[Qgis-user] Printing to letter size landscape results in 8.5x8.5 image

[NoOp]

I am using the following (linux Ubuntu 9.10 Karmic):
$ apt-cache policy qgis
qgis:
  Installed: 1.4.0-2~karmic2
  Candidate: 1.4.0-2~karmic2
  Version table:
 *** 1.4.0-2~karmic2 0
        500 http://ppa.launchpad.net karmic/main Packages
        100 /var/lib/dpkg/status
     1.3.0-1~karmic9 0
        500 http://ppa.launchpad.net karmic/main Packages
$ apt-cache policy cups-pdf
cups-pdf:
  Installed: 2.5.0-8ubuntu1
  Candidate: 2.5.0-8ubuntu1
  Version table:
 *** 2.5.0-8ubuntu1 0
        500 http://archive.ubuntu.com karmic/universe Packages
        100 /var/lib/dpkg/status

and find that if I print to the cups-pdf printer from Print Composer
with the settng Ansi A (Letter; 8.5x11 inches) (Landscape) the result is
the image appears to be 8.5x8.5 inches.
  However, if I use the 'export as PDF' function, the image properly
scales to the full 8.5x11 inches.

It doesn't appear to be a cups-pdf issue as printing directly to my
Canon MP750 results in the same 8.5x8.5 inches.

Note: printing to the cups-pdf printer and Canon from all other
applications works without issue.

Is this a known issue? Any workarounds?
