FS#595 - When trying to enumerate printers, don't block for a long time when one's busy
This is a particular problem when we have more than one model of the same printer family attached, and one or more of them are busy doing something -- but we can't query the serial number when the printer is claimed.
This may require a two pass approach -- first try to probe everything with minimal timeouts. If we don't succeed in finding the one we want, re-try the probe with longer timeouts. In both cases, we shouldn't report a failure until we finish walking the entire list.

Additional comments about closing: Current behavior is much improved. I'll re-open this if necessary, but for now, it works well enough.

number of claim attempts is now variable. Don't sleep if we're on our last attempt.
simple scan does not retrty claiming, but attaching still follows old logic.
