lintype scale printing

Draftsight version R15 x 64  -  With various non solid line types, eg centre or phantom, regardless of the scale used the ps print always shows & prints a solid line.

I have seen advice to set psltscale to zero (instead of 1) & around 1 month ago that did work, now it makes no difference. It does make the screen image of a layout (ps) appear correct but then you print & it is back to solid. tried a couple of different printers & it made no difference.

I tried creating a test drawing at 1 to 1 scale in ms such that it would also be 1 to 1 in ps, so that there would not be a scale difference that might distort the line scaling, but still no good.

Very frustrating !

Fortunately I have access to a  Progecad licence as well, which does not have this problem so I was able to finish the job. I would like to stick with DS if possible but this issue has to be resolved.

Also related to printing -  I can create new print configs to suit my A4 & A3 requirement but the default setting is always the default, which makes sense except that I never use it. I would like to change the default settings but it is greyed out & seems to be inaccessible.
