I am looking at purchasing a used mitsubishi eco 1630, the actual unit is in good shape, but the rip is ancient, Harlequin 5.1 running on a windows NT box. I am very leery about bringing in such an old operating system into our work flow. We would be printing from macs OS 10.5. Does anyone have this or a similar setup? any advice? We are using it for easy 1 and 2 color jobs. Thanks!
