I try to found a solution with the option Plot on NX. First things, with printer, all works fine but we haven't the linewidth (It's normal with this option).
I configure the printer for plotting and I have need to use the option (Best fit to page). This option allows when you plot to have the correct scale and orientation.
When I plot, I have 2 or 3 mm in the bottom outside the sheet. Do you know how solve this issue? I have test and test a lot of parameters but now I have nothing idea.
I don't understand why you need "best fit to page" to have the correct scale and orientation. I think you need "actual size" Sometimes it will need a bit of translation. The only solution I know is to just plot something, measure the result and correct for it.
Are you sure the paper size you choose is the same as the printer provides?
