Serious printing issue after 10.6.5 update

Same problem here . . . very frustrating.

I've been trying different things to figure this out. Text Edit and Word seem to be fine when printing landscape. Adobe Reader is fine printing a landscape PDF if Portrait is selected in the Page Setup. Can't seem to get an InDesign document that is created in landscape to print in landscape regardless of the different combinations (on different printers). So is it an Adobe specific issue?

I've now printed in landscape with quite a number of programs with no problems. It seems to be an Adobe issue.

I finally got InDesign to print properly (2 sided printing in landscape mode). In Setup, I had "Defined By Driver" in the Paper Size. Once I selected the actual paper size, it works.

This exact problem happened before with one of the 10.5 or maybe 10.4 versions. It was Apple who fixed it, not Abobe, and the fix posted above also worked back then..

I can confirm that this problem is unique and occurring with Mac OS X 10.6.5 and the HP Drivers 2.5.2 for HP LaserJet and DesignJet printers. Most likely, the problem is with the Mac OS X 10.6.5 update rather than the HP Drivers 2.5.2 because:

(1) The HP Drivers 2.5.2 update has been out for a week, and was working just fine with Mac OS X 10.6.4.

(2) Some are reporting problems with printers from a different brand (like Epson).

(3) Mac OS X 10.6.5 includes CUPS 1.4.5 (10.6.4 included 1.4.4). This is most likely a CUPS bug.

You can report this bug in two places:

(1) At the Apple Bug Reporter: http://developer.apple.com/bugreporter

(2) At the CUPS site directly: http://www.cups.org/roadmap.php, then click "Submit Bug or Feature Request." CUPS (Common UNIX Printing System) is the open-source printing engine that Apple uses for Mac OS X. Many Linux and other UNIX systems also use it. In 2007, Apple assumed control of the CUPS project, although it remains open-source and free-software (GPL).

Quick fix: rotate canvas 90° and print portrait.

Yes , i also facing this problem, very headache, what can i do is quite troublesome for us to printing large file if we need to rotate to potrait, it is not the right way to solve the problem. pls let us know how to do , any update ?

Yes, I also have the same landscape printing problem after 10.6.5 update with Acrobat, Illustrator, InDesign & Photoshop (CS5)
Printer: Xerox Docucolor 242 and 240 (Fiery Rip)

I can also confirm the workarounds mentioned above work for me:
Indesign & Illustrator - Change 'Paper Size' 'Defined by driver' to the correct paper size
Photoshop - Rotate canvas - Not great but works.
Acrobat - Rotate page

I have also reported the bug to Apple.

Confirmed here too!

I'm having the same problems and I'm about to lose it this morning. What do I need to do to stay informed?

cant printing landscape in ps or illustrator after update.
other software havent the problem.

10.6.5
