Maria has a Windows 7 computer and with the end of life support for it, she's is looking to get a Chromebook but doesn't know which one is best. Leo says that she can still upgrade your Windows 7 machine to Windows 10 for free, and that would be cheap. But a Chromebook is a great option for someone who isn't tech-savvy. Her HP printer is rejecting her new cartridges. Leo says that's a known issue.

As for a printer, Leo recommends the Epson Ecotank printer.
