The suggestion doesn't quite match the reality of cups-filters 1.0.83. A corrected patch is: A PDF file containing pages with page width greater than page height (a landscape page) has such pages automatically rotated anticlockwise by 90 degrees unless the PPD file has a *LandscapeOrientation line saying 'Minus90', which results in a 90 degree rotation clockwise. To turn off the feature on a job-for-job basis use lp -d <print_queue_name> -o nopdfAutorotate <document> On a per queue basis use -o nopdfAutorotate as an option to lpadmin. Note that the 'landscape' and 'orientation-requested=4' options of CUPS take precedence and are applied before 'pdfAutorotate' or 'nopdfAutorotate'.
