Line weight problems between V8 and XM

Currently I am the only technician in my group who has the XM edition and I'm having problems printing drawings with the same line weights as the V8 users. We have the same plot tables loaded and same line weights used, but when I plot out the drawings through XM the line weights are never the same as the V8 drawings. We have looked at the pen strokes and they match, but don't know where else the problem might be coming from. Looking for any solutions. Thanks.
