Good morning, I will appreciate the support.Because the thickness of the line in the print is different in the model.

Did you try disabling Plot object lineweights in the plot dialog box?

That could be a result of object lineweight as already suggested, or it could be in the lineweight entries in the pen assignments in the Plot style table [edit button in upper right corner in Plot dialog box].  Pen assignments would also be able to explain the color difference between the hard hat and the rest, which object lineweight would not, assuming it is drawn in a different but similar-looking color from the rest [color 1 vs. color 10, for example].

Solved, Thank you! Maximum!
