In most cases and with most printers, printing via the printer pass-
through connector should not be any different than printing via the
computer’s own printer port. The printer pass-through connector
on the MiniSCSI 1350 can be used to connect a printer or any
peripheral device that normally connects to a parallel-printer
connector.
Note: The printer pass-through connector will only work
when the SCSI peripheral is attached and powered ON .
