There are no plans to support that printer in the older OSes. No offense meant but here's why.
In order to get the lower prices you could dump all old OS development and save a bundle on software costs.
Return it while you still can.
Some advice would be a great help. A brand new Dell 962 all-in-one printer scanner copier has just been bought for me, it was bought by someone who isnt in the slightest bit aware of system requirements of a product. This printer is only compatible with Windows XP, I am lumbered with Windows ME at the moment and am not really in the mood for change. Would anyone know if its possible to get some software that would enable me to get the printer to work with my OS? all other system requirements are ok. Any help would be greatly apreciated.
