OPOS service objects export a uniform interface; however there may be

slight differences between the same types of devices from different vendors

and models. Queries of OPOS properties reveal these differences. Below

listed properties, methods, and events are DATALOGIC device specific

return values. Other DATALOGIC service objects with different interfaces

may produce slightly different results. Developers are advised to consider

all error conditions in designing an application.
