Can't Print from AUTOCad

[cec]

My office recently got three new computers all with windows seven, we also upgraded to AutoCad Lt 2013. Now of the three computers only one can print to our kip 7100 from Autocad and the other two can not. The two that can't print from Autocad can print pdf's to the Kip just not .dwg files from CAD.

Need Help!

Thank You!

One has the correct drivers installed and the other two do not?
And are you sharing one single PC3 file or plotting to a system driver?
Can you print to the KIP from other applications on the failed PCs?

Are the other two PCs connected to the plotter?

So many things could be the problem, and you have chosen not to share what you've tried to fix and confirm is working in your post. Should we start guessing?
