I have a brand new dell, with factory installed Win7. Used migration tool to copy over old files and settings from old computer. Installed open office and firefox... nothing else. Installed 3 network printers, using the drivers provided automatically. 2 are newer Dell printers, one is an old Dot Matrix. These are all at an office I am supporting remotely, so I dont have the specifics with me right now. All of the printers disappear each day after reboot. Opening up the printers in control panel fails...box basically hangs...nothing ever appears. Reboots do nothing. Cannot re-add printers from network by "connecting". Cannot print to printers, or open printers. I got the printers to reappear after much tinkering, but did not do anything that obviously should have made any difference. I was contemplating reinstalling Win7, so I put the cd in and started the process, but stopped before getting past copying files. The printers worked for the remainder of that day, but disappeared the morning. Is there anything obvious I need to know here? This is the first Win7 system I have worked on. Thanks!
