Lantronix xPrintServer Home Edition
As we do more and more on mobile devices, printing is often unavailable because only some printers can work directly with iOS's AirPrint capability. (In the Android world, printing is rarely an option.) Lantronix's small wireless print router solves that issue, AirPrint-enabling almost any network- or USB-attached printer. It's set and forget, though there's a management tool for small-office setups where you'd want to choose which printers to make public.
