Need to know the model printer to provide assistance.

Thank you for your response WAWood, the Model is the HP Officejet 4500. There is no Model Number anywhere else on the unit.

The All in One had been working for many years until this year when the "HP Solution Center" software was replace by a strange symbol of an italic "f" and lower case "i" and displayed no links to continue...just the frozen display on the screen.
