Will upgrading to Windows 10 break my printer?

Episode 1260 (1:34:36)

Glenda from Aliso Viejo, CA
Microsoft Windows 10 upgrade

Glenda is concerned about upgrading to Windows 10 because when she upgraded from Vista to Windows 8, she lost the capability to print to her older printer and had to buy a new one. Leo says that upgrading to Windows 10 from Windows 8 won't break anything like it did from Vista to Windows 8. It's a more subtle jump.

How long will it take to upgrade? Leo says it depends on her bandwidth, but it shouldn't take longer than an hour.
