We have a problem with printing on occasion. Using Win7 Pro in a domain environment. When printing to a printer connected via ethernet that is a printer available on the domain we sometimes get a "local download document" trying to print before the actual doicument. It never does print and the neither will the document we are trying to print. It is not sepcific to one printer although the printers that we use are both Konica Minolta units. A reboot solves the issue and we can then print fine for a while.
