We're considering using the Symbol OPOS driver, V3.31, to allow scanner support for our mix of 32- and 64-bit client PCs. Since this driver was introduced in 2010 (I believe), I'm concerned that we may use something that will be unsupported in the near future. As I stated in another post, we have a mess of mixed bitness client PC's and a homegrown application that can only be built on a 32-bit PC.
