I was pinging a printer to see if it was online, and noticed something weird. The ping time increments, and then drops back down again cyclically. Other printers of the same model aren't doing that and there are no print jobs going to it. I was pinging it because a print monitor application was suck at "Initial check of printer status..."
PS C:> ping 192.168.2.65 -t
