Problems with printing

when i print my work, lines which are with dash spaces come out on paper like default lines !!!

where is a problem ?

Most likely it is with your linetype scale.

Are you printing from model space or paper space?

Are you printing to some sort of scale or to "fit"?

I draw, then when i print, i choose print window, crop out all work, then clik fit on paper !

linetype scale is 1 !

I guess you're saying that you print from model space and at no particular scale. Is that correct?

What is being drawn?

What size paper are you printing to?

I'm drawing kinda electro lines, and i need a boxes with dash spaces, on autocad there is these dash spaces, but when i print(on A4 format) there is single lines !

mby problem is that i used THICKNESS?

Why are you using Thickness?

Have you tried changing the linetype scale?

because, when i dont use thickness, and my linetype scale is 1, these dash spaces dont appear, even i have picked dash space linetype

Then you are working in 3D not 2D right? From your AutoCAD Help file:

Thickness

"Use the thickness property to give objects a 3D appearance."

i'm working on 2D

2D? Then you have no rational reason to be using thickness unless you are trying to give the appearance of 3D.

Have you tried changing the linetype scale? A simple yes or no will suffice.

yes now, my thickness ir 0, linetype scale 0.1 and there is dash spaces, but when i print they arent

Perhaps the length of the line you want to print and the size of the paper you want to print to causes AutoCAD to compress the line to such an extent that it "appears" it is continuous.
