Hi @Cisco_Printer14,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The "Connection Error: 500" when printing from an iPad to your HP Color LaserJet Pro MFP M281cdw suggests a communication issue between the iOS device and the printer. Since printing from your HP laptop works fine, it seems to be an issue specific to AirPrint or email-based printing on your iPad.
 

Check Printer Connectivity

• Ensure your printer is connected to the same WiFi network as your iPad.
• Restart both the printer and the iPad.
• Check for any error messages on the printer’s display panel.

Restart the Print System on iPad

• Go to Settings > Bluetooth & Wi-Fi and toggle both off and on.
• Restart the iPad and try printing again.

Check AirPrint Support

• Open Safari or Notes and try printing a simple page (not an email attachment).
• If that prints, the issue may be specific to the email app.

Print Email Attachments Correctly

• Instead of printing directly from the email app, try:
  • Downloading the attachment first and then opening it in a different app like Files, Preview, or Adobe Reader.
  • Then select Share > Print and choose your HP printer.

Remove and Re-add the Printer

• On the iPad:
  1. Go to Settings > Wi-Fi > Select your Printer (if listed under Wi-Fi Direct) and Forget this Network.
  2. Open Safari > type “123.hp.com” and follow instructions to reinstall your printer.
  3. Restart both devices and try printing again.

Check HP Smart App (if using)

• If you use the HP Smart app, ensure it is updated.
• Try printing from within HP Smart rather than directly from Mail.

Reset Printer Network Settings

If none of the above steps work:

• On the printer control panel, go to:
  • Setup > Network Setup > Restore Network Defaults.
• Reconnect the printer to WiFi and try printing again.

I hope this helps.

Take care and have a good day.
