A queue was matched by NAME alone, so a bay whose printer had moved, or whose
queue was built on a driver the site has since replaced, looked converged and
printed to the wrong device. Absence was fixed; drift was not.
Set-ShopdbPrinters.ps1 now repoints a queue whose port does not match the
address ShopDB holds, and swaps a queue built on the wrong driver. Both are
things ShopDB is authoritative about: where the printer IS, and what drives it.
CORRECTED IN PLACE with Set-Printer, never removed and recreated. The queue keeps
its name, its sharing, its permissions, and whoever has it as their default keeps
it - which is what makes this safe to run every cycle on a live floor. There is
still no removal code path in this script at all.
Two guards, because a repair that breaks a working printer is worse than drift:
the driver is only swapped when the wanted one is actually staged, and
-WhatIfOnly reports both kinds of correction without making either.
Verified on Windows against a queue that had the right name, the wrong port, the
wrong driver AND was the logged-on user's default: both fields were corrected and
the queue was still the default afterwards. The earlier no-op guarantees were
re-run and still hold - nothing assigned changes nothing, and an assignment with
no default leaves the user's own default alone.
