Compatibility among PSF-Supported Printers

The following sections describe compatibility considerations when routing jobs among PSF-supported
printers.

Page Presentation

Page presentation refers to the position of a printed page of data on a sheet. PSF supports two page
presentations:
vPortrait, or narrow forms, in which the printed page is viewed with the shorter edges of the form at the
top and the bottom of the page and the longer edges at the sides of the page
vLandscape, or wide forms, in which the printed page is viewed with the longer edges of the form at the
top and the bottom of the page and the shorter edges at the sides of the page
All currently marketed PSF-supported printers have the same default media origins. Because the media
origin relates to the print direction (ACROSS, DOWN, BACK, and UP), it also is used in determining the
page presentation. For continuous-forms printers, the ability to use forms that feed through the printer with
either a narrow or a wide leading edge adds another factor to the determination of page presentation.
See Figure 54on page 158 for examples of media origins and print directions supported by PSF printers.
