dell_rah,
Run Delete Print Jobs to remove stuck print job(s) from the queue, then restart your computer.
Then try this tweak...
Start, control panel, device manager.
Go to the USB Controller section and click the + sign.
Go to each USB Root Hub and right click on it, left click properties, left click power management. Uncheck the box, allow computer to turn off this device to save power.
Restart your computer.
Try the printer for a few days and let me know if you have any problems.
