Install or reinstall a printer without making things worse
If the printer is already partly working, do not remove everything first. Check the existing setup, then add or re-add only when it is actually needed.
If you use Windows
See whether the printer is already there
Open Settings → Bluetooth & devices → Printers & scanners. If the correct printer is listed, test it before removing it.
If it is missing, use Add device
Turn the printer on. For Wi-Fi, make sure the printer and PC are on the same normal network. For USB, connect the cable directly while testing. Then use Add device.
Try one page
If it prints, stop. You do not need extra printer software just because a download page says you do.
Remove and add again only after simpler checks fail
Remove only the printer you are troubleshooting, add it again, then test before installing anything else.
If you use a Mac
Open Printers & Scanners
Go to Apple menu → System Settings → Printers & Scanners. If the printer is already listed, test it first.
Add the printer normally
Click Add Printer, Scanner, or Fax. If a compatible printer offers AirPrint, macOS can normally use it without a separate driver download.
If a re-add is needed, remove only this printer
Do not jump straight to Reset Printing System. That is a much broader reset and should stay near the end of troubleshooting.
When extra manufacturer software makes sense
Some printers need their manufacturer's software for special scanning, finishing, account-code, or setup features. If you need it, start from the official printer support directory rather than searching for a driver download.
A printer install should not turn into an unexpected remote-access session or a request for gift cards, cryptocurrency, or bank information. See Scam Safety if anything about the support offer feels strange.
