If one wishes to do it themselves, Youtube or www.ifixit.com can help.

If not, then just call for a technician from the manufacturer of the printer.

You haven’t specified the problem, so I believe this link would have a lot: https://support.microsoft.com/en-us/windows/fix-printer-connection-and-printing-problems-in-windows-10-fb830bff-7702-6349-33cd-9443fe987f73
Besides if you do have any questions give me a call: https://clarity.fm/joy-brotonath

I am a problem solver, so if I am faced with a problem, I seek out the solutions until I find the answer that works.
