I have a Dell 966 All in one printer and was happily using it in XP on my old laptop that died.  I got a new laptop with Windows 7 64 bit OS and it saw my printer, but had to download drivers to make work.  With new drivers for 966 used on Windows7 64 bit, printer prints fine, but get error message in background that says "Load Library Failed   C:\windows\system 32\spool\drivers\x64\3\dlcdsko.dll"  if I click OK then a second error message pops up which I also say OK and printer starts to print and will print entire document, apparently no matter how many pages.  The progress window that opens is odd with a black background, some writing on top of other writing but you can make out status and when printing done, that window closes.  Every document I print requires this activity.  Please advise proper fix for this error.  Thanks
