how serious is the problem, after diagnostic scanner reveals, losing compression in 1 of the 6 cylinders in my motor?

Very serious, Also requires further diagnosis of why piston has no compression to determine extent of seriousness. 
However, what kind of scanner reads piston compression?

Year, Make, Model, mileage? I don't understand how a scanner can measure compression. That is something that needs to be physically checked by a gauge with sparkplug removed. The scanner might be showing a missfire. As in, fuel injector not working or a sparkplug not sparking.

What engine and sensor are you using to measure the digital "relative" combustion chamber compression PSI numbers? It most likely can't be any better of a compression balance test most talented mechanics can determine by listening to engine run for 3 seconds.

How serious is it? I'd rely upon scope results to tell you that there may be a problem. Beyond that, you need to have a compression test done (and perhaps a few other tests and observations to verify what's actually going on. There are a number of things that can happen that can lower the compression in one cylinder. A good tech will do the appropriate testing and then make a conclusion. Is it serious? Could be, but don't panic 'till all the results are in.

Thank you everyone, your answers are extremely helpful. All 4 actually. I can tell by your response, compression is not something determined by the scanner. in all likelyhood, the mechanic was referencing a missfire. and misspoke .Probably  to lay the groundwork for a bigger job rather than smaller.I'm not saying he's unscrupulous, but I know they're out there! Anyhoot, thank-you again!
