The new Mimaki printers are using USB.
Mimaki JV33 Specifications
So you need:
(1) USB printer cable sufficiently long to reach your printer
(1) 4-port network router. Lynksis, Netgear, D-Link, whatever.
(2) Ethernet patch cables long enough to reach your router.
Set up the router according to the included directions. Hook up the PC's to the router with the patch cables. Run "network setup wizard" and enable file and printer sharing. Connect the printer via USB to the RIP station and install drivers that came with it. Share the printer in the printer control panel. Share any drives you want shared under Win Explorer.
That should do it.
