Epilog Laser Driver

[Woodworker]

Hi,

I installed an ethernet connection for my Epilog Laser. It was working fine until I tried to print something else from a different printer, an HP Color Laserjet. I had the ethernet connection plugged in, and I plugged in the usb cable for my laserjet. It wouldn't print, and now I can't print from my Epilog Laser or any of my other printers! Has anyone had this problem or have any ideas of what I can do? Thanks.
