Printer is not going through form my Dell laptop. I set up the bonjour and it shows up, but when I print, it shows, printing, then print error. Thoughts?

When you added it through bonjour, did it find its own printer or choose a generic one?  Also, be sure you restarted the machine as well.  Windows can be such a pain! If that doesn’t work then try to manually select the print driver in bonjour print wizard. I have also found that sometimes windows is happier with the previous version of the driver. In your case, the 8400 series rather that 8500 series if it’s available. Just a thought. Windows support is a bit outside my jurisdiction.
