You can print drawings as PDF files, save them as plot files ( .plt ) for printing with printer/plotter, or print them on a selected printer. You can also change the line thickness of different colors. Tekla Structures provides a real-time preview of drawings in the Print Drawings dialog box.
You can also use the so called "old" printing functionality where you use the Printer Catalog dialog box and Tekla Structures printer instances. To do this, see Print drawings using Printer Catalog printer instances (old printing).
