Sequence A (origin top left, row scan order):

0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 0 0 0 1 1 1 1 0 0 0 1 1 1 1 1

1 0 0 0 0 1 1 0 0 0 0 0 0 0 0 0 0 0

Sequence B (origin bottom right, column scan order):

0 0 0 0 0 0 0 0 1 0 0 0 0 0 1 1 0 0 0 1 1 1 1 0 0 1 1 1 1 0

0 0 1 1 0 0 0 0 1 0 0 0 0 0 0 0 0 0

Regardless of which scan order is chosen, the scan proceeds in one direction (called the fast scan direction) through each parallel slice in turn, progressing through the slices in a direction called the slow scan direction.

In sequence A, the fast scan direction is left to right and the slow scan direction is top to bottom. For sequence B, the fast scan direction is bottom to top, and the slow scan direction is right to left. The terms left, right, bottom, and top only have meaning based on the orientation of the image on the page.

When DocuPrint NPS executes a PostScript program, the principal product for each page is an image just like the images that can be incorporated into PostScript programs. The image data is transferred to the imaging hardware as a sequence of values in laser scan order.
