I have recently purchased new Lenovo H15 PC with Windows 7 64 bits. I still have my old A940 printer from Dell and I would like to make it working with my new PC. Dell internet site says that this two are compatible and advices Vista driver. It is not clear for me which vesion 32 bits or 64. I would like some help with compatibility issue. 64 bits version versus 32 bits and if my printer will work with 32 bits driver or how can I find correct driver for my old printer. I would approciate any help very much.
