%Example using embedded CCITT group 4 (G4) data.

%For optimal printing speeds, the scan data should be aligned with

%the printing orientation, which scans the long edge of the page.

%Fast scan direction for the image is bottom-to-top across the page.

%Slow scan direction for the image is left-to-right down the page.

%To get this data for a normal portrait oriented image, scan it as

%landscape with the original rotated 90 degrees clockwise. This can

%also be done as a post pass on the scan data.

%This scan direction requires no internal rotation for DocuPrint

%printers, although the PostScript code has a 90 degree rotation

%(counterclockwise) to compensate for the rotation performed in the

%scan step.
