Hello,
I am installing a new Lenovo ThinkCentre desktop in to a POS system, W7 64bit, and plan use an existing kithen printer having a parallel interface. The desktop has 2 slots open for PCIe base spec 2.0 x1 slots. I can easily find adapter cards which meet PCIe base spec 1.0 but not 2.0. Will they work?
