Printer Paper and the Drawing Sheet

One potentially confusing concept is that of the printer paper versus the drawing sheet. Printer paper means the physical sheets of paper that go through the printer. The drawing sheet is the total surface area on which your drawing will be printed. The drawing sheet can correspond to a single sheet of printer paper, or it can span multiple sheets of printer paper.
Both the printer paper and the drawing sheet have adjustable sizes and orientations. This provides a great deal of flexibility when you want to print a large drawing on multiple sheets. You could, for example, print a poster in landscape orientation three feet wide and two feet tall. You could print this virtual sheet out on 32 sheets of 8.5" x 11" paper oriented in portrait, or on 30 sheets of the same size paper oriented in landscape.
