HP Officejet all in one printer (Magnolia 98199)

This printer was great until I stopped using it for a few months and when I tried to use it again the paper came through without a printing. I am not handy so I have no idea what to do but maybe someone else will. There are no power cords which is not helpful.. I would estimate the size to be 20 in wide and approximately 10 in deep, plus five or six inches tall. You can print or scan on it and it is very lightweight
