printing via lpr

I've got an HP G55 printer running via CUPS. Everything normally prints
ok from StarOffice, but when I try to output a plain text file (lpr
file.txt) I get the first column cut off due to the unprintable area.
Like margin settings are off in lpr. Looked at the man of lp & lpr but I
didn't see anywhere to set them. I think it's in the 'options' (lpr -o)
but where do I find them?

Happy Holidays everyone!
