Hi @noprintbob ,

Welcome to The HP Support Community.  

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

I understand you are facing an issue with your HP ENVY Pro 6400 series printer shows as "ready" in the HP Smart app but won’t print, try the following steps to resolve the issue:
 

Step 1: Check Printer Status

1. Ensure there are no error messages on the printer's control panel (e.g., out of paper, jammed paper, low ink).
2. Check the printer’s Wi-Fi or network connection:
   • Ensure the blue wireless light is solid (not blinking).
   • If the printer is connected via USB, ensure the cable is properly connected.

Step 2: Clear Print Queue

1. Press Win + R, type services.msc, and press Enter.
2. Scroll down to Print Spooler, right-click, and select Stop.
3. Open the following folder: C:\Windows\System32\spool\PRINTERS.
   • Delete all files in this folder.
4. Go back to the Print Spooler service, right-click, and select Start.

Step 3: Print a Test Page

1. Open Control Panel > Devices and Printers.
2. Right-click your printer, select Printer Properties, and click Print Test Page.
   • If this works, the issue is likely related to the app or document.

Step 4: Reinstall the Printer Driver

1. Open Settings > Devices > Printers & Scanners.
2. Select the printer, then click Remove Device.
3. Visit the HP Drivers & Software website.
4. Download and install the latest drivers for your printer.
5. Re-add the printer to your system.

Step 5: Check HP Smart App Settings HP printer setup (HP Smart app)

1. Open the HP Smart app.
2. Go to Printer Settings > Preferences or Network Setup.
3. Ensure the printer is set as the default and is not in offline mode.

Step 6: Test with a Different Document

1. Try printing a different file type (e.g., PDF, Word document).
2. Use another application to send the print job.

Step 7: Reset the Printer

1. Turn off the printer, unplug it from the power source, and wait for 1-2 minutes.
2. Plug it back in and turn it on.
3. Check the HP Smart app again to ensure the status updates.

I hope this helps.
