printing extra blank page after each form print using Linux

[Tony Freehauf]

i just installed a new Xerox 3500N laser printer. Xerox says it is fully 
pcl5 compatable.
it appears to work great.
the issue is after each form is printed an extra blank page is printed
We are running Linux  2.4.20-18.7smp & filepro 5.0
the print command i am using is lp -dprintername -o nobanner -s
what should i do?
thanks
old tony
