Currently our customers are complaning about the anomaly, that the default printer is sometimes changed after printing *.pdf's with Adobe Reader. I have never heard of a problem like this before and am even not able, to confirm this behaviour.
That is why I want to ask you, if you have ever heared of something similar like this. Under which circumstances does Adobe Reader print on another non-default printer automatically? Btw. I don't know how to handle this problem so far.
