[REM] hw_drivers: Remove printers list from status

The status returned bby PrinterDriver contained a list of connected
printers to be used in Enterprise, to determine if the printer that was
selected in POS Config was used in the POS. We now read this status
from the db and we therefore don't need this anymore.

In Community the user only needs to know if there's a printer connected
to the Box. We just have to know if any printer is present.
