After updating to Mac OS X 10.6.5, you may find that attempting to print in landscape mode in Adobe applications will result in the print coming out in portrait mode, thus cropping the image.

This bug is only affecting PostScript printers, and is limited to applications that generate PostScript output natively (i.e. Adobe Creative Suite and some versions of Freehand). The confirmed workarounds are:

  • In InDesign or Illustrator, change Paper Size from “Defined by Driver” to the correct paper size.
  • In Photoshop, rotate the canvas 90 degrees, then print in portrait mode
  • In Acrobat, rotate the page 90 degrees, then print in portrait mode

Apple is aware if this bug, which seems to be caused by the ptstops filter included with 10.6.5’s version of CUPS. Some people have reported success with replacing /usr/libexec/cups/filter/pstops with the version from 10.6.4, and then setting the permissions on the pstops file to match the way they were, but I’d say this is a use-at-your-own-risk-workaround.
