When I print dimensions, they print very light. Hard to read. I tried to change the font. I used Arial Black. This helped some but still pretty light.
Maybe the text color isn’t black. Try changing the color of the dimensions. Or maybe change the font to bold? Without seeing the SketchUp file it’s only a guess.
I am using the Arial Black font with the color black selected. This is better but still pretty light compared to the drawing.
How about sharing the SKP file so we have some hope of helping you? Are you printing directly from SketchUp or are you exporting an image and printing that?
Thanks for your help. I used a different printer. This solved the problem.
