I just upgraded my OS to Windows 7 x64 and I am using Autocad 2009 x64 SP3, We have several HP devices in our office and when I try creating a plot to one of these devices, Autocad will crash. I have tried the lates universal drivers from HP, their XP x64 drivers as well their standard 32 bit XP drivers. All have the same result. I can print through other programs to these devices, just not Autocad. Is anybody else running itto this issue? If so, do you have a fix?
