lineweights, again

I have the new v.7 of Bricscad and have set the pen/plot styles to match exactly as they existed in v.4. When I print (HP i9900) the lineweights are too, small. I can manipulate the lineweight in the Style Properties side of the Plot Style Table Editor to get close but would like a proper match. I have built both an standard and a metric .ctb but neither seems to be the answer. Where might I look for another solution?
