Hi. I'm David, and I'm happy to help you.
Remove the printers as follows:
- Press "Windows + I" to open Settings;
- Go to "Bluetooth & devices", then click "Printers & scanners";
- Click on a printer listed there, then click "Remove";
- Repeat this for every printer in the list, including default ones like "Microsoft Print to PDF".
If Windows automatically reinstalls any printer, let me know so I can give you an alternative.
If you have any questions, don't hesitate to ask.
