ok, a few quick questions.
just got a second hand XE-A203 cash register and am happy on the whole with it, but there are a few niggley things.
1. i cant get it to communicate with a pc, it installs the driver but the software just says it cant check if there is power
2. is there any way to get the decimal point to show after pressing subtotal when entering the cash given
3. is there any way to stop clerks from being able to do refunds so only the manager can do them

think thats it for now.
thanks in advance
