You’ve tried setting up HP Scan to Email with Gmail, but the scans never make it to your inbox. You’re not alone—this is a common issue, and the fix isn’t always obvious. Google blocks access by default, and your printer’s settings might be working against you. The real solution starts with understanding which security layer is actually stopping the connection.
Why HP Scan to Email Fails With Gmail
If you’re using Gmail with HP Scan to Email, you might run into issues because Google’s security settings don’t always play well with older printer configurations. Your HP LaserJet might fail to send email because it’s using outdated SMTP server settings—make sure it’s set to smtp.gmail.com, port 465 (SSL) or 587 (TLS). If two-factor authentication is on, you’ll need an app password for the printer. Network firewalls may also block outbound SMTP traffic, cutting off communication. Plus, if the shared email account password changes, you must update it on both Gmail and your HP LaserJet. Mismatched credentials mean no email goes through.
Fix Google Security Blocks for Printers
When Google flags your printer as a less secure app, it blocks access to Gmail, but you can fix this by enabling “Allow less secure apps” in your Google account settings. This lets your HP printer use Scan to email without interruption. Make sure you enter the full email address as the username in the printer’s settings. Use smtp.gmail.com with port 465 or 587 for secure connection. Double-check that the email address is correct and matches your Gmail account. While this works, remember Google may change policies, so keep an eye on updates. For better security, consider using a dedicated Gmail account just for Scan to email to protect your main full email from risks.
Use App Passwords for HP Scan to Email
Google’s move to block less secure apps means you now need a stronger way to keep your HP printer connected to Gmail for scan-to-email tasks. If you use two-factor authentication, you must generate an App Password. It’s a unique 16-character code Google provides for apps and devices that don’t support modern sign-in methods. Go to your Google Account’s Security settings, choose “App passwords,” then create one for your printer. Use this code instead of your regular password in the printer’s email setup. It grants access without exposing your main password. Keep it secure—anyone with it can use your account from that device. This simple step restores reliable scanning to your inbox.
Set Up Gmail SMTP on HP Printers Correctly
To get your HP printer sending scans via Gmail, start by entering smtp.gmail.com as the outgoing mail server, with port 465 for SSL or 587 for TLS. You’ll need to enable SSL in the settings to meet Gmail’s security standards. Make sure you turn on authentication and enter your full Gmail address—like username@gmail.com—plus your password. If you use two-factor authentication, generate an app password in your Google account and use that instead. This keeps your login secure while letting the printer connect. Double-check that all fields are filled correctly, as even small errors can stop emails from sending. A proper setup means your scans will reach your inbox smoothly.
Allow SMTP Traffic Through Firewalls
Through your firewall, you’ll need to explicitly allow SMTP traffic to guarantee your HP printer can send scans via email. You must open ports 465 (SSL) and 587 (TLS/STARTTLS) used by Gmail. Don’t forget to permit outbound SMTP traffic, or your printer won’t connect. Be sure to allow the printer’s specific IP address or its entire subnet. This guarantees consistent access even after reboots. You should also regularly check and update your firewall rules. Changes in network setup or Google’s server requirements might affect connectivity. Test SMTP access via your printer’s web interface to confirm the firewall isn’t blocking the connection.
Test Email From Your HP Printer
Start by accessing your HP printer’s web interface and navigate to the email settings to find the “Test Email” option. Use smtp.gmail.com with port 465 (SSL) or 587 (TLS) and confirm the full Google G Suite email is entered as the username. Send the test to verify setup. If it fails, check your network and firewall to allow outbound SMTP traffic. Sometimes, authentication issues block the test—even with correct settings. In those cases, try resetting your Google account password and update it on the printer. This often clears login errors. Keep your Wi-Fi stable and double-check each setting. A successful test means your printer can now send scans by email. Troubleshoot further only if problems persist.
Bypass Gmail Blocks With a Local SMTP Relay
You’ve tested the email setup directly through your HP printer, but if Gmail still blocks the connection, there’s a more reliable workaround. Set up a local SMTP relay server to bypass Gmail’s restrictions. It accepts scan emails from your printer and forwards them securely to your Gmail account. This intermediary gives you full control over authentication and security settings that often block direct access. It also handles changes in Google’s protocols smoothly, keeping your scans working. Plus, you can log and monitor every email attempt, making troubleshooting faster and easier. With a local SMTP relay, you avoid recurring authentication issues and maintain consistent, secure email scanning without relying solely on Gmail’s strict filters.
Reset Printer Email Settings and Update Firmware
If your HP printer’s scan-to-email feature stops working, resetting the email settings and updating the firmware can get it back on track.
- Reset the email setup through your printer’s web interface—clear old SMTP settings and re-enter Gmail’s correctly
- Update your printer’s firmware from HP’s official site to fix bugs and restore Gmail compatibility
- Confirm your email account has proper permissions—you’ll avoid silent authentication failures
- Update passwords on the printer if you’ve changed them recently—this tiny miss can break everything
- Run a test scan job right after—feel the relief when it finally delivers your scanned file
Scan to Email Alternatives for HP Printers
While Gmail’s restrictions can block your HP printer’s scan-to-email function, you’ve got better options that keep your workflow moving. Use a local SMTP server like Hamster to route scans directly to your inbox. Set up a dedicated email account with a provider that supports your printer’s SMTP settings. Try alternative email services with looser security than Gmail. Skip email entirely by scanning straight to cloud storage with apps like Dropbox or OneDrive. Or use mobile scanning apps over Wi-Fi to send files instantly. These fixes save time and cut frustration. You don’t need Gmail—just a smarter way to deliver scans where they need to go.
Frequently Asked Questions
Why Is My HP Scanner Not Scanning to Email?
Your HP scanner isn’t scanning to email because of incorrect SMTP settings, blocked ports, or Google security blocking access. You’ve likely got two-factor enabled without an app password, or your network’s firewall’s stopping the connection. Update settings and check your email auth.
Why Did My Scan to Email Stop Working?
Your scan to email stopped working because Google’s security blocked the printer’s access. You’ve likely got the wrong app password, outdated login details, or your firewall’s blocking the connection. Update settings and check your SMTP configuration to fix it fast.
Does Gmail Support Scan to Email?
Yes, Gmail supports scan to email. You can use your HP printer to send scans directly to your Gmail account. Just make sure you set up SMTP correctly and enable app access or use an App Password for authentication.
What Is the SMTP Server for Gmail for HP Printers?
You use smtp.gmail.com as the SMTP server for Gmail on your HP printer. It’s the right server to send scans by email, and you’ll need to enable SSL or TLS for a secure connection.
