I have an HP Officejet 4500. When printing a single page it always shoots out a
extra, although blank, page. How can I stop this?

Another question, can Ubuntu keep track of the manilipulation of the pages when
printing on both sides? In Windoze this is taken care of automatically, telling
you when to remove, re-insert and print of the other side. Has anyone figured
out how to do this in Ubuntu?
