Ok, don't know how or why this happened but it did. I run win. 7 and use a deskjet 930c. Tonite I attempted to print an adobe file for the womens' ncaa basketball tourney. It would not print under my deskjet 930c setting, but somehow a hp 970 driver worked...don't get it how it happened but i got my printout. When it asked me which printer to choose from I chose the 970 which appeared out of nowhere.... something connected with adobe maybe??
