A couple of possible things to try.
- Turn printer off, then back on.
- Clear printer cache/jobs waiting in queue.
- If printer is connected via USB port, try another port.
- If you checked for driver
updates through Windows Update, try going to manufacturer's website.
- Try all print options (eg: right click document > print; file > print; etc.)
- If possible, try printer on a different computer.
- Check manufacturer's support site (usually support.lexmark.com, support.hp.com, etc.)
Probably more troubleshooting ideas but these are most common.
