Hello and welcome to Techspot.
I`m not sure I understand what it is you`re saying.
As far as I`m aware, your Lexmark printer should be connected to your computer via a usb cable.
First switch on the power to the printer, but don`t plug it into a usb port on your computer yet.
Insert the installation cd that came with your printer, and install the drivers first.
During the driver installation, you may be prompted to connect your printer. If not just let the driver installation complete.
Now you should be able to connect your printer to your computer.
