A:AnswerYes, it absolutely can. You can connect the printer to the Wi-Fi in your home, the same Wi-Fi your computer is connected to and print wirelessly that way. Or you can buy the proper cord to hardwire the printer to your computer tower and print that way. Either way works.
A:AnswerYes, it will still print, but the colors may be muddy because the remaining ink will have to fill in where the missing ink would otherwise appear on your paper.
A:AnswerI have Printer AI app for iphone in which you just scan any document with single tap and print that document in proper format. This app is very easy to use & connect with printer with wi fi or bluetooth. If you want that app then search on app store "Printer AI" or https://shorturl.at/ale8V

A:AnswerDo a Google search for "WF-3820 downloads". You should get a link to a page on the Epson website where you can download the correct software and drivers.
