Release 14 and Cadjet 2 problems

We are experiencing printing problems from release 14 to various plotters, but especially our in house encad cadjet 2. Plots are incomplete and at different line weights, etc. We are in Portland, Or., would be interested in recommendations of local consultants well versed in 14 and cadjet 2 plotters.

We have three computer stations, networked together, all with release 14 loaded. Autocad files are stored one one computer, so the other two open files, do work, save back to other computer. But..... we get different plot results from each computer. Even the computer that stores the files gives us results we don't like, for instance columns on plans come out light instead of dark.

We could use help on making sure each computer and program are set up to produce same results and that we are using a good 'standard', AIA or otherwise for line weight quality.
Thanks,
Robert
