Didn't solve the problem.
Having tried various things in the past, I am not willing to spend more time with it. Normally I have no need to print from SafeZone, but when on a trip with my laptop I might need to print.
I have Kaspersky IS on my main computer. KIS has a SafeMoney module which does permit printing. When this license runs out for Avast, I will probable put KIS on the laptop. It is less expensive to buy an AV that will license of 3 computers.
I guess Avast is a "work in progress." Maybe V8 will work out the bugs with the sandbox and SafeZone.
