After printing to a physical printer (PDF print driver did not have any effect) internet connectivity gets erratic and sometimes just fails. Reboot will correct it but printing again makes the problem return.

First thing I did was uninstall/reinstall the printer driver with no change in the behavior and then the user let me know she had two printers and printing to either one caused this behavior.

I plan on reinstalling the NIC driver but I was remoted in to the machine so that wasn't an option the first time around.

I've never seen this behavior before. Any suggestions on how to proceed? I will be physically at the machine soon so I thought I should check in for some input.

Thanks in advance for anything you have to offer.
