If balance and printer are connected at the same Coulometer COM you need the
6.2125.010 and 6.2125.030 Adapters.
If the balance works only with 7 bit and the printer with 8 bit and if they are at the same
Coulometer COM, the balance has to be set to "space parity" and Coulometer/printer to 8
bit, "no parity".
