I installed a new printer and started printing a new document, a script error message popped up on my computer. I cannot fix it. Why is this happening. It will print an old document frm my files. I also noticed that an ethenet cable is connected to a wireless router and a modem. Is there a cable that supposed to connect from printer to computer? Please help me. I have an HP Ethernew all in one printer, Officejet 6500 E709 series.
