Landscape printing

[Ray Stacey]

We are running cups 1.4.7 on Solaris 10. I'm trying to print a postscript file from our application using the command
lp -o landscape -o PageSize=Legal -d treekill2 INV-R200.r01.17206.ps.

The file prints on legal paper, however the first page is landscape and each subsequent page is rotated 90 degrees. So the first page is fine, the 5th page is fine, the 9th page is fine ....

Any ideas??
