Landscape mode doesn't work

[Aaron Williams]

I am using the a2ps supplied with SuSE Linux and am having problems with 
landscape mode not working.  Whenever it is supposed to print in landscape 
more, the output is not rotated.  It does not reach the bottom of the page 
and cuts off on the right hand side.

Portrait mode does seem to work, however.

I have a HP Laserjet 4 Plus (postscript version 2013.111).  Whenever I attempt 
to print in landscape the output appears as portrait.  I do not see this 
problem at work with the HP Laserjet 4SI and 5SI.

I have a duplex unit installed.
