I have noticed that printers and scanners are still giving more resolution in one direction per inch than the other direction. Does anyone know why this is?

is that increasing resolution in the line of the paper feed means that the print nozzles have to be smaller and closer together, or one has to print in two passes, slowing down print speed. The same principle applies to scanners.

Because the mechanisms for moving horizontally and vertically are entirely different, and so subject to different constraints.

Or to put it perhaps more correctly - one is carried out by a mechanism (moving a head) - the other is specified by a premanufactured part (print head/ scanner CCD). The constraints are still different - mechanical ones being of lower tolerance.
