printer_guy, wow! That's great information. As you can see from the previous post I had the wrong printer I was trying to download firmware for. The jetdirect cards seem to be okay but I'll take a closer look next time someone has the page spew problem.
Thanks a lot for the help. At this point it's probably not worth going after the firmware updates anyway. I hope in the near future we can upgrade to a newer printer in those spots anyway. Too bad as the 4100 just won't quit!
