Check the settings for that line type.
The lengths of the dashes and gaps may be too big or the gaps may be too small.
Also if it is set to "Scale Independent (Paper Size)", the size of the dashes and gaps will always remain the same printed size, so as you change drawing scale the length of the dashes and gaps will appear to change, but they will always print the same regardless of the scale.
If it is set to "Scale with Plan (Model Size)" the dashes and gaps will always appear the same regardless of the scale - so they will actually print bigger or smaller depending on the scale.
