Thank you for letting me know.
Since the printer works with PDFs and other apps, this is likely a Word or Office issue, not the HP printer driver.
Please try this:
- Open Word and create a new blank document.
- Go to "File" > "Print."
- Select "Microsoft Print to PDF."
- Check whether the Print Spooler stops.
If the spooler also stops, repair Office:
- Go to "Settings" > "Apps" > "Installed apps."
- Find Microsoft 365 or Office.
- Select the three dots > "Modify" > "Quick Repair."
- Restart the computer and test again.
If needed, run "Online Repair" afterward.
Please let me know if Word can print using Microsoft Print to PDF.
