Hi @M-ike1987,
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 DeskJet Plus 4155 All-in-One Printer is encountering multiple issues, making it hard to pinpoint a single cause. Let’s take this step-by-step to diagnose and resolve the issues:
Step 1: Preliminary Checks
Restart Everything
- Turn off the printer, computer, and router.
- Wait for about 1-2 minutes and turn them back on in this order: router, printer, then computer.
Check Printer Status
- Ensure the printer is turned on, connected to the same WiFi network as your computer, and not in error or offline mode.
Inspect Ink Levels and Paper Tray
- Check if the ink cartridges have sufficient ink.
- Ensure the paper tray has paper loaded correctly.
Step 2: Common Errors and Fixes
Connection Issues
- If the printer shows as "offline" or "not connected," run the HP Print and Scan Doctor tool (Windows) or check your WiFi settings on the printer.
Print Queue Issues
- Clear any stuck print jobs:
- Windows: Go to Control Panel > Devices and Printers > Right-click on your printer > See what's printing > Cancel all documents.
- Mac: Go to System Preferences > Printers & Scanners > Select your printer > Open Print Queue > Clear the jobs.
Driver Problems
- Uninstall and reinstall the printer driver using the HP website:
- Download the HP Smart App or full feature software for your printer model.
- Re-add the printer through the app.
Firmware Update
- Update your printer’s firmware to resolve any known bugs. Use the HP Smart app or download firmware updates directly from the HP website.
Error Messages
- If the printer shows specific error codes, let me know. Many errors have quick fixes, such as resetting cartridges or checking for jams.
Step 3: Test Printing
Print a test page:
- On the printer, press and hold the Cancel and Start Copy Color buttons together until the printer starts printing a test page.
Try printing from different software or devices:
- Print a document from another device (e.g., phone, tablet) using the HP Smart app to see if the issue is device-specific.
Step 4: Advanced Troubleshooting
If the above steps don’t resolve the issue:
Reset the Printer to Factory Settings
- On the printer control panel, press and hold the Wireless and Cancel buttons for 5 seconds.
I hope this helps.
Take care and have a good day.
