Hello Henny,
It's great to find a place to talk about POS systems.
I really don't know if some people here develop this kind of software or it's dedicated to users trying to find help with their systems and/or hardware.
In my case, as mentioned before, I'm developing a POS software for a client and found myself with a problem with a certain hardware. I'm new to POS so that could be it too

The client purchased the Datalogic Magellan 8300 Scale/Scanner, it seems to be a great product but for me it has been a pain in the... It's supposed to be easy to use and program but that has not been my case. I have downloaded the OPOS drivers from the dataogic website, it includes a test software that I've been able to use for the scanning functonality and later use in my POS. But ths scale part doesn't work you either get timeouts or "scale not ready" messages IN THEIR TEST SOFTWARE nad in my tests I get the same. I'm using .NET and POS For Net for my software.
Does anybody have a clue? Any help would be much appreciated.
