When printing to save as pdf it gives me error!

Hi Kareem -
On macOS, please use the Rhino ExportAll command to create PDF files.
We can’t control what the default macOS Print procedure does.
-wim

what do you mean?
I want the simple Rhino print command to work properly !
can you fix it ??

No - as I said, we can’t control the macOS behavior for printing.
