Ron,
when we Z out our registers in the evening, it will tell us when the last z out was done, which is always the previous day. Sometimes though, the z out report will say the last z out was 2 days ago, which in fact it is wrong. The daily z outs are showing up on the server computer that we do every day, but why do the registers sometimes miss a day? We have tried everything. We leave the computers on for 10 minutes after each z out just in case it needed to transmit to the server, but even doing that, the register computers still intermittently keep missing a day with no rhyme or reason. Any ideas?
