Non-continuous linetype appearance are controlled by several variables, including:
LTSCALE The overall linetype scaling applied to all objects in the file.
PSLTSCALE When this is set to 1 (on), AutoCAD factors the viewport scale to the objects, so non continuous linetypes appear consistent in differently scaled viewports. PSLTSCALE = 0 (off) disables this feature.
MSLTSCALE When set to 1 (on), linetypes in the model space tab are scaled according to the annotation scale; when set to 0 (off) the annotation scale is not applied to the scale factor.
Lastly, remember many object types have their own property of linetype scale, too (CELTSCALE).
In you rparticular case, if linetypes look okay in model, but not in paper, my first suggestion is to set PSLTSCALE to 0, and see if that corrects it. Remember to regen to see the changes.
