Firefox always prints landscape

Printing from OpenOffice.org is fine, but whenever I try to print from 
Firefix, the output comes out in Landscape with the top part of the text 
chopped off. The Print Preview looks fine.

Google hasn't helped much; "about:config" and filtering for "print" 
doesn't show anything obviously out of place (but I don't really 
understand most of the options here); some of the Googling indicates 
that Xprint is somehow involved (I don't really understand Xprint, it's 
purpose or it's manner of working), but when I run

 export $XPSERVERLIST=`/etc/init.d/xprint get_xpserverlist`

like some Google pages indicate, I get this error:

 bash: export: `=:64': not a valid identifier

When I run "xplsprinters" I get:

 xplsprinters:  no printers found for printer spec "".

I've uninstalled all my printers from the cups web interface 
(http://localhost:631) and added back in just the one (remote, 
networked) HP LJ 4200 printer with which I'm concerned. All the settings 
that I can find indicate it should be printing portrait, on Letter 
paper. A test print from the cups web interface prints properly.

Any help would be appreciated.

Thanks!
