1-36 Guide to Using Page Description Languages
When an image is used in a document, it is placed in a specific
orientation on a page. The orientation of fast and slow scan
directions for the image relative to those for the entire output
page is important. If the directions for the image do not match
the directions for the page, extra processing must be done at the
printer to reorder the image data.
The most time-consuming processing is rotation, shown in the
figures below using US Letter paper size.
