    Do you have remote access to another computer on the same local
    network to confirm that printer's IP address is "192.168.1.20", as
    you expect, and it responds to ping command from another computer?
    
    Please answer other questions I asked:
    1. What is make\model of your printer?
    2. Is your printer connected to another PC using USB cable, or is it
    connected directly to the local network using a network cable (RJ-45
    patch cord), or is it connected using wireless connection?
    3. How was IP address "192.168.1.20" assigned initially to it? (Ex.
    Using physical screen and buttons on the printer itself, or it was
    configured automatically)

    I don't see any reason why your computer could not ping the printer,
    since you can ping gateway IP and access the Internet from it.
    I suspect printer's IP address has changed somehow, or it is in
    powered off state (some printers can power off themselves, if they
    were not used for a set period of time).
