Hello my name is Sheldon and I am HP  customer executive. Many people ask “Why it is showing hp printer error offline?”. There are various reasons why an HP Envy printer is offline. It may be because the printer is not being correctly connected to the system or internet, an outdated driver, low ink or paper in the printer, or a paper jam. To fix an offline hp printer Confirm your connections and make sure your software is up to date, then check the error warnings on the printer's screen.
