We have several machines on our campus that are experiencing issues with the print spooler crashing constantly. As soon as we would start the spooler service, it would crash about 20 seconds later. I have removed all printers and drivers and then re-installed them. Our printers are installed via iPrint to our computers. We are using the Universal Print Driver 5.1 from HP. The computers are Dell laptops, Lenovo Laptops, and Dell Desktops. All of the models are current within 3 years. The OS is Windows 7 64 bit Enterprise. Any help would be greatly appreciated it. I have posted this on other forums and they are all coming back to the iPrint client. We are running the latest iPrint client 5.42 on these Windows 7 machines.
