Actual Paper Size

This term is used to identify the coordinate system used by actual plotters on a paper.

Plotter coordinates of lower-left corner of the actual paper are either zero (0,0) or are negative to the coordinates of upper-right corner (the plotter origin (0,0) is in centre of paper). The coordinates of the upper-right corner of actual paper are always positive. The X-dimension of the actual paper is always greater or equal to its Y-dimension (in non-rotated state).

Notice:

The coordinate system with origin in centre of paper is usually used only by large format HP-GL plotters. The HP-GL/2 language places the coordinate origin always to lower-left corner of paper.
