scan to Email on the printers control panel, but it must be configured first through the printer's Embedded Web Server (EWS). It is not enabled out of the box. This HP video shows how to configure the Laserjet Pro. Click the spoiler to get an explanation of what is done in the video.

Step 1. Find the printer's IP address
On the printer's touchscreen:
• Menu → Network (or Wi-Fi) → Network Summary
• Note the IPv4 address (for example, 192.168.1.120).

Step 2. Open the Embedded Web Server
On a computer connected to the same network:
1. Open a web browser.
2. Enter the printer's IP address in the address bar.
3. Log in as admin if prompted. The default PIN is printed on the label inside the printer (usually behind the front or toner access door).

Step 3. Configure Scan to Email
In the EWS:
1. Select Scan.
2. Select Scan to Email.
3. Create a new Outgoing Email Profile.
4. Enter:

Your email address
Display name
SMTP server
SMTP port
Authentication information

5. Save and use Save and Test to verify it works.
Typical SMTP settings
For G mail:

SMTP Server: smtp.g mail.com
Port: 465 (SSL) or 587 (TLS)
Username: your full G mail address
Password: Google App Password (not your normal password

if 2-Step Verification is enabled).
For Microsoft 365 / Outlook com:

SMTP Server: smtp.office365.com
Port: 587
STARTTLS enabled
Username: your full email address
Password: your account password or app password

Step 4. Scan from the printer
Once configured:
1. Place the document on the glass or in the ADF.
2. Tap Scan.
3. Tap Scan to Email.
4. Select your email profile.
5. Enter or choose the recipient.
6. Press Scan. The document is sent as an email attachment.
