Hi @Dave2600,

Welcome to the HP Support Community!

Thanks for reaching out!

I understand your HP DeskJet Plus 4100 series (HP6402CF) is showing an error printing message and isn’t able to print even a simple PDF or the test page. Let’s try a few steps to get this fixed:

1. Restart devices

Turn off the printer, unplug the power cable for 60 seconds, then plug it back in.

Restart your computer.

2. Check the printer connection

If using Wi-Fi, ensure the blue wireless light is solid (not blinking).

If USB, reconnect the cable and try a different port.

3. Update or reinstall the driver

Go to HP Support Drivers page.

Download and install the full feature software/driver for your printer model.

4. Try HP Smart App

Install the HP Smart app (Windows, Mac, iOS, or Android).

Run the diagnostics and test print from the app.

5. Test with another file/app

Sometimes the issue is file-specific. Try printing a simple text document (e.g., from Notepad/Word).

If that works, the problem may be with the PDF viewer (try Adobe Acrobat or a different app).

I hope this helps.
