I recently purchased a refurbished Inspiron 17 5767 with Windows 10 for wifey. Startup went smoothly until I tried to install my Lexmark S305 wireless printer. It is important to note that I've been using my Dell Inspiron 3847 desktop which has been running Window 10 for several months and printing without any problems. When I tried to add the printer to the laptop, it corrupted things (APC Index Mismatch?). I've tried everything I can think of...including reinstalling after a clean reset several times...all to no avail. Dell tells me it is Lexmark's fault and they have no solution except providing me with a reinstallation file and telling me to ask Lexmark for new drivers. Makes no sense to me that my Dell desktop can print but the laptop can't. Any ideas?
